Typeform Webhook PHP

A secured PHP wrapper for Typeform service.

Install

First step is to create a new webhook endpoint on your typeform account/workspace.

Second, you'll need to generate a random string. for example, via terminal:

$ ruby -rsecurerandom -e 'puts SecureRandom.hex(20)'

Then, Update the webhook setting secret on your workspace "connect" section.

Next step is to install the wrapper using Composer:

$ composer require usyme/typeform-webhook dev-master

Receive typeform response

Native

require __DIR__ . '/../vendor/autoload.php';

use Usyme\Typeform\Webhook\Exception\AuthenticationFailedException;
use Usyme\Typeform\Webhook\Exception\BadPayloadFormatException;
use Usyme\Typeform\Webhook\Webhook;

$webhook = new Webhook('{personal_key}');

try {
    $response = $webhook->getResponse('{secret_key_from_header}', '{response_payload}');
} catch (AuthenticationFailedException $exception) {
    // Invalid received secret key
} catch (BadPayloadFormatException $exception) {
   // Bad received response payload format
}

Symfony

This library is built for project based on Symfony, that's why we prepared some class helpers to simplify the integration of typeform with symfony/http-foundation & symfony/form components.

class TypeformController
{
    /**
     * @param Request        $request
     * @param WebhookRequest $webhookRequest
     *
     * @return Response
     */
    public function webhook(Request $request, WebhookRequest $webhookRequest): Response
    {
        try {
            // Fetch the typeform response directly with $request object.
            $response = $webhookRequest->getResponse($request);
        } catch (AuthenticationFailedException $exception) {
            // Invalid received secret key
        } catch (BadPayloadFormatException $exception) {
            // Bad received response payload format
        }
        
        // ...
        
        // Or if you want to use the symfony's form component directly
        // you need to handle your request object, we're simulating a simple
        // post request using the handleHttpRequest() method.
        try {
            // In this case we're replacing our $request->request parameters
            // by the typeform data. So our $request object is now up-to-date :)
            $webhookRequest->handleHttpRequest($request);
        } catch (AuthenticationFailedException $exception) {
            // Invalid received secret key
        } catch (BadPayloadFormatException $exception) {
            // Bad received response payload format
        }
        
        // ...
    }
}
