# Real-time Bidding API

## Overview

You can use the [Real-time Bidding
API](https://developers.google.com/authorized-buyers/apis/realtimebidding/reference/rest)
to manage your RTB integration with Google. Here are some things you can do with
the Real-time Bidding API:

- Manage [QPS quotas](https://developers.google.com/authorized-buyers/rtb/callout-quota-system)
- [Control what ad inventory you receive](https://developers.google.com/authorized-buyers/apis/guides/rtb-api/pretargeting-overview)
- [Submit creatives for review](https://developers.google.com/authorized-buyers/apis/guides/rtb-api/buyer-creatives#submit_creatives_for_review)
- [View creative status](https://developers.google.com/authorized-buyers/apis/guides/rtb-api/buyer-creatives#retrieve_existing_creatives)

## Resources

Many operations in the Real-time Bidding API are performed in the context of a
specific [bidder](https://developers.google.com/authorized-buyers/apis/guides/rtb-api/bidders) or
[buyer](https://developers.google.com/authorized-buyers/apis/guides/rtb-api/buyers), so most API resources
are directly under one of these two resources.

Bidders place bids for ad inventory on behalf of one or more buyers. In
Real-time Bidding, Bidders are represented by the
[`bidders`](https://developers.google.com/authorized-buyers/apis/realtimebidding/reference/rest/v1/bidders)
resource. You can use the `bidders` resource and its sub-resources to manage a
Real-time Bidding integration, or act on one or more resources for associated
buyers.

Buyers place ads and are billed for ad placements. In Real-time bidding,
buyers are represented by the
[`buyers`](https://developers.google.com/authorized-buyers/apis/realtimebidding/reference/rest/v1/buyers)
resource.

As a bidder, you can also act as a buyer if you bid on your own behalf. This is
represented in the API by `bidders` and `buyers` resources with the same
resource ID.

The bidders and buyers resources are read-only. If you need to modify values
for either resource, choose one of the following:

- Use the [Authorized Buyers UI](https://realtimebidding.google.com/)
