About GOV.UK Pay

Through Operate As, your agent, n8n workflow or code works in GOV.UK Pay with your client's own access. Your client pastes their API key from GOV.UK Pay once. We store it encrypted, so it never sits in an email or a shared doc. It comes with 10 ready-made tools for GOV.UK Pay's API, and the request tool reaches any endpoint they don't cover.

Common uses in Accounting
