API Upgrades

Sandbox Testing Environment

We highly recommend starting with the UInterfaceV2 Testing Environment to test the upgraded Payment Gateway and its features before switching to the Production Environment

Follow the following steps to upgrade your current UInterfaceV1 to the latest UInterface V2 Sandbox Testing Environment.

Update your code with reference to the sample code provided here in order to create a payment request.
Update your payment request API endpoint from
https://api.upayments.com/test-payment to
https://sandboxapi.upayments.com/api/v1/
Test Authorization Token (API Key) : jtest123 (same as in v1)
Token for Authorization Header (White Labeled API Key): e66a94d579cf75fba327ff716ad68c53aae11528

The old APIs endpoints must be replaced with new new API endpoints given below

Testing your Upgrades

After replacing all V1 APIs with UInterfaceV2 APIs, you can start Testing using the Sandbox Environment.

This Environment facilitates testing the upgrade without requiring real payments or charges. This environment has the same behavior as the Production Environment, including the creation of genuine objects.

Test API Keys can be used for this purpose, along with Test Card details.
