Define a REST message HTTP header

Define an HTTP header for a REST message or HTTP method to send that header with REST requests.

Before you begin

Role required: web_service_admin

About this task

You can specify an HTTP header for a REST message, or for an HTTP method. Headers defined for a REST message apply to all HTTP methods for that REST message. If you specify the same header for both a REST message and a child HTTP method, the value defined for the HTTP method overrides the value from the parent REST message.


  1. Navigate to System Web Services > REST Message.
  2. Select a REST message.
  3. (Optional) To specify a header for an HTTP method instead of the REST message, in the HTTP Method related list, select an HTTP method.
  4. Select the HTTP Request tab.
  5. In the HTTP Headers embedded list, click Insert a new row.
  6. Enter the name of the header, such as Content-Type or Accept.
    Supported headers depend on the REST web service provider you want to connect to. Refer to the documentation for your web service provider to identify which headers are valid or required.
  7. Click on the Value field for the new row and enter the value you want to assign this header.
    You can use a variable in the format ${variable} instead of a static value. You can assign a value to the variable when sending a REST request.
  8. Click Update.
