Custom Webhook Types Pro

You can create your own webhook types and add them to Freeform. To create your own hook, you must first make the desired webhook class and either implement the Solspace\Freeform\Library\Webhooks\WebhookInterface interface or extend the Solspace\Freeform\Library\Webhooks\AbstractWebhook class, which already implements that interface.

To begin, let's make an example webhook class named CustomWebhook:

Slack

The Slack webhook allows you to define a message that will be sent to the Slack channel of your choosing. To set it up, you must first create a Slack App, and then use the generated webhook URL in the Freeform Slack Webhook edit page. Then enter the desired message, which is a Twig template, where you can call on and variables.

Zapier

The Zapier webhook lets you pass your submitted form data to Zapier where you can link it to any other webhook that Zapier provides an integration for.

The payload posted to Zapier looks like this:

{
  "form__id": 1,
  "form__name": "Freeform form",
  "form__handle": "freeformForm",
  "form__color": "#8ba2a8",
  "form__description": "This is a Freeform Form",
  "form__returnUrl": "",
  "id": 1001,
  "dateCreated__date": "2018-12-31 14:00:00.000000",
  "dateCreated__timezone_type": 3,
  "dateCreated__timezone": "America\/Los_Angeles",
  "uid": "18ca11b9-bd4f-4530-9e51-f7a67ac84ec2",
  "token": "v3bJsQf5o1cYaLhzJTnn8NAiWI9gn1J4JmTpPS4Es1OZetyQS5wDO2DrAdNieiEc9KFnaBh6CcTRD9xjBf48NQfr8XxxUr1HDvj6",
  "firstName": "John",
  "lastName": "Doe",
  "message": "A custom message"
}

Generic

Generic webhooks simply send a json POST request with the submitted payload to the specified webhook URL. The payload looks like this:

{
  "form": {
    "id": 1,
    "name": "Freeform form",
    "handle": "freeformForm",
    "color": "#8ba2a8",
    "description": "This is a Freeform Form",
    "returnUrl": ""
  },
  "id": 1001,
  "dateCreated": {
    "date": "2018-12-31 14:00:00.000000",
    "timezone_type": 3,
    "timezone": "America\/Los_Angeles"
  },
  "uid": "18ca11b9-bd4f-4530-9e51-f7a67ac84ec2",
  "token": "v3bJsQf5o1cYaLhzJTnn8NAiWI9gn1J4JmTpPS4Es1OZetyQS5wDO2DrAdNieiEc9KFnaBh6CcTRD9xjBf48NQfr8XxxUr1HDvj6",
  "firstName": "John",
  "lastName": "Doe",
  "message": "A custom message"
}

Adding your own webhook types

You can create your own webhook types and add them to Freeform.

To create your own hook, first, you must make the desired webhook class and either implement the Solspace\Freeform\Library\Webhooks\WebhookInterface interface or extend the Solspace\Freeform\Library\Webhooks\AbstractWebhook class, which already implements that interface.

Let's make an example webhook class named CustomWebhook

<?php

namespace Custom\Plugin;

use GuzzleHttp\Client;
use Solspace\Freeform\Events\Forms\AfterSubmitEvent;
use Solspace\Freeform\Freeform;
use Solspace\Freeform\Library\Webhooks\AbstractWebhook;

class CustomWebhook extends AbstractWebhook
{
    /**
     * @return string
     */
    public function getProviderName(): string
    {
        return 'My Custom Webhook';
    }

    /**
     * @param AfterSubmitEvent $event
     *
     * @return bool
     */
    public function triggerWebhook(AfterSubmitEvent $event): bool
    {
        $form       = $event->getForm();
        $submission = $event->getSubmission();

        $json = [
          'form' => $form->getName(),
          'submission' => $submission->title
        ];

        $client = new Client();
        try {
            $client->post($this->getWebhook(), ['json' => $json]);

            return true;
        } catch (\Exception $e) {
            Freeform::getInstance()->logger->getLogger($this->getProviderName())->error($e->getMessage());
        }

        return false;
    }
}

Then, we register it by listening to the WebhooksService::EVENT_FETCH_TYPES event in our custom plugin init method:

<?php

namespace Custom\Plugin;

use Solspace\Freeform\Services\Pro\WebhooksService;
use Solspace\Freeform\Events\Integrations\FetchWebhookTypesEvent;

class TestPlugin extends Plugin
{
    public function init()
    {
        parent::init();

        // Listen for the Fetch Webhook Types event
        Event::on(
            WebhooksService::class,
            WebhooksService::EVENT_FETCH_TYPES,
            function (FetchWebhookTypesEvent $event) {
              // Add the previously created Custom\Plugin\CustomWebhook class
              // by passing its fully qualified name to the event
              $event->addType(CustomWebhook::class);
            }
        );
    }
}

After these steps, your Webhook type will be available in the Create new webhook page.
