Paytabs provides you with a collection of API endpoints which used to process all payments, regardless of whether they are through either your own payment pages, the managed payment pages, or if you are using the hosted payment pages. 
Repeat billing is a feature that allows merchants to send repeated payable invoices to their customers at predefined intervals (weekly, monthly, or annually) for subscription products, or services, and it is currently supported via our Merchant dashboard.    

You can learn more about how you can initiate and manageg your Repeat Billing payment through PayTabs merchant dashboard by clicking here.


Note that in order to create any Repeat Billing agreements, you MUST have a secured terms & conditions URL configured inside your PayTabs profile, so if you do not have it already configured, you should contact your account manager or customer care and provide them with the URL to configure it for you.

The Available Optional Parameters

Besides the above-mentioned required parameters, PayTabs provides you with several optional parameters, each of which empowers you with a different feature and the ability to customize your payment request as much as possible it could be. The specification of these optional parameters is clarified below:


Parameter 

Data Type 

Min 

Max 

Required 

Purpose 

return 

STRING

-

255
(Valid URL)

❌

The return URL is the URL that PayTabs will redirect the customer to after he finishes the payment process (whether it's authenticated or not). It will redirect the customer with a POST response that is sent with the client/cardholder redirection through his browser containing the basic transaction information once the payment process ends (whether the customer cancels, paid, or failed to pay). It depends on the customer's actions, which means if the customer closes the browser right after the payment without waiting to be redirected back to your system, you will not receive this response.
  
 What is the Return URL vs the Callback URL? 

To know more about this parameter please click here.

callback 

String

(Valid URL)

 

❌

The callback response is a server-to-server POST response that is sent (to a pre-defined HTTPS URL) with the full detailed transaction information once the payment process has ended (whether the customer cancels, paid, or failed to pay). It does not depend on the customer's actions; the response will be sent anyway.

The Payment Page Experience 


As mentioned in "3.1.1 Hosted Payment Page | Payment Workflow", by creating the payment page, you will receive the redirect URL "redirect_url" within the response, which you will use to redirect your client to this payment page. Once you have redirected your client, the client browser will display the following page to the client.




The Merchant Dashboard Page Experience 


ONCE and ONLY if the customer completes the above payment, a new agreement will be created in your merchant dashboard and you will be able to manage and view all the agreement history, related transactions, and invoices. If you are looking to learn how you can manage your agreement, you should visit our Repeat Billing article.
