</Info>

Assigns and/or unassigns tier structures to/from a program in a single batch.
Unassign operations are processed before assign operations. Unassigning is only
allowed while the program is in `DRAFT` status - otherwise the request is rejected
with `423 Locked` (key `non_draft_program`). A program can have at most one tier
structure assigned. In strict mode (default) missing tier structures, inactive tier
structures or missing assignments cause the whole batch to fail.

## Path parameters

- `id` string, required

## Request body

- ProgramTierStructureBatchRequest — Batch of tier structure assignment operations. `unassign` operations are processed before `assign` operations. Duplicate ids within a batch are rejected.
  - `assign` ProgramTierStructureAssignItem[], nullable — Tier structures to assign.
    - `id` string, required — Unique tier structure identifier.
  - `unassign` ProgramTierStructureUnassignItem[], nullable — Tier structures to unassign.
    - `id` string, required — Unique tier structure identifier.

## Response `200`

Batch processing result.

- ProgramTierStructureBatchResponse — Result of a tier structure assignment batch. Keys are null when the corresponding operation list was not provided.
  - `assigned` ProgramTierStructureAssignment[], nullable — Assignments created by the batch, or `null` when no assign operations were requested.
    - `tier_structure_id` string — Unique tier structure identifier.
    - `created_at` string, date-time — Assignment creation timestamp (ISO 8601).
    - `object` 'program_tier_structure' — Object type marker.
  - `unassigned` ProgramTierStructureAssignment[], nullable — Assignments removed by the batch, or `null` when no unassign operations were requested.
    - `tier_structure_id` string — Unique tier structure identifier.
    - `created_at` string, date-time — Assignment creation timestamp (ISO 8601).
    - `object` 'program_tier_structure' — Object type marker.

## Other responses

- `400` — Validation error - request body or query parameters failed validation, or the operation is not allowed in the current resource state.
- `404` — Resource not found.
- `409` — Conflict - e.g. duplicate resource or invalid state transition.
- `423` — Resource locked - a related resource is in a state that prevents this operation.
- `500` — Internal server error.
