Single Immediate Payments (SIP) v1

Token.io's Single Immediate Payments v1 API supports payment initiation for:

• Single Immediate Payments

• Future Dated Payments

Using Token.io's API, you can initiate account-to-account (A2A) payments via Open Banking using PSD2 directly from the user’s bank account. Before accessing an account, you must receive formal approval and consent from the user. A connection to the payer’s banking system is then required to access and debit the payment account through your payment instruction.

The integration options to initiate A2A payments vary depending on whether you use Token.io's Hosted Pages (HP) integration options or the API-only integration.

These integration options are detailed below:

• Hosted Pages (HP) integration – the TPP uses Token.io's HP to manage parts of the account-to-account payment initiation experience.

• API-only integration (./sip-v1-api) – the TPP owns the user experience including bank selection logic, collection of mandatory fields, and embedded and decoupled authentication methods.
