<Badge color="yellow">BETA endpoint</Badge>

This is a work-in-progress documentation of a BETA endpoint. The parameters, fields, request and response bodies, and other data may subject to change. If you want to share feedback or improvements, contact [Voucherify support](https://www.voucherify.io/contact-support) or your Technical Account Manager.

</Warning>

Assigns and/or unassigns rewards to/from a program in a single batch.
Unassign operations are processed before assign operations. Each reward to assign
must include its `stock` configuration. In strict mode (default) missing rewards
or missing assignments cause the whole batch to fail (`404 Not Found`).

## Path parameters

- `programId` string, required

## Request body

- ProgramRewardBatchRequest — Batch of reward assignment operations. `unassign` operations are processed before `assign` operations. Duplicate ids within a batch are rejected.
  - `assign` ProgramRewardAssignItem[], nullable — Rewards to assign, each with its stock configuration.
    - `id` string, required — Unique reward identifier.
    - `stock` ProgramRewardAssignmentStock, required — Reward stock configuration. When `type` is `UNLIMITED`, `limited` must not be provided. When `type` is `LIMITED`, `limited` is required.
      - `type` 'UNLIMITED' | 'LIMITED', required — Stock type.
      - `limited` ProgramRewardAssignmentStockLimited — Limited stock configuration.
        - `quantity` integer, required — Available stock quantity.
  - `unassign` ProgramRewardUnassignItem[], nullable — Rewards to unassign.
    - `id` string, required — Unique reward identifier.
