Checkin api returns 401

We are integrating open charge map API in our project.

I already integrated all of the endpoints but comment/check-in api returns 401(unauthorized) error even though I sent the api key as X-API-Key in the header.

I am not sure what the issue is.

Thanks, as discussed via email you need to present an Authorization: Bearer <token> http header with an access token derived from signing in an OCM user.
