Payments overview

Our guides aim to explain relevant domain concepts, introduce the API entities that you will be using to construct payment flows, and provide examples to help you get up and running quickly with your payments integration.

The general structure of the docs starts with concepts and entities near the top, moving in to specific examples and practical guides further down.

Our APIs support multiple UK payment schemes, each serving different purposes:

• Faster Payments - Near real-time payments up to £1 million, typically settling within seconds or minutes
• Book Transfers - Internal transfers between accounts within the same organization, occurring instantly
• Bacs Direct Credits - UK's standard payment system for bulk credit payments, settling in 3 working days (inbound payments only)
• Bacs Direct Debits - coming soon
• CHAPS - High-value, same-day payment system for time-critical transactions with no upper limit (inbound payments only)
