Internal API

This API is designed for internal use within Network Rail. It uses a simple authentication mechanism that does not link to a specific "user" within the system. It was created in response to a request to report into Power BI.

Base URL

https://nrsdb.uk/api/v1

Authentication

Registered users of the API will be issued with a key - all requests (other than this help URL) must pass this key as a Bearer token

Sample Code

Sample GET request

  const params = new URLSearchParams();
  params.append('property', value);

  const response = await fetch(`${url}?${params}`, {
    'credentials': 'same-origin',
    'headers': {
      'Authorization': `Bearer ${token}`
      'Accept': 'application/json',
      'Content-Type': 'application/json',
      'X-Requested-With': 'XMLHttpRequest'
    },
    'method': 'GET'
  });

Sample POST from a form element

const response = await fetch(url, {
  'body': formData,
  'credentials': 'same-origin',
  'headers': {
    'Authorization': `Bearer ${token}`
  },
  'method': 'POST'
});

NOTE: in my experience it is best not to set the 'Content-Type' header here
