The Composer inside Fiddler Everywhere allows you to create requests to APIs.
Requests that are made to local and online APIs enable you to check and debug various endpoints, inspect and analyze requests and responses, and retrieve and receive data quickly.
To create an API request:
Select an appropriate HTTP method and enter the endpoint URL. The Composer supports the GET, POST, PUT, DELETE, TRACE, SEARCH, and PROPFIND methods and also allows you to change the version of the HTTP protocol with the drop-down menu to the left of the Execute button.
(Optional) If required, enter additional headers, parameters, and body. For example, common scenarios are to enter an authorization header, a Content-type header, or custom body data.
By default, the Fiddler Everywhere client will add a User-Agent header with the Fiddler Everywhere value. This header lets servers and network peers identify the application, the operating system, the vendor, and/or the version of the requesting user agent.
To inspect the request that will be sent to the server in detail, use the read-only Raw view.
To send the composed API request, click Execute.
Inspect the result in the Response inspector tab of the Composer. Like the inspectors for the Live Traffic tab, the Response inspector provides multiple views such as Headers, Raw, JSON, and so on.
(Optional) You can save the request by clicking the Save button located to the right of Execute. Saved requests are loaded as a collection in the Requests list and can be reused or shared with collaborators.
