Required arguments to methods must be passed via the HTTP request body in json format. For example when calling the fetch() method, we must pass a spec parameter. This can be passed with a json formatted payload like this:
{{
| Header | Description | Possible Values |
|---|---|---|
| Accept | Indicates the media types which are acceptable for the response | application/json application/xml (default) |
| Content-Type | Indicates the media type of the entity-body sent to the recipient | application/json |
| Request-Method | Indicates the desired action to be performed for the resource | POST |
| Authorization | Username and Password |
