# Create assignments for multiple credentialing workflows

`POST /credentialing-workflows/assignments`

Creates assignments for multiple credentialing workflows in a single operation. Workflows are evenly distributed across the provided user IDs using round-robin distribution. Each workflow is processed independently, and results include both successful and failed assignments.

## Headers

- `tenant-id` string, required

## Request body

- BulkCreateAssignmentRequest — Request to create assignments for multiple credentialing workflows
  - `workflowIds` string[] — List of 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 /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.
