How to pass two authorization headers to curl POST request - rest

Question

I'm accessing a rest api.
I have to do POST. The webservice is hosted behind the basic authentication.
To access the given endpoint I have to also send an authorization header.
case 1:
curl GET http://username:password#example.com/endpoint1 => works
case 2:
curl GET http://#example.com/endpoint1 -H "Authorization: Basic base64_encode(username:password)" => works
case 3:
curl POST http://#example.com/endpoint2 -H "Authorization: Basic base64_encode(username:password), Basic another_auth_token" => does not work
case 4:
curl POST http://username:password#example.com/endpoint2 -H "Authorization: Basic another_auth_token" => does not work
Also tried using php curl curl_setopt($ch, CURLOPT_USERPWD, 'username:password') and it didn't work.
Tried adding headers, Content-Type: application/json and application/x-www-form-urlencoded and it didn't work.
I need curl POST with the two authorization headers to work.
Any pointers what could be missing?

Answer 1

Just pass '-H Authorization' twice:
curl -X POST http://example.com/endpoint2 \
-H "Authorization: Basic base64_encode_username_colo_password" \
-H "Authorization: Basic another_auth_token"
I get:
POST / HTTP/1.1
Host: localhost:10101
User-Agent: curl/7.47.0
Accept: */*
Authorization: Basic base64_encode_username_colo_password
Authorization: Basic another_auth_token
Keep in mind, though, that the server (and downstream servers as well) has to be able to deal with multiple authorization headers.

curl -X POST
'https://api.amazon / shopify or "your URL"/'
-H 'Authorization: Bearer {token}' // or/AND your USER KEY and PASS in Base 64
-H 'Accept: application/json'
-H 'Content-Type: application/json'
for body parameter in CURL You should use -d'{your body in json}after the last Header param.(-H)
