<Warning>

<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 card definitions to/from a program in a single batch.
Unassign operations are processed before assign operations.
The program must be in `DRAFT` status - otherwise the request is rejected with
`423 Locked` (key `non_draft_program`). In strict mode (default) missing card
definitions, inactive card definitions or missing assignments cause the whole
batch to fail.

## Path parameters

- `id` string, required

## Request body

- ProgramCardDefinitionBatchRequest — Batch of card definition assignment operations. `unassign` operations are processed before `assign` operations. Duplicate ids within a batch are rejected.
  - `assign` ProgramCardDefinitionAssignItem[], nullable — Card definitions to assign.
    - `id` string, required — Unique card definition identifier.
  - `unassign` ProgramCardDefinitionUnassignItem[], nullable — Card definitions to unassign.
    - `id` string, required — Unique card definition identifier.

## Response `200`

Batch processing result.
