Collections

Our collections for REST API clients are the quickest way to get started with our APIs. Each collection includes preconfigured environments, variables, and requests.

Before you start

• To use the collections you need a client_id and client_secret, which you can download from Console.

• You must download and install Postman or Insomnia to use the collections.

Payments API v3

The Payments API v3 collection contains requests for you to test payments, refunds, merchant accounts, payouts, and mandates.

The Payments API v3 collection requires Insomnia, as it supports request signing.

You need to generate public and private keys and install the TrueLayer Insomnia plugin to use this collection.

Click this Run in Insomnia button to download the Payments API v3 Insomnia collection.

Alternatively, download the Payments API v3 Insomnia collection from GitHub.

📘

When you download the Insomnia collection, you can choose to add it to an existing collection, or to create a new file.

If you create a new file, Insomnia creates a 'document'. In a document, ensure you select the Debug tab at the top of the screen in Insomnia to view the sample requests.

Data and Verification API

This collection contains requests for you to test data and account information, connections, and verification.
