For Developers


Splitit allows merchants to offer personalized installment payments for their customers anytime and anywhere, using their existing credit card, with no changes to the merchant’s risk.

The Splitit service works as an intermediate layer between the merchant’s platform and their existing payment gateway. New installment transactions are sent to Splitit (instead of being sent to the gateway) and we relay the transaction to the existing gateway.

Our documentation is designed to help programmers integrate with Splitit API as fast and easy as possible, using one of our integration methods.

Splitit Checkout Workflow
In order to better understand how to integrate Splitit into the workflow, it is important to understand the transaction flow while using Splitit:

  1. The shopper inserts his personal details on your checkout page and selects Splitit as the payment method.
  2. The shopper inserts his credit card details and chooses the payment period for the installment plan.
  3. The shopper reviews the payment schedule and approves the Splitit T&C’s.
  4. Transaction complete!

Splitit can be implemented in different ways, depending on how deep you would like to go into the coding. if you are PCI compliant or not, if the UI/UX is the #1 priority in your platform and etc.


  • For your integration, please make sure you have received the API user credentials for your account and the ApiKey for your terminal/s. If you do not have those parameters, please feel free to contact our on-boarding team at onboarding@splitit.com.

Which Integration Method to Choose?
Splitit allows you 4 ways to integrate with our platform:

Hosted Page
Fast and easy, the hosted solution allows you to let us deal with the transaction while using our pages. You can either redirect the shopper to our Payment Wizard or pop it up as an overlay layer on top of your page. This solution is also recommended if you are not PCI compliance.

Go to the Hosted Solution documentation

(For PCI Compliance systems)

We have built our Web API to be very simple and fast to integrate, requiring few days of effort, depending on the implementation.

This solution will allow you to control the shopper data insertion in your own checkout page, including the credit card number insertion and the approval page.

You might also use our pre-build approval page, hosted by Splitit. It will allow you to keep your shopper in the same UI environment and deal only with your shopper data.

Go to the Embedded Solution documentation

Virtual POS
(For retailers or support center)

Ideal for brick & mortar retailers, our Virtual POS does not require any integration. Through your Merchant Console, you are able to create a new installment plan, insert your customer details, and choose how many installments he/she wants.
