Are CAPIs The Next Phase Of Performance TV? | AdExchanger

"Netflix entered the fray last week when it unveiled its conversion API, which is "designed to help advertisers prove outcomes," according to the company's blog post. But Netflix's CAPI is not just another glitzy product announcement ahead of the upfront season; it reflects the rising importance of the performance advertising mindset when it comes to streaming media."

"CAPIs are already a staple for digital ad channels, such as display, online video, search and social. Meta, Google, Snap and other platforms have CAPIs, which they use to more effectively inform buyers how their respective platform stands out within various media mixes. LinkedIn joined the CAPI club last year, too."

"In an ideal world, CAPIs could bridge the gap between advertisers' demands for proof of performance and the realistic possibilities of CTV attribution, which is historically a tricky feat. There are historically no tracking pixels on TV screens, and even with the advent of streaming, people just don't click around on TV devices the way they do on laptops or phones."

Conversion APIs (CAPIs) are becoming standard across streaming platforms as advertisers demand greater accountability for media spending. Netflix, Roku, and other streaming services have launched CAPIs to help buyers prove advertising outcomes and measure performance. These tools mirror similar offerings from digital platforms like Meta, Google, and LinkedIn. The shift reflects pressure on marketers to justify every dollar spent. Self-serve ad platforms from companies like Comcast are also emerging to attract smaller businesses and ecommerce brands. CAPIs aim to bridge the gap between advertiser demands for performance proof and the historical challenges of CTV attribution, though measuring TV advertising remains complex due to lack of tracking pixels and limited user interaction on TV devices.
