If you're completely new to TrueLayer, our quickstart guides will help you start testing in sandbox, no coding knowledge required.
Before you start, download either the Postman or Insomnia REST API client. Our guides use collections: sets of preconfigured API requests with variables you can adjust to simplify testing and repeated requests.
Do this first.
This guide shows you how to get set up in Console. In Console you can set up your
client_secret. You need these to authorise your requests to any API. You can perform other tasks in Console, such as customising auth links, managing your merchant accounts, and more.
Make a test payment with the Payments API v3. It uses Insomnia to make signing requests simpler, so you can quickly experiment with and test the payments flow.
