REST and JSON
The LOOP API has been designed to fit closely in line with Government Digital Service (GDS) standards.
The endpoints have been implemented using a RESTful architecture. It makes use of HTTP verbs to indicate the action you are wanting to perform.
Safe methods (GET) will never alter data, whilst unsafe methods (POST, PUT and DELETE) will.
The entire API is designed to work with JSON, and expects all input to be sent as JSON (with exception to files). The following headers are expected to be sent with each request:
Content-Type: application/json Accept: application/json
