Get access token
Use your client_id and password to get an access token.
This call needs only the x-api-key header. It is the one endpoint that does not need a bearer token.
The token arrives in data.access_token. Send it as Authorization: Bearer <access_token> on every other call, together with x-api-key.
data.expires_in is the token’s life in seconds. There is no refresh token: when the token expires, or when a call answers 401, call this endpoint again.
Save the token and reuse it until it is close to expiry. Do not log in before every request.
See the Authentication guide for more detail.
