# Add a domain to prove. It starts as pending, with its TXT record.

`POST /v1/organizations/current/domains`

## Request

- Base URL: `https://api.50heads.com`
- URL: `https://api.50heads.com/v1/organizations/current/domains`
- Auth: one of:
  - HTTP bearer
  - OAuth 2 (authorization code, authorization URL `https://auth.50heads.com/authorize`, token URL `https://auth.50heads.com/token`; client credentials, token URL `https://auth.50heads.com/token`, scopes: `organization:write`)

Organization admins only (403 `organization_admin_required`). Signed in, with a fresh proof in the `x-50h-reauth` header (401 `reauth_required`); with an API key, a connected app or a service account, with the scope named here and no proof, where the organization has machine identities (otherwise 403 `session_required`). The key's or app's person must be an organization admin. Every change is written to the organization's audit, with who made it (a person, a key, an app or a service account). The exact domain only: example.com covers addresses @example.com, not @mail.example.com and never @evil-example.com. Public suffixes (co.uk), free email providers and disposable email domains are refused with `domain_not_allowed`. Up to 20 domains.

## Other responses

- `400`: The request is not valid; `error.details.validation` lists the fixes.
- `401`: No key or token, or it expired or was revoked.
- `403`: The key or token lacks the scope (`insufficient_scope`), or the action is not allowed.
- `429`: Too many requests; wait for Retry-After.
