Third-party inventory properties (TPI)

| Addition | Net rates | New TPI rates | Available to pilot partners

In addition to Sell rates, the Demand API now supports Net rates for third-party inventory properties. These rates can be identified in search and availability responses by checking the inventory_type field.

  • It indicates the applied rate (e.g., "sell" or "net").

Example of accommodations/search response:

      "third_party_inventory": true,
      "inventory": {
        "third_party": true,
        "type": "net"
      }

Learn more in the Third-party inventory section.
