A request over the limit gets a `429` response whose `Retry-After` header gives the wait in seconds. ## Pagination Most list endpoints return paginated results. Use the `page` and `page_size` query parameters (at most 100 results per page). The response carries `count`, `next`, `previous`, `page`, `page_size`, `total_pages` and the `results` themselves. ## Error Handling The API uses standard HTTP status codes: - `200` Success - `201` Created - `204` No Content - `400` Bad Request - `401` Unauthorized - `403` Forbidden - `404` Not Found - `409` Conflict - `429` Too Many Requests - `500` Internal Server Error - `503` Service Unavailable Error responses carry a JSON body with `detail`, a human-readable message, and `code`, a stable machine-readable error code. Some errors add `context` with structured details, and `error` repeats `detail` for older clients. A request whose fields fail validation gets a `400` whose body maps each invalid field to its list of messages. A few older endpoints still answer with `error` alone. servers: - url: https://api.onetsolutions.net description: Production security: [] tags: - name: Authentication description: >- Login, passwordless authentication, MFA, OAuth providers, and token management. - name: Organizations description: >- Organization management, members, roles, modules, audit logs, and notification settings. - name: Projects description: Project management, team members, and project-scoped resources. - name: Compute description: >- Cloud instances, volumes, snapshots, backups, VPCs, firewalls, SSH keys, uptime monitors, and instance tasks. - name: Billing description: >- Shopping cart, orders, invoices, payments, payment methods, gateways, promo codes, and balance management. - name: Domains description: >- Domain availability, registration, transfers, DNS zones, DNS records, and TLD information. - name: Web Hosting description: >- cPanel-based web hosting, emails, databases, subdomains, FTP accounts, addon domains, and SSL certificates. paths: /v1/organizations/{organization_id}/projects/{project_id}/dns-zones/{id}/email-routing/catch-all: put: tags: - Domains summary: '[Email Routing] Update the catch-all' description: >- Decide what happens to mail sent to an address of the zone's domain that no rule matches: forward it to a verified destination (`destination_id` required) or drop it. operationId: update_dns_zone_email_routing_catch_all parameters: - in: path name: id schema: type: string description: The unique identifier (UUID) of the DNS zone required: true - in: path name: organization_id schema: type: string format: uuid required: true - in: path name: project_id schema: type: string format: uuid required: true requestBody: content: application/json: schema: $ref: '#/components/schemas/EmailRoutingCatchAllUpdate' required: true responses: '200': content: application/json: schema: $ref: '#/components/schemas/EmailRoutingCatchAll' description: Catch-all after the change '400': description: >- Invalid payload, The destination is not one of the organization's destinations (code: email_routing_destination_invalid) or is not verified yet (code: email_routing_destination_unverified), or The zone is not provisioned yet (code: dns_zone_not_provisioned), Cloudflare has not activated it yet because the domain still points elsewhere (code: dns_zone_not_active), or the operation failed (code: domain_operation_failed) '401': description: Authentication credentials were not provided or are invalid '403': description: You do not have permission to perform this action on this DNS zone '404': description: DNS zone not found or does not belong to the specified project '409': description: >- The zone belongs to your own Cloudflare account: manage email routing in its dashboard (code: zone_managed_in_client_account) '503': description: The DNS provider is unavailable.
