--- title: Registrar --- [Skip to content](#_top) [API Reference](https://developers.cloudflare.com/api) Copy Markdown Open in **Claude**Open in **ChatGPT**Open in **Cursor** --- **Copy Markdown****View as Markdown** # Registrar Registrar API for searching, checking, registering, and managing domains through Cloudflare Registrar. ## Prerequisites Before using this API, ensure: 1. **Cloudflare account** — the caller must have a valid Cloudflare account. 2. **Billing profile** — the account must have a billing profile with a valid, current default payment method (credit card or other accepted method). This cannot be set up via API — the account owner must configure billing at `https://dash.cloudflare.com/{account_id}/billing/payment-info` before calling `POST /registrations`. 3. **API authentication** — use an API token or API key with the appropriate Registrar permissions for the operations you are calling. ## Terminology: domain extension Throughout this API, “extension” refers to the domain extension part of a fully qualified domain name — the portion after the registrable label. For example, in `example.co.uk`, the extension is `co.uk` (not just `uk`). This covers both top-level domains like `com` and multi-level extensions like `co.uk`. This is distinct from other uses of the word “extension” (e.g., EPP extensions). ## Supported extensions This API supports programmatic registration for all extensions supported by the dashboard experience, with the following exceptions: `giving`, `mom`, `inc`, `lol`, `sh`, `link`, `cc`, `new` Cloudflare Registrar supports 400+ extensions in the dashboard. Extensions listed above can be registered at `https://dash.cloudflare.com/{account_id}/domains/registrations`. ## Typical workflow 1. **Search** — call `GET /domain-search?q={keyword}` to discover available domains. 2. **Check** — call `POST /domain-check` with candidate domains to verify real-time availability and pricing. 3. **Review the response** — if `registrable: false`, inspect `reason` to understand whether the domain is unavailable, the extension is not supported by this API, the extension is not supported by Cloudflare Registrar at all, or the extension’s registry has frozen new registrations. 4. **Handle premium domains** — if `tier: premium`, premium registration is not currently supported by this API. Surface the premium pricing to the user, but do not proceed to `POST /registrations` for that domain. 5. **Observe the registration schema** — call `GET /extensions/:extension_name` to discover the required values for registering this extension. 6. **Register** — call `POST /registrations` with the chosen domain name for supported non-premium registrations. 7. **Confirm completion** — if the response is `201 Created`, registration completed within the default timeout and no polling is needed. 8. **Poll when needed** — if the response is `202 Accepted`, poll `links.self` from the workflow response. 9. **Stop for user action** — if `state: action_required`, stop polling and surface `context.action` to the user. The workflow will not resolve on its own. 10. **Continue when blocked** — if `state: blocked`, continue polling and inform the user that a third party, such as the extension registry or losing registrar, is delaying progress. 11. **Review failures before retrying** — if `state: failed`, review `error.code` and `error.message`, then decide whether user action or a new Check call is needed. **All successful domain registrations are non-refundable.** Once the registration workflow completes with `state: succeeded`, the charge cannot be reversed. Confirm pricing and domain choice with the user before calling `POST /registrations`. ## Default behavior for mutating operations By default, mutating operations such as create and update hold the connection for a bounded, server-defined amount of time while the operation completes. In most cases, the response contains a completed workflow status and no polling is required. - **Completed within the synchronous wait window:** Returns `201` (create) or `200` (update) with a `workflow_status` where `state: succeeded` and `completed: true`. - **Still processing after the synchronous wait window:** Returns `202 Accepted` with a `workflow_status` where `completed: false`. Use the `links.self` URL to poll for completion. ## Non-blocking mode To receive an immediate `202 Accepted` response without waiting, send the `Prefer: respond-async` request header (RFC 7240). The server will acknowledge it with a `Preference-Applied: respond-async` response header. ## Polling When the response is `202`, poll the workflow status endpoint indicated by `links.self` in the response body until the workflow reaches a terminal state or requires user action. ##### [Search for available domains](https://developers.cloudflare.com/api/resources/registrar/methods/search) GET/accounts/{account\_id}/registrar/domain-search ##### [Check domain availability](https://developers.cloudflare.com/api/resources/registrar/methods/check) POST/accounts/{account\_id}/registrar/domain-check ##### [Check domain transfer eligibility](https://developers.cloudflare.com/api/resources/registrar/methods/transfer_check) POST/accounts/{account\_id}/registrar/domain-transfer-check ##### ModelsExpand Collapse
