Context Variables and Methods Reference

A number of context variables and methods are available for use in webhook provider match scripts and webhook function scripts. View suggestions while editing the match script or function editing windows by typing Ctrl + Space. These variables and methods are described below.

Context Variables

If the webhook payload cannot be converted to JSON, it will be passed as a simple string

Accessing Map Values

Map Values can be accessed a number of ways. Here are a few common ones:

  • HTTP_HEADERS['header-key-with-dash']

  • PAYLOAD.get('key')
  • PAYLOAD.field1.field2
