# Bulk-assign or unassign facility credentialing workflows

`POST /facility-credentialing-workflows/assignments`

Assigns one or more facility credentialing workflows to a set of users in a single call, distributing workflows evenly across the supplied user IDs using round-robin. **When to use:** Use to reassign a batch of workflows or to clear all assignees at once. To assign a single workflow, use `POST /facility-credentialing-workflows/{id}/assignments`. **Key behaviors:** * Existing assignees are replaced by the new assignment — this is not additive. * To unassign all workflows in the batch, pass an empty array for `assignedTo`. * Each workflow is processed independently; the response contains separate `successful` and `failed` arrays — inspect both. * * **Returns:** `200 OK` with bulk-result arrays listing which workflow IDs succeeded and which failed.

## Headers

- `tenant-id` string, required

## Request body

- BulkCreateFacilityAssignmentRequest — Request to create assignments for multiple facility credentialing workflows
  - `workflowIds` string[] — List of facility credentialing workflow IDs to assign. Required when isSelectAll is false. Ignored when isSelectAll is true (workflow IDs will be fetched using the filter).
  - `assignedTo` string[], required — List of user IDs to assign workflows to. Workflows will be evenly distributed across these users. If empty array, all workflows will be unassigned (assignedTo set to null).
  - `reason` string — Optional reason for the assignment
  - `filter` string — Filter criteria as JSON string (URL encoded). Used to fetch workflow IDs when isSelectAll is true. See GET /facility-credentialing-workflows endpoint documentation for filter format.
  - `isSelectAll` boolean — If true, fetch all workflow IDs matching the filter criteria instead of using workflowIds. When true, filter parameter is required and workflowIds will be ignored.
