`GET /accounting/performance-obligations/{id}/products`

Read-only: Reads and returns; changes nothing.

Lists a performance obligation's products. This endpoint doesn't follow the standard collection rules in Pagination and querying.

Page through the results with `pageSize` and `cursor`, not `page[size]` and `page[cursor]`. A pageSize below 1 is treated as 1. The response lists the records in `data.items` and the next page's cursor in `data.pagination.nextCursor`. The endpoint takes no filters, and has no `sort` or `fields`.

The endpoint ignores any query parameter it doesn't declare, and returns no error. A request that follows the standard rules gets the first page, unfiltered, every time.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `Api-Version` | header | string · v1 | yes | The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`. |
| `id` | path | string | yes | The unique identifier of the performance obligation whose products you want to retrieve. |
| `cursor` | query | string | no | The cursor from the previous response's data.pagination.nextCursor. Omit for the first page. |
