Flowaccount Authentication
FlowAccount Open API uses OAuth 2.0 client credentials. A registered integration exchanges its client_id + client_secret at the token endpoint ({base}/token) with grant_type=client_credentials and scope=flowaccount-api to obtain a bearer access token, then sends it as `Authorization: Bearer
FlowAccount secures its APIs with oauth2 and http across 2 declared security schemes, as derived from its OpenAPI definitions. OAuth 2.0 is offered via the clientCredentials flow(s).
