Interchange documentation starts with what you are trying to accomplish. You do not need to choose an API, protocol, or account model before finding the right workflow.

Buy media

Create advertisers, discover products, launch campaigns, and understand delivery.

Sell media

Set up your Seller Account, connect inventory, respond to demand, and operate live media buys.

Use the Interchange interface

Find your way around the web application and its account-level controls.

Build an integration

Connect an agent or application through MCP or REST, then browse the API reference.

​
Documentation follows the job

Buyer and seller account types determine which actions and data you can access. They do not create separate products or separate documentation sites. The navigation groups account-specific workflows beneath the job they support, while shared concepts and platform behavior have one canonical explanation. If you are troubleshooting a live workflow, start from the relevant buying or selling section. If you are writing code or connecting an AI agent, switch to Build with Interchange.
