# merchants.confirm

Confirm what Oatmilk filled in for a merchant, optionally correcting displayName, websiteDomain, description, industry or kind in edits. Confirmed and corrected fields belong to the person and are never overwritten by a later lookup. Needs the merchant key and an idempotency key; pass expectedRevision from merchants.get to detect changes.

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `key` | string | Yes | 1–120 characters. |
| `expectedRevision` | integer |  | The record's current revision, from the last time you read it. If someone changed the record since, the request is refused with a conflict so you can reload and check before trying again. at most 9007199254740991; greater than 0. |
| `edits` | object |  | No other fields. |
| `edits.displayName` | string |  | 1–200 characters. |
| `edits.websiteDomain` | string |  | at most 253 characters; Matches ^[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?(\.[a-z0-9]([a-z0-9-]{0,61}[a-z0-9])?)+$. |
| `edits.description` | string |  | A short description. 1–240 characters. |
| `edits.industry` | string |  | 1–80 characters. |
| `edits.kind` | enum |  | Which kind of record or job this is. One of: `unknown`, `business`, `person`, `government`, `financial`. |
| `idempotencyKey` | string | Yes | Any unique text you generate once per intended change, so a retried request only happens once. Send it as the Idempotency-Key header instead if you prefer; if you send both they must match. 8–200 characters. |
