Our APIs support two fundamentally different inbound payment workflows

PayID

Send a Payment Request, which is exactly as it sounds: you request your customer to make a payment to you and your customer initiates the payment.

See PaymentRequest APIs

PayTo with Payment Agreements

Obtain an Agreement from your customer to collect payments automatically from their account and then send a Payment Initiation Request each time you are owed a payment to collect funds from their bank account.

You can follow the PayTo Integration Guide to get an idea on how to achieve the most basic flow. For more detailed information about the capabilities you can see PaymentAgreement APIs and PaymentInitiation APIs
