# Verify Domain Claim

> POST /domains/:domain_id/claim/verify — trigger DNS verification for a domain claim.

`POST /domains/:domain_id/claim/verify`

Starts an **asynchronous verification process** for a domain claim. MailBlastr checks the claim’s TXT record and, once it resolves, transfers the domain to your account. Add the TXT record returned by [Claim Domain](https://www.mailblastr.com/docs/api/domains-claim) before calling this, then poll [Get Domain Claim](https://www.mailblastr.com/docs/api/domains-get-claim) to follow the `status`.

> **Note:** After the claim completes, the domain is transferred to your account as a **brand-new domain with its own DKIM keys** — the previous account’s DNS records can’t be reused. Fetch it with [Retrieve a domain](https://www.mailblastr.com/docs/api/domains-get), publish the new DKIM record(s), then run [Verify a domain](https://www.mailblastr.com/docs/api/domains-verify) to finish setup before sending.

**Path parameters**

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `domain_id` | string | Yes | The placeholder domain id returned when the claim was created. |
