Hi!
This is a basic function for some devices, doesnt need to be enable.
No in all the family CE 6800 is support it, or in all the VRP Versions,
Plese check the Licensing Requirements and Limitations for the OPS from your device and VRP to ensure it is support it
The standard HTTP request and response include the HTTP header and HTTP packet. The format of the HTTP packet is described in the Content-Type field of the HTTP header. You can specify the format of the response packet supported by the client in the Accept field. Currently the API supports only the XML format. Therefore, specify application/xml for the Content-Type and Accept field values.
Currently, the OPS integrates the Python running environment and can run Python scripts. In a Python script, methods of sending HTTP requests to the system need to be defined based on open RESTful APIs. When the Python script runs, HTTP requests are sent to the system to implement system management.
Please verify in the documentation the part:
Configuration -> Device Management Configuration Guide -> OPS Configuration

Have a nice day!
