All RHRS requests are secured via BASIC HTTP authentication over HTTPS.

Request Type

At this point in time, all requests use the GET method.

Content Type

The RHRS API can return data in one of three formats depending on the content type that is supplied as part of the request.

  • application/xml
  • application/json
  • image/*

The image content type is only applicable to the /request/titles/ISBN resource as it will return the cover image.
