# contractors.invitations.fixEmail

Fix the email a contractor was invited at and send a new invitation in one step, until they join the portal, with id, expectedRevision and email. Open invitations to the old address stop working and their link says it was replaced, and a new 7-day invitation is queued to the corrected address. The email must be unique in the organization and different from the current one; at most 6 invitations a day. Refused once they've joined.

Permissions: `accounting:read`, `accounting:write` · Roles: admin, finance · Idempotency key required · Send `expectedRevision` · Reaches outside Oatmilk (email or a provider)

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | string (ID) | Yes | The record's ID. |
| `expectedRevision` | integer | Yes | 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. |
| `email` | string (email) | Yes | An email address. at most 320 characters. |
| `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. 8–150 characters. |
