doDomain is domain-connect-as-a-service: it gives a product a guided flow for pointing a customer's own domain at that product, and handles the DNS records, verification, and certificates behind it. The doDomain plugin lets ChatGPT drive that work from your account: check a domain's current DNS state, list the apps configured on your team, list existing domain connections, create a new connect session for a customer, look up a session you already started, verify a session once the records are in place, and… …Connected Apps page in the dashboard.
