# connectors.wise.signingKey.create

Create a signing key for Wise's strong customer authentication from the administrator dashboard. The private half is saved encrypted with the Wise credential; only the public half is returned, to add in Wise (Settings › API tokens › Manage public keys). A saved key is replaced only with replace true, because payouts sign with the same key. Requires the credential's expectedRevision and idempotencyKey.

`POST /api/v1/accounting/connectors.wise.signingKey.create`

Permissions: `accounting:read`, `accounting:write`, `accounting:admin` · Roles: admin · Idempotency key required · Send `expectedRevision`

Not available over MCP: It replaces a provider secret that payouts also sign with.

## Fields

| Field | Type | Required | Notes |
| --- | --- | --- | --- |
| `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. |
| `replace` | boolean |  |  |
| `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. |
