How to Send Authorization Token Using WSO2 API Manager

I recently got started with wso2 api manager. I managed to import an existing api which requires a bearer token to be included in the header as a way of authentication. I can not seem to find a way to include the bearer token in the API Manager therefore getting an 401 unauthorized error as a result. Can you help me resolve this Please. Thank you in advance.

I am still trying to send the bearer token using this.

Error Shown when adding the custom auth header

Solution

If you are asking how to consume an API, take a look at this and this documents.

curl -H "Authorization: Bearer <access-token>" -H "accept: application/json" "https://<server-IP>:<port>/pizzashack/1.0.0/menu" -k -v

If you want to pass the Bearer token to the backend, add the following config to <API-M_HOME>/repository/conf/deployment.toml.

[apim.oauth_config]
enable_outbound_auth_header = true

If you want to send a custom token, take a look at this.
