# ChatGPT API, stable product IDs and inline shopping placeholders

> Source: https://scrape.do/documentation/changelog/2026-06-23-chatgpt-shopping-placeholders/

2026-06-23 · feature

Every entry in `tool_data.shopping[]` now carries a stable **`id`**, and a new opt-in mode lets you render your own product cards inline without guessing positions.

## What's new

- **Stable product `id`.** Each `tool_data.shopping[]` entry now includes an `id` that is consistent for a given product within a response.
- **`shopping_placeholders=1`.** When set, each inline product in `output.markdown` is emitted as a `{{shopping:<id>}}` token instead of a link, where `<id>` matches a `tool_data.shopping[].id`.

## Why it matters

If you render product cards yourself, you can now scan `output.markdown` for `{{shopping:<id>}}` tokens and swap each for your own card, looked up by `id` in `tool_data.shopping[]`.

- **No positional drift.** The same product can appear at more than one inline position, and `tool_data.shopping[]` order does not always follow the text. Matching by `id` stays correct where counting positions would not.
- **Every token resolves.** A token is only emitted when its product has a matching `tool_data.shopping[]` entry; otherwise the product is left as normal text.
- **Backward compatible.** The mode is opt-in. Without it, responses are unchanged, and `output.html` and `data` are never affected by it.
