Where to Find Your Credentials

Navigate to the Developer section of the EximPe Dashboard. You’ll find:
  • Client ID
  • Client Secret
These are required to authenticate your API calls.

​
API Version Header

All API requests must include the X-API-Version header to specify which version of the API you’re using:
  • Version 2.0: X-API-Version: 2.0.0
  • Version 1.0: X-API-Version: 1.0.0
This header ensures your integration uses the correct API version and helps maintain backward compatibility.

​
If You Are a Payment Service Provider (PSP)

Receiving payments on behalf of your merchants:
  1. Add a Merchant
    • Before you can make API calls on behalf of a merchant, you must first add them.
    • Sandbox: A dummy merchant is automatically created upon signup.
    • Refer to the Adding Merchants guide for details.
  2. Activate the Merchant
    • In Sandbox, merchants are activated instantly.
    • In Production, merchant activation follows due diligence in compliance with RBI guidelines.
  3. Retrieve the merchant_id
    Once a merchant is activated, you’ll receive their merchant_id, which, along with the client_id and client_secret, is required to authenticate and validate API requests.
In Production, you will receive Credentials (client_id and client_secret) for secure API usage upon Account Activation.
For PSPs, payments can only be initiated upon successful activation of the corresponding merchant.
