Question:
When integrating with the chatflow API and calling the chat-messages endpoint, we include custom headers x-auth-value and x-emp-no in the HTTP request. How can these header values be accessed and retrieved within the chatflow system?

Example Request:
curl -X POST 'http://xx.xx.xx.xx/v1/chat-messages'
--header 'Authorization: Bearer {api_key}'
--header 'Content-Type: application/json'
--header 'x-auth-value: xxxxc4ee05c690exxx74fc0b7xxxxda'
--header 'x-emp-no: 123456'
--data-raw '{
"inputs": {},
"query": "What are the specs of the iPhone 13 Pro Max?",
"response_mode": "streaming",
"conversation_id": "",
"user": "abc-123",
"files": [
]
}'

You can access custom HTTP headers like x-auth-value and x-emp-no in the /v1/chat-messages endpoint by using Flask's request object. In the Dify backend, the chat-messages endpoint is implemented with Flask, and you can retrieve these headers in the endpoint handler with:

from flask import request

x_auth_value = request.headers.get('x-auth-value')
x_emp_no = request.headers.get('x-emp-no')

You can add this code inside the post method of the ChatApi class (located in api/controllers/service_api/app/completion.py). If you want to pass these values further into your business logic, include them in the args dictionary or as function parameters as needed. This approach is already used for other headers, such as extracting trace IDs in the same endpoint, so it fits the existing pattern of header handling in Dify’s chatflow system
see implementation reference.
