Deal synchronization options

Marketplace Partners
Last Updated: February 12, 2026•

For a deal to become active, the deal must be set up by Index Exchange and then be registered in the buyer's DSP. This process can occur in the following ways:

Non-programmatic (manual) deal synchronization

In this method, deal synchronization is a non-programmatic communication between Index and buyers.

Programmatic (automatic) deal synchronization

In this method, deal synchronization occurs using an API and deals are programmatically synchronized between Index and buyers.

The key benefits of using a programmatic synchronization process are:

  • Seamless deal setup process between Index and buyers.

  • Elimination of requirement for buyers to manually set up their deals in their DSP's UI.

  • Quicker and less error-prone.

DSPs that support programmatic deal synchronization with Index

The following table lists the DSPs that offer programmatic deal synchronization with Index and provides details on how the process works. Any DSPs not listed below use a non-programmatic method.

DSPHow it works
