### Revenue Share at Taxonomy Level
Utilizing the API requires the data provider be set up as a data vendor in our system and that MediaMath act as a clearinghouse for all transactions. For third-party data providers, you'll work out terms with our partnerships team; for customers sharing first-party data, the revenue share will typically be set at 0 by our partnerships team.
Each data provider has a default revenue share, mutually agreed upon with the partnerships team; however, this default revenue share value can be overridden at a taxonomy level. For example, if a customer wants to target segments in MediaMath Platform at a rate which they have pre-negotiated with you, their data vendor, the customer's specific rate may require the use of a revenue share different from the default revenue share originally agreed upon between you & MediaMath. To facilitate this, you as the data provider, can create a permissioned taxonomy for the customer and work with the partnerships team to set a revenue share that relates to that specific taxonomy.
To override a revenue share at the taxonomy level, create the taxonomy with permissions and contact [MediaMath Support](https://mediamathsupport.force.com/s/) with the following information:
* the Taxonomy_ID,
* the desired taxonomy-level revenue share.

Our team will respond once they have updated the revenue share for the specified taxonomy.
