Introduction

Insomnia is an open-source cross-platform RESTful API client, currently maintained by Kong, with a simple to use GUI and a rich set of functionality.

Quick Start With Insomnia

To help you get started, we prepared a simple tutorial for calling our APIs using the Insomnia REST client. The tutorial will show how you can:

1. Download and install an Insomnia REST Client.
2. Import default configuration and customize it, including the PSD2 certificate.
3. Create your application and manage applications.
4. Go through the OAuth 2.0 handshake to obtain an access token.
5. Call our API, for example, to obtain the payment account list.

Downloading Insomnia

You can download and install Insomnia at the vendor website: https://insomnia.rest/

After downloading the Insomnia application, install it as you usually do on your system.

Installing Access Token Interception Plugin

To simplify workflow, you can optionally install the insomnia-plugin-accesstoken plugin. This plugin automates intercepting the OAuth 2.0 Access Token and storing it in the environment variable. To install the plugin:

1. Open "Insomnia > Preferences" and select the "Plugins" tab.
2. Type insomnia-plugin-accesstoken into the npm-package-name field.
3. Click "Install Plugin" button.

In case you decide not to install the plugin, you can always edit the OAUTH_ACCESS_TOKEN environmental variable manually in environment settings.
