http_call>: Call workflow fetched by HTTP¶
http_call> operator makes a HTTP request, parse response body as workflow, and embeds it as a subtask. The operator is similar to call> operator. The difference is that another workflow is fetched from HTTP.
This operator parses response body based on returned Content-Type header. Content-Type must be set and following values are supported:
application/json: Parse the response as JSON.
application/x-yaml: Use the returned body as-is.
If appropriate Content-Type header is not returned, use content_type_override option.
The URI of the HTTP request.
content_type_override: application/x-yaml or application/json
Overrides Content-Type response header returned from the server. This option is useful when the server doesn’t return an appropriate Content-Type but returns a generic value such as text/plain or application/octet-stream.
