# Send a verification code to a sender address

`POST /v1/verified-senders`

- Authentication: required (Bearer token)
- Required scope: `api.inboxes.manage`

Emails a six-digit code to the address in the body and records a
pending claim. Complete it with
`POST /v1/verified-senders/{id}/confirm`.

**This sends real email from SendOps' own mail service** — not from
your SES account — to whatever address you name. Rate-limited to five
starts an hour per user. Grant `api.inboxes.manage` with that in mind.

**Why bother.** An inbox whose `allowed_senders` are all verified is
`restricted`, and a restricted inbox is exempt from the mint quota and
the per-credential cap. Verifying one address is the difference between
three inboxes a day and an unmetered supply.

`202`, not `201`: the row exists but the address is not verified and
cannot be until somebody reads the mailbox.

Calling it again for the same address replaces the code and resets the
attempt counter, which is also how a claim locked by five wrong codes
is unlocked. The rate limit is what stops that being a way around the
lock.

**Requires a user-delegated token**, for the reason the list route
gives.

The code is never in a response, an error, or a log.

## Responses

### 202 — A code is on its way to the address; the claim is pending

Content type: `application/json`

```json
{
  "id": "00000000-0000-0000-0000-000000000000",
  "email": "string",
  "status": "pending",
  "code_expires_at": "2026-05-17T20:00:00Z",
  "verified_at": "2026-05-17T20:00:00Z",
  "created_at": "2026-05-17T20:00:00Z"
}
```

### 401 — Missing, malformed, or unknown API key

Content type: `application/problem+json`

```json
{
  "type": "https://example.com",
  "title": "string",
  "status": 0,
  "detail": "string",
  "code": "invalid_key",
  "request_id": "string",
  "retry_after": 0,
  "retention_days": 0,
  "scope": "string",
  "resource": "string",
  "errors": [

    "string"
  ]
}
```

### 403 — Either the credential lacks the required scope (`code: invalid_scope`), or it is bound to the `test` environment and this operation is irreversible (`code: test_environment_forbidden`). Branch on `code`: the first is fixed by granting the scope, the second only by using a live credential. See the "Live and test credentials" section of the API description.

### 409 — The mutation is rejected by a state rule rather than a bad request. The
`code` is `conflict`.

```json
{
  "type": "https://example.com",
  "title": "string",
  "status": 0,
  "detail": "string",
  "code": "invalid_key",
  "request_id": "string",
  "retry_after": 0,
  "retention_days": 0,
  "scope": "string",
  "resource": "string",
  "errors": [
    {
      "field": "string",
      "reason": "string"
    }
  ],
  "attribute_id": "00000000-0000-0000-0000-000000000000",
  "content_hash": "string",
  "differs": [
    "string"
  ]
}
```

### 422 — A query parameter, path value or body field failed validation.

The body is a `validation_failed` Problem. When the refusal is about a
reference — a segment key, template slug, topic or attribute name the
organization does not have — it additionally carries `validation_code`,
`field`, `line`/`column`, `missing`, `candidates` and `next_step`, so a
client can correct the call without a second round of guessing. See
`ValidationProblem`.

Content type: `application/problem+json`

```json
{
  "type": "https://example.com",
  "title": "string",
  "status": 0,
  "detail": "string",
  "code": "invalid_key",
  "request_id": "string",
  "retry_after": 0,
  "retention_days": 0,
  "scope": "string",
  "resource": "string",
  "errors": [

      "reason": "string"
    }
  ],
  "attribute_id": "00000000-0000-0000-0000-000000000000",
  "content_hash": "string",
  "differs": [

  "validation_code": "invalid_syntax",

### 500 — Unexpected server-side failure. The `code` is `internal_error`. The
`request_id` field can be quoted to SendOps support to investigate.
