Utilize RapNet Instant Inventory (premium service) with JSON

Introduction
Once you have set up your RapNet Instant Inventory (was RapLink) through RapNet, you can intergrate this in your website using JSON combined with HTTP requests. Each request and response will have two sections: The 'header' and 'body'. The header section will contain meta data, such as your username and password in the request, and in the response this will contain a result code of the operation. All available methods have the same header parameters. The body section contains the parameters and data that are send to and from. The parameters differ per request and response.

General usage information
  • Authentication - each request should have a username and password in the header section
  • All requests should go to a URL starting with HTTPS
  • All data should be send using POST
  • Send request as Content-Type: application/x-www-form-urlencoded
  • URL-Encode the request.
  • Optional values can be omitted or left blank.
  • the response will always contain an 'error_code' field. Value 0 means the operation succeeded.
