I get this error message : <message>Warning: 299 - "Accessing API with invalid key"</message>
with any request I send through Postman, I also send the access token with it as a bearer token,
I am pretty sure the api and authorization are correct.
I use this URL to get the access token: https://www.upwork.com/ab/account-security/oauth2/authorize?response_type=token&client_id=${CLIENT_ID}&redirect_uri=${encodeURIComponent(REDIRECT_URI)}
and I send the auth token through Postman as here: enter image description here
update: turned our test APIs were shutdown by upwork, you have to use GraphQL as alternate
