 You *must* only include one ID field - either `tagId` or `placement`, not both. If you have questions on which parameter to use, please reach out to your Account Manager.
 The `tagId` and `placement` are **mutually exclusive** but at least one is required. If you pass both, `tagId` takes precedence.
 
+Note: The Ybidder bidder adapter requires setup and approval from the Yieldbird team. Please reach out to [team@yieldbird.com](mailto:team@yieldbird.com) for more information.
