This page is about the menu SETTINGS->PAYMENTS->PAYMENT GATEWAYS->CUSTOM GATEWAY

Required skills: html, programming

1 Introduction

You can create an interface to an external (not integrated) payment gateway.

The booker will be shown a button which will take them to the specified URL with the value from "Post Data" included as an HTML POST.

2 Transfer to Custom Gateway

The post data is sent to the custom gateway as if it came from a normal HTML form being submitted

Both the URL and POST fields can contain template variables to include values from the booking.

A special template variable [PAYMENTAMOUNT] will contain the value of the deposit when booking and the value of the payment request when used for payment requests.

i.e. deposit=[PAYMENTAMOUNT]&bookid={BOOKID] will post fields deposit and bookid to the external gateway.

The custom gateway POST data is posted from the users browser when they click the pay button.
This means the POSTED data will be visible in the page source code and should not contain any secret or private data.

3 Webhook to notify of payment status

A notify URL is available for the external gateway to report a successful collection of the deposit.

The notify will add the deposit to the booking invoice and trigger updates to booking status and email notifications to guest and host.

The notify must post a key field with a value that matches to setting and contain at least 6 characters.

The data should be sent as HTML POST form data

Notify URL https://api.beds24.com/custompaymentgateway/notify.php

The notify should contain the following POST fields:
key = value in custom gateway key setting
bookid = the bookid of the booking

These POST fields are optional:
status = booking status, 0 (cancelled), 1 (confirmed), 2 (new), 3 (request)
amount = amount of the deposit collected
description = description of payment for invoice item
payment_status = status of payment for invoice item
txnid = unique id for this payment to prevent false duplicates

A success will have HTTP 200 response with no text. If there is any text content in the response, it will be an error message which means it was not successful.

4 Payment gateways with specific requirements

The payment values can be first posted to your server. Your server can process the data and convert it into the format required by the payment gateway. Finally redirecting the guest to the payment gateway with the data in the required format.
