This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Forms: 3rd-Party Integration


Send Contact Form 7, Gravity Forms, or Ninja Forms Submissions to a 3rd-party Service, like a CRM. Multiple configurable services, custom field mapping. Provides hooks and filters for pre/post processing of results. Allows you to send separate emails, or attach additional results to existing emails. Comes with a couple examples of hooks for common CRMs (listrak, mailchimp, salesforce). Check out the FAQ section for add-on plugins that extend this functionality, like sending XML/SOAP posts, setting headers, and dynamic fields.

The plugin essentially makes a remote request (POST) to a service URL, passing along remapped form submission values.

Based on idea by Alex Hager “How to Integrate Salesforce in Contact Form 7“.

Original plugin, Contact Form 7: 3rdparty Integration developed with the assistance of AtlanticBT. Current plugin sponsored by Stephen P. Kane Consulting. Please submit bugs / support requests to GitHub issue tracker in addition to the WordPress Support Forums because the Forums do not send emails.


Please note that this documentation is in flux, and may not be accurate for latest rewrite 1.4.0

  1. add_action('Forms3rdPartyIntegration_service_a#', $response, $param_ref);
    • hook for each service, indicated by the #this is given in the ‘Hooks’ section of each service
    • provide a function which takes $response, &$results as arguments
    • allows you to perform further processing on the service response, and directly alter the processing results, provided as array('success'=>false, 'errors'=>false, 'attach'=>'', 'message' => '');
      • success = true or false – change whether the service request is treated as “correct” or not
      • errors = an array of error messages to return to the form
      • attach = text to attach to the end of the email body
      • message = the message notification shown (from CF7 ajax response) below the form
    • note that the basic “success condition” may be augmented here by post processing
  2. add_action('Forms3rdPartyIntegration_service', $response, $param_ref, $sid);
    • same as previous hook, but not tied to a specific service
  3. add_filter('Forms3rdPartyIntegration_service_filter_post_#, ...
    • hook for each service, indicated by the #this is given in the ‘Hooks’ section of each service
    • allows you to programmatically alter the request parameters sent to the service
    • should return updated $post array
  4. add_filter('Forms3rdPartyIntegration_service_filter_post', 'YOUR_HOOK', 10, 4);
    • in addition to service-specific with suffix _a#; accepts params $post, $service, $form, $sid
  5. add_filter('Forms3rdPartyIntegration_service_filter_args', 'YOUR_HOOK', 10, 3);
    • alter the args array sent to wp_remote_post
    • allows you to add headers or override the existing settings (timeout, body)
    • if you return an array containing the key response_bypass, it will skip the normal POST and instead use that value as the 3rdparty response; note that it must match the format of a regular wp_remote_post response.
    • Note: if using response_bypass you should consider including the original arguments in the callback result for debugging purposes.
  6. add_action('Forms3rdPartyIntegration_remote_failure', 'mycf7_fail', 10, 5);

    • hook to modify the Form (CF7 or GF) object if service failure of any kind occurs — use like:

      function mycf7_fail(&$cf7, $debug, $service, $post, $response) {
      $cf7->skip_mail = true; // stop email from being sent
      // hijack message to notify user
      ///TODO: how to modify the “mail_sent” variable so the message isn’t green? on_sent_ok hack?
      $cf7->messages[‘mail_sent_ok’] = ‘Could not complete mail request:** ‘ . $response[‘safe_message’];

    • needs some way to alter the mail_sent return variable in CF7 to better indicate an error – no way currently to access it directly.

  7. add_action('Forms3rdPartyIntegration_service_settings', 'YOUR_HOOK', 10, 3)
    • accepts params $eid, $P, $entity corresponding to the index of each service entity and this plugin’s namespace, and the $entity settings array
    • allows you to add a section to each service admin settings
    • name form fields with plugin namespace to automatically save: $P[$eid][YOUR_CUSTOM_FIELD] $rarr; Forms3rdPartyIntegration[0][YOUR_CUSTOM_FIELD]
  8. add_action('Forms3rdPartyIntegration_service_metabox', 'YOUR_HOOK', 10, 2)
    • accepts params $P, $entity corresponding to the index of each service entity and this plugin’s namespace, and the $options settings array (representing the full plugin settings)
    • allows you to append a metabox (or anything else) to the plugin admin settings page
    • name form fields with plugin namespace to automatically save: $P[YOUR_CUSTOM_FIELD] $rarr; Forms3rdPartyIntegration[YOUR_CUSTOM_FIELD]
  9. add_filter('Forms3rdPartyIntegration_debug_message', 'YOUR_HOOK', 10, 5);
    • bypass/alternate debug logging
  10. add_filter('Forms3rdPartyIntegration_plugin_hooks', 'YOUR_HOOK', 10, 1);
    • Accepts an array of contact form plugin hooks to attach F3p to, and returns that array. Modify result to attach to additional plugin hooks, like GF edit.
  11. add_filter('Forms3rdPartyIntegration_service_filter_url', 'YOUR_HOOK', 10, 2);
    • hook a function that takes the $service_url, $post_args and returns the endpoint $url
    • used to modify the submission url based on mappings or other information
    • $post_args contains the body and other wp_remote_post details

Basic examples provided for service hooks directly on plugin Admin page (collapsed box “Examples of callback hooks”). Code samples for common CRMS included in the /3rd-parties plugin folder.

From the website and Handpicked Tomatoes:

Transparent and Holistic Approach

Transparency is good. It’s amazing how many web design sites hide who they are. There are lots of reasons, none of which are good for the customer. We don’t do that. I’m Stephen Kane, principal web craftsman at HandpickedTomatoes, and I’m an Orange County based freelancer who occasionally works with other local freelancers and agencies to deliver quality web solutions at very affordable prices.
We work to earn the right to be a trusted partner. One that you can turn to for professional help in strategizing, developing, executing, and maintaining your Internet presence.
We take a holistic view. Even if a project is small, our work should integrate into the big picture. We craft web architecture and designs that become winning websites that are easy to use and to share. We custom build social network footprints on sites like linkedin, facebook, twitter, youtube, flickr, yelp!, and google places and integrate them into your website to leverage social marketing. We help you set up and execute email campaigns, with search engine marketing, with photography, with site copy and content and anything else that you need in order to have a successful Internet presence.
Through this holistic approach, we work with clients to grow their sales, improve their brand recognition, and manage their online reputation.


  • Admin page – create multiple services, set up debugging/notice emails, example code
  • Sample service – mailchimp integration, with static and mapped values
  • Sample service – salesforce integration, with static and mapped values


  1. Unzip, upload plugin folder to your plugins directory (/wp-content/plugins/)
  2. Make sure at least one of Contact Form 7, Gravity Forms, or Ninja Forms is installed
  3. Activate plugin
  4. Go to new admin subpage “3rdparty Services” under the CF7 “Contact” menu or Gravity Forms “Forms” menu and configure services + field mapping.
  5. Turn on ‘debug mode’ to get emailed a copy of the submission+response data, until you’re satisfied everything works, then turn it off


I need help / My form isn’t working

Turn on ‘debug mode’ from the admin page to send you an email with:

  • the current plugin configuration, including field mappings
  • the user submission (as provided by CF7/GF/Ninja)
  • the post as sent to the service (applied mapping)
  • the response sent back from the service, which hopefully includes error codes or explanations (often is the raw HTML of a success/failure page)

Submit an issue to the [GitHub issue tracker][] in addition to / instead of the WP Support Forums.

How do I add / configure a service?

See [Screenshots][] for visual examples.


  1. Name your service.
  2. Enter the submission URL — if your “service” provides an HTML form, you would use the form action here.
  3. Choose which forms will submit to this service (“Attach to Forms”).
  4. Set the default “success condition”, or leave blank to ignore (or if using post processing, see [Hooks][] – this just looks for the provided text in the service response, and if present assumes “success”
  5. Set an optional “failure message” to show if the remote request fails. Can include the “nice explanation” as well as the original message provided by the contact form plugin.
  6. Allow hooks for further processing – unchecking it just saves minimal processing power, as it won’t try to execute filters.
  7. Map your form submission values (from the CF7/GF field tags) to expected fields for your service.
    • 1:1 mapping given as the name (from the HTML input) of the CF7/GF field and the name of the 3rdparty field
    • For GF and Ninja Forms, you may map either by the field name or the field label
    • You can also provide static values by checking the “Is Value?” checkbox and providing the value in the “Form Submission Field” column.
    • The “Label” column is optional, and just provided for administrative notes, i.e. so you can remind yourself what each mapping pertains to.
  8. Add, remove, and rearrange mapping – basically just for visual clarity.
  9. Use the provided hooks (as given in the bottom of the service block).
  10. Add new services as needed, drag/drop mappings and service boxes.
How can I pre/post process the request/results?

See section Hooks. See plugin folder /3rd-parties for example code for some common CRMs, which you can either directly include or copy to your code.

I need to submit multiple values as…
  • By default, if more than one value appears in the post request for the same field/key, they will be joined by the ‘separator’ value like &post-values=a,b,c.
  • However, if you use [] as the separator it will instead create multiple keys like &post-values[]=a&post-values[]=b&....
  • Use [#] to retain the numerical index: &post-values[0]=a&post-values[1]=b&...
  • Use [%] to place the numerical index at desired location; specifically useful with nested fields via Xpost below (and issues #11 and #7).

If you instead need to combine/nest fields, check out Forms: 3rdparty Xpost.

How do I make a GET request instead of POST?

Since v1.7.6, it’s an admin setting for GET and POST, but for anything other than those two that you’d write a hook.


See ‘Hooks’ section, #5 of and the source code.

You’ll need to perform wp_remote_get inside that filter and set $post_args['response_bypass'] with the response, something like:

function my_3rdparty_get_override($post_args, $service, $form) {
    $post_args['response_bypass'] = wp_remote_get($service['url'], $post_args);
    return $post_args;
How do I dynamically change the URL?

Use the hook Forms3rdPartyIntegration_service_filter_url. (see “Hooks” section)

What about Hidden Fields?

Using hidden fields can provide an easier way to include arbitrary values on a per-form basis, rather than a single “Is Value?” in the Service mapping, as you can then put your form-specific value in the hidden field, and map the hidden field name generically.

For convenience, you can install the Contact Form 7 Modules: Hidden Fields. This plugin originally included the relevant code, but it was causing issues on install, so is no longer bundled with it.

How do I export/import settings?

Use the “Forms 3rdparty Migration” plugin, which lets you export and import the raw settings as JSON.
You can also export settings from the original plugin [Contact Form 7: 3rdparty Integration][] and “upgrade” them for this plugin (although > 1.6.1 you will need to reselect forms).

How do I set headers?

You can also set headers with “Forms 3rdparty Xpost” plugin:

How do I show a custom message on the confirmation screen?

The failure message is shown by default if the 3rdparty post did not succeed. You can add custom messaging to the plugin’s (GF, CF7, Ninja) email or success screen response with something like:

class MyPlugin {
    public function MyPlugin() {
        add_filter('Forms3rdPartyIntegration_service', array(&$this, 'adjust_response'), 10, 2);

    public function adjust_response($body, $refs) {
        // use 'attach' to inject to regular email
        // use 'message' to inject to page
        $refs['attach'] = 'custom message in email';
        $refs['message'] = 'custom message on page';
new MyPlugin(); // attach hook
How do I conditionally submit? (if field == …)

Use hook ‘…use_submission’ to check the form submission (pre-mapping), making sure to pick the appropriate scenario, like:

add_filter('Forms3rdPartyIntegration_use_submission', 'f3i_conditional_submit', 10, 3);
function f3i_conditional_submit($use_this_form, $submission, $sid) {
    // if there was a specific value -- skip
    if(isset($submission['maybe-send']) && 'no' == $submission['maybe-send']) return false;
    // if there was a specific value -- use
    if(isset($submission['maybe-send']) && 'yes' == $submission['maybe-send']) return $use_this_form; // or true, i guess
    // if there was a value for it (e.g. for checkboxes) -- skip
    if(isset($submission['if-not-send'])) return false;
    // if there was a value for it (e.g. for checkboxes) -- use
    if(isset($submission['if-send']) && !empty($submission['if-send'])) return $use_this_form; // or true, i guess

    return $use_this_form; // or `false`, depending on your desired default

If you want to check after the fields have been mapped, you can “reuse” the hook ‘…service_filter_args’ and return false to skip, rather than bypass:

add_filter('Forms3rdPartyIntegration_service_filter_args', 'f3i_conditional_post', 10, 3);
function f3i_conditional_post($post_args, $service, $form) {
    // your skip scenarios, checking `body` subarray instead
    if(isset($post_args['body']['maybe-send']) && ...) return false;

    // regular behavior
    return $post_args;
How do I resend a service call?

Using public instance functions send and handle_results:

$f3p = Forms3rdPartyIntegration::$instance;
$debug = $f3p->get_settings();
// $sid - maybe get it from the current filter
// $form - maybe get it from the current filter
// $submission - probably save it somewhere, or rebuilt it from a database entry, etc
// $service = $f3p->get_services()[$sid];

$sendResult = $f3p->send($submission, $form, $service, $sid, $debug);
if($sendResult === Forms3rdPartyIntegration::RET_SEND_STOP || $sendResult === Forms3rdPartyIntegration::RET_SEND_SKIP) return;

$response = $sendResult['response'];
$post_args = $sendResult['post_args'];

return $f3p->handle_results($submission, $response, $post_args, $form, $service, $sid, $debug);
How do I include part of the response in another service call?

Excellent free plugin to send your emails contacts to SugarCRM or SuiteCRM like I do. Works perfectly for years. Keep this supported, please.
19 Luulyo, 2021
Fantastic plugin, very useful and most important thing: still works in Wordpress. Now I’m using Wordpress 5.7.2 and this plugin still works very well! I’ve just one suggestion: keep updated this plugin, please!!! 😉
14 Maarso, 2020
Works as good as any paid plugin–without requiring you to add your account credentials. Providing a plugin developer with admin accounts logins for a company’s CRM platform is a disaster waiting to happen. Not saying those premium plugin companies would do anything malicious but hard to warrant the risk when using POST or GET and OIDs with hooks to transfer the data and tying to a campaign keeps the account safe. Word of advice… if you’re getting redirect errors make sure you don’t use hyphens or underscores in the source field ID and select “Enable data forwarding to the success location” in the Pardot form handler.

It is a great plugin! I use it to join Ninja Forms with Mailrelay and it works perfectly.

I have tested with Salesforce and it works fine. Thanks.

  • copy service button
  • Ninja Forms are back! Can use Ninja Forms plugin v3.0+ again.


  • debug message truncation with configure hooks
  • use hook ...debug_truncation to set field length limits for each section


  • adding per-service delimiter, supports newlines
  • ‘add new service’ button after metaboxes
  • minor ui fixes


  • destination mapping is textarea to make other plugins easier (e.g. newlines in xpost formatting), hooks ..._service_mappings_headers and ..._service_mappings_values to add more columns


  • exposing http method (get/post); result redirection


  • late-bind GF confirmation for script tags


  • another slight fix to make GF Resend do submission hooks too (so Reformat will work with it as well)


  • slight refactor of before_send to make reposting GF submissions easier

  • fix minor conflict between Inject Results and Post-Again


  • added injection hooks for Forms: 3rdparty Inject Results — use via $form = apply_filters(Forms3rdPartyIntegration::$instance->N('inject'), $form, $values_to_inject);


  • refactored internal methods to make them reusable externally, specifically for ‘forms-3rdparty-postagain’ plugin

  • added URL filter to allow customizing GET requests with post body arguments, or shortcodes
  • filter added to fplugin_base to allow multiple attachments per github #62
  • fix github #68
  • ‘secret’ debugging feature for error dump if logging after unable to send email: add a truthy value to post mapping with 3rdparty key _json

  • fix array value without index placeholder bug introduced in github #43
  • final bugfix to #55 (default options mode array)
  • tried to address Xpost issue #7, but not the right place for it

  • debug logging hook
  • fixed #52 – some hosting providers rejected arbitrary sender addresses
  • more options for debug mail failure logging


  • Can now map GF and Ninja Forms by field label as well as id per issue #35 (map by name)

  • quick fix for global section toggle bug


  • conditional submission hooks (see FAQ)
  • removed somewhat useless ‘can-hook’ setting, since I assume everybody wants success processing. Comment via github or author website contact form if you really need it.

  • Fix for longstanding (?) Firefox admin bug (issue #36) preventing field editing/input selection


  • fix form plugin checking when multiple contact form plugins used at same time


  • integration with Ninja Forms
  • refactored CF7 and GF integrations to take advantage of new FPLUGIN base (to make future integrations easier)
  • defined upgrade path

Due to the new common form extension base, the way forms are identified in the settings has been changed.
Deactivating and reactivating the plugin (which happens automatically on upgrade, but not FTP or other direct file changes) should correct your existing settings.

Depending on how many services you have configured, the upgrade path may DESELECT your form selections in each service or otherwise break some configurations.
If you are concerned this may affect you, please export the settings so you can reapply your selections.


  • Updated cf7 plugin to match their latest changes.
    • using new way to access properties
    • removed remaining support for all older versions of CF7 (it was just getting complicated)

Trying to add some clarity to the admin pages


  • multiple values treated differently depending on separator: ‘char’, [], or [#]
  • static values treated the same as dynamic (so they get above processing)
  • fix: php5 constructor re:


  • totally removing hidden field plugin — seems like even though it wasn’t referenced, it may have caused the “invalid header” error during install
  • admin ui – js fixes (configurable section icons via data-icon; entire metabox title now toggles accordion)
  • stripslashes on submission to fix apostrophes in ‘failure response’ textarea


  • hook ...service_filter_args to allow altering post headers, etc
  • fix: removed more args-by-reference (for PHP 5.4 issues, see support forum requests)
  • tested with WP 3.8, CF7 3.6


  • fix: failure response attaches to ‘onscreen message’ for Gravity Forms
  • fix: (actually part of the next feature) failure response shows onscreen for Contact Form 7
  • customize the failure response shown onscreen — new admin setting per service (see description)


  • protecting against unattached forms
  • Github link
  • global post filter Forms3rdPartyIntegration_service_filter_post in addition to service-specific with suffix _0; accepts params $post, $service, $form, $sid
  • admin options hook Forms3rdPartyIntegration_service_settings, ..._metabox
  • fix: gravityforms empty ‘notification’ field
  • fix: admin ui — ‘hooks’ toggle on metabox clone, row clone fieldname
  • fix: service hooks not fired multiple times when both GF and CF7 plugins are active
  • fix: Gravityforms correctly updates $form array


  • Fixed “plugin missing valid header” caused by some PHP versions rejecting passing variable by reference (?) as reported on Forum support topics “Error on install” and “The plugin does not have a valid header”, among others
  • Rewrote admin javascript to address style bug as reported on forum post “fields on mapping maintenance screen misaligned” and via direct contact. Really needed to be cleaned up anyway, I’ve learned more jQuery since then 😉
    • Dealt with weird issue where clicking a label also triggers its checkbox click
  • Other general ui fixes
  • More “verbose” endpoint-test script (headers, metadata as well as get/post)


  • Bugfixes
  • cleaned up admin JS using delegate binding
  • added “empty” checking for 3rdparty entries to avoid dreaded “I’ve deleted my mappings and can’t do anything” error
  • timeout option
  • fixed CF7 form selection bug
  • conditionally load CF7 or GF only if active/present; note that this plugin must init normally to check CF7


  • Bugfixes
  • Added “Label” column for administrative notes



  • Added failure hook – if your service fails for some reason, you now have the opportunity to alter the CF7 object and prevent it from mailing.


  • Added check for old version of CF7, so it plays nice with changes in newer version (using custom post type to store forms instead, lost original function for retrieval)
  • see original error report


moved “external” includes (hidden-field plugin) to later hook to avoid conflicts when plugin already called


changed filter callback to operate on entire post set, changed name


fixed weird looping problem; removed some debugging code; added default service to test file


moved filter to include dynamic and static values; icons


added configuration options, multiple services


base version, just directly submits values
