# Advanced Implementation Patterns

Use these guides when your HB Manager implementation needs custom auction logic, bidder settings, ad server targeting, or rendering behavior. Each guide covers a focused integration pattern.

### Auction data and targeting

* [Push Google slot information to the Prebid auction](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/afc67ff1bb4a004bfb8622ea1646af356f9ccb7e) — Pass Google Ad Manager slot data to the Prebid auction.
* [Retrieve Prebid and Amazon bid data](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/a5160b26b505c3e12ba8e201dabf5173b6fad23d) — Access bid data from Prebid and Amazon.
* [Add ad server targeting from bid response data](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/3d4592777b8bfd51302742c273ffbc5cf0483597) — Set ad server targeting from bid response values.

### Modify the Prebid auction

* [Remove sizes from the Prebid auction](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/0daf1c643e69c8031a47fd996ba69549b11c11bc) — Exclude selected sizes from an auction.
* [Edit bidder settings for schain and first-party data](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/15ffabb77b540c7069ce428c6445ca7e060a6aef) — Modify bidder settings for supply chain and first-party data.
* [Edit bidder parameters in `pbjs.adUnit`](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/c76db402317f6da06d0728ce165ae22a65bac068) — Update bidder parameters before an auction.
* [Add the GPID to `pbjs.adUnit`](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/f9910d476aeb1d0239d64a7623445d7b613e999f) — Add Global Placement IDs to Prebid ad units.

### Rendering and refresh behavior

* [Implementation and testing guidelines for direct rendering](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/4a4045dc9547bc8b70e24649ce9c1adbbe10ad03) — Implement and test direct rendering.
* [Set Google changeCorrelator in `pubads().refresh()`](broken://spaces/thyujPhgXh1WtJZy8bjr/pages/e3fef6cac9d3a7bf9ae3a58d8bab61a7417fefd6) — Set `changeCorrelator` during Google ad refreshes.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.relevant-digital.com/technical/integration/advanced-implementation-patterns.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
