Configuration

The configuration for the webhooks can be found at Settings > API.
There must be an accessible URL / IP address where the data should be sent to.
You can choose which content type you want to use. "Normal (PHP-Post) means application/x-www-form-urlencoded and is best used for PHP-applications. "JSON" means application/json and is best used for all different applications.

How to use

For an integration into a web shop you will create a Payrexx Gateway. After the transaction has been performed, you will get a notification request to your server. You can identify the transaction by paymentLinkId or referenceId in Invoice object.

Data

The data will be either sent in JSON format or as HTTP POST form-data.

Depending on the information you want to track in your system, please go to the object specification:

Examples

Currently, we only have an example written in PHP.

Download full PHP example with a corresponding MySQL database: click here to download

<?php

/**
 * The data of the POST request
 * @var array $transaction
 */
$transaction = !empty($_POST['transaction']) ? $_POST['transaction'] : array();

if (!empty($transaction)) {
		$invoice = $transaction['invoice'];
 	  $customFields = $invoice['custom_fields'];
 	  $contact = $transaction['contact'];
}

Retries

When activated for a webhook, the platform will try to resend the webhook based on the following policy:

immediately (max. 1 - 1.5 minutes after first synchronous attempt)
15 minutes after last attempt
1 hour after last attempt
2 hours after last attempt
4 hours after last attempt
24 hours after last attempt
24 hours after last attempt
24 hours after last attempt
24 hours after last attempt
24 hours after last attempt

Please note that those attempts will be asynchronously triggered.

Timeout

The server needs to send a response within 20 seconds. Otherwise, the request times out. The log shows HTTP status 0 and response body "Operation timed out after 20000 milliseconds with 0 bytes received".
