# provisionIgaServiceItemByRequest

Provision the IGA access request for a service request.

Request-keyed variant of `provisionIgaServiceItem`: resolves the service-item-instance from
the service request (SER) id and provisions it. The grant recipient / IdP-group subject is
the instance's owner (the requester), not the caller.

## Parameters

| Name        | Type    | Required | Description                                                                                                |
| ----------- | ------- | -------- | ---------------------------------------------------------------------------------------------------------- |
| `requestId` | string  | Yes      | Service request display id (e.g. SRQ-123) to provision                                                     |
| `is_mock`   | boolean | No       | Internal. Mock/PoC tenant flag — skips IdP calls and only creates the grant. Omit for normal provisioning. |
