  3. Register an application

    Before you can use an API you have to register your application. When you register an application, the application is assigned a unique client ID and client secret. You must use the client ID when you call an API that requires you to identify your application by using a client ID, or a client ID and client secret. Check the API description for the details.

  4. Select a plan

    Now that your application is registered, you need to subscribe to a plan. The plan determines the number of API calls that your application can make. Some plans are free and no approval is required, some require approval, and some require approval and a monthly subscription. Think about what you need and choose the most suitable plan.

  5. Create a sandbox

    Since you selected a plan you will be able to invoke APIS, but first you need to create a new sandbox.
    All products have details about how to create a new sandbox.

  6. Invoke APIS

    There are multiple ways to invoke APIS.

    Using developers portal
    Postman
    Any other tool or custom application

    A list of users has been created to simulate multiple users as shown below. User must use the users as described below in order to authenticate via the OAuth2 flow as well to create consents, access accounts and initiate payments.

    After authenticating using the above username and password, an OTP code is required in order to complete the OAuth2 flow as well the SCA process which is required when creating a new consent or a payment initiation is made.

    The OTP code is 123456

    The Sandbox data are static, therefore after a payment initiation is made, that transaction is not stored and the balance is not reduced.
