# Assign a facility credentialing workflow to a user

`POST /facility-credentialing-workflows/{id}/assignments`

Creates an assignment record for the specified facility credentialing workflow, associating it with the given user and appending an entry to the assignment history. **When to use:** Use to assign (or reassign) a single workflow to one user. To assign multiple workflows at once, use `POST /facility-credentialing-workflows/assignments`. **Preconditions:** The caller must hold the `FACILITY_CREDENTIALING_WORKFLOW_ASSIGN` or `ASSIGN_SELF` permission. The target user must have the required permissions to be assigned; if not, `422 Unprocessable Entity` is returned — select a different assignee or ensure the target user's permissions are elevated. **Side effects:** An assignment history entry (`FacilityAssignmentHistoryResponse`) is created. **Returns:** `201 Created` with the new `FacilityAssignmentHistoryResponse` in the body.
