This is a short guide on how to set up Postman.
To import a collection, select Collections > Import > Link and enter the following link https://ob.nordigen.com/api/swagger.json.
When importing, set Schema for both Request parameter generation and Response parameter generation under Advanced Options.
After importing, you should have a new collection named "Nordigen Account Information Services API" and a new API defined.
Head to Collections, click "Nordigen Account Information Services API", and do the following:
Bearer YOUR_TOKEN. Since all requests inherit the security settings from the parent, they will use the token that you've configured here. Save the settings.
Now your Postman is set up and you can continue instructions from Quickstart Guide.
