Sending extended content IDs to Index Exchange

Media Owners
Last Updated: April 30, 2026

You can now send an array of Content IDs (CIDs), where each ID is paired with the name of the data provider that issued it. A CID is a standardized identifier that describes video content using metadata from trusted third-party providers (such as content classification, ratings, or brand-safety vendors).

Sending CIDs helps programmatic platforms better understand your video content using identifiers they already recognize. This can improve content classification, targeting, measurement, and brand-safety decisions, ultimately increasing demand for your inventory.

To ensure a smooth transition and maintain backward compatibility:

Example

{
	"app": {
		"content": {
			"id": "ABC123-DEF456-GHI789",
			"data": [
				{
					"name": "dataprovider1.com",
					"cids": ["DP1001652800000"]
				},
				{
					"name": "dataprovider2.tv",
					"cids": ["DP2e3d0809045e003c"]
				}
			]
		}
	}
}
