Without Plugin so I want to learn through codes ..

Answer 1

API endpoint

First you need to build your own API endpoint to receive Typeform Webhook payload. I assume you will be building this in PHP since you are using Wordpress.

You can create a webhook.php file in your Wordpress installation, eg. in /wp-content directory:

<?php
$headers = getallheaders();
$header_signature = $headers["Typeform-Signature"];
$secret = "abc123";  // replace with a unique webhook secret

$payload = @file_get_contents("php://input");
$hashed_payload = hash_hmac("sha256", $payload, $secret, true);
$base64encoded = "sha256=".base64_encode($hashed_payload);

if ($header_signature !== $base64encoded) {
  die("invalid signature");
}

// now you can process webhook payload
// see https://developer.typeform.com/webhooks/example-payload/
$data = json_decode($payload);
$definition = $data->form_response->definition;  // form definition
$answers = $data->form_response->answers;        // respondent answers

// you could save it to your wordpress database
// code below depends on what questions you have in your typeform
require_once "../wp-load.php";
global $wpdb; // see https://developer.wordpress.org/reference/classes/wpdb/
$wpdb->insert('my_typeform_data', array(
    'name'         => $answers[0]->text,
    'phone_number' => $answers[1]->phone_number
));

Setup webhook

Now you can setup webhook for your typeform:

• click Connect in top menu
• click Webhooks
• click Click Add a webhook button
• enter URL to your webhook script, eg. https://example.com/wp-content/webhook.php
• click Save webhook button

To secure your webhook:

• click Edit button next to your webhook
• enter custom secret (see the $secret variable above)

For testing:

• click the View deliveries button next to your webhook
• click Send test request button
