Common URL Parameters

The Common URL Parameter ?format is available in most Service Registry public API calls. It controls the line breaks and indenting in the JSON responses. This parameter is available on all Service Registry Public API calls. By default, these calls return JSON with a single space separating each elements and with no line breaks.

  • n—Terminate each element of the JSON response with a newline character.

  • w—Terminate each element of the JSON response with a newline/line feed.

  • t—Use the tab character instead of the space character for indenting.
