Getting Started With Our API

Open a sandbox test account with UNIPaaS

You can create a test account in 1 min!

Create your account

The test account gives you a free unlimited account with all features and capabilities - including payouts, vendor account management, and a fully functional portal you can use to train your team.

The test account will always be available, even after opening your live account. You can switch back to test mode using this toggle.



We provide two different URLs for making API calls: Test Sandbox or Live environments. These two environments are separate and share no information.

The API credentials are completely different between environments.
For testing, please use the Sandbox URL. When you're ready to process live transactions, use the Live URL.

API Idempotency

To make sure an API request is not executed multiple times due to internal or any other error, our API supports idempotent requests. This means that the same request can be applied multiple times without changing the result beyond the initial request.
For example: Sending the same transaction request multiple times will create a single transaction, and will not result in multiple transactions.

To be able to use the idempotency mechanism, add requestId: <id> to POST request header.
All request ids will be valid during 24 hours.

Find API keys in the Portal

Once you have opened a Sandbox account you can find your keys here:
Note that you currently need to use the Private Key only.
