  • create_connect_sessionCreate a setup page link

    A link to the service's setup page for one domain, to send to the customer. The page shows the DNS records, the live checks and, when the DNS provider supports it, one-step setup. Returns `url` (shown only now), `expires_at`, and `id` for revoke_connect_session. `ttl_seconds` is 300 to 86400 (default 24 hours); `app_name` and `return_url` (https) add a "Back to <app_name>" link. The link works for this domain only: give it only to the customer who owns the hostname.

  • create_domainRegister a customer's hostname

    Register a customer's exact subdomain (e.g. forms.acme.com) for a workspace. `reference` is your workspace id; it is returned on every request the edge forwards. Returns the domain with the two DNS records the customer must publish. Retrying with the same hostname and reference is safe.

  • delete_domainDelete a domain

    Stop serving a customer's hostname and delete it. It stops working at once. Confirm with the user first: their customer's address stops being served.

  • dns_instructionsDNS instructions

    The DNS records for a domain as text to give the customer, with help for each. Names the customer's DNS provider and its setup guide once the service has detected them.

  • get_domainGet a domain

    One domain with its status, DNS records and the four checks.

  • list_domainsList domains

    The application's domains, oldest first; filter by workspace `reference` or `status`. Pass `next_offset` from the result as `offset` for the next page.

  • list_webhooksList webhooks

    The application's webhook subscriptions (never their secrets).

  • recheck_domainCheck a domain again

    Run all checks again now, after the customer fixed DNS. At most once a minute per domain; the outcome shows on the next get_domain.

  • revoke_connect_sessionRevoke a setup page link

    End a setup page link now (`session_id` is the `id` create_connect_session returned). The customer's link stops working at once. Revoking it again is a no-op.
