Verified steps
Create an employee account in the Envoy dashboard, assign it a Global Admin role, and disable 'Show employee as a host on the Visitors Kiosk'
In the Dev Dashboard, create a new integration and add the required API scopes to obtain a client ID and secret
POST to https://api.envoy.com/oauth2/token with a Basic auth header (base64 client_id:client_secret), grant_type=password, and the user's email/password to receive an access_token and refresh_token
Store the access token (expires in 86400 seconds) and use the refresh_token to get a new one instead of re-authenticating with credentials
POST to https://api.envoy.com/v1/invites with the Bearer token to create an invite, ensuring the flow and host/employee correspond to the same location
Known gotchas
The password grant type is documented for private, single-company apps only; apps distributed to other Envoy customers must use a different OAuth flow
Invite creation can fail if the flow and employee/host don't match the target location, even though the request otherwise looks valid
Access tokens expire after 24 hours — use the 30-day refresh token rather than repeating the password grant
