Snapchat rolls out Snap Ads Between Stories, a new Ads API, and many ad improvements; all ads will be reviewed
Snapchat is ready to make the big bucks with a slew of important updates to its ads offering. They'll give advertisers the spotlight, buying flexibility, return on investment opportunities …
Context & Ripple Effects
This announcement lands six months after sources told Digiday that Snapchat was building an ad API and recruiting partners — today it ships, alongside Snap Ads Between Stories as a new placement and a blanket review policy for every ad. It marks the shift from hand-sold, direct-sales advertising to infrastructure third parties can buy against.
The arc continues afterward: buying gets easier with the self-serve Ad Manager and Certified Partners program a year later, formats expand into Promoted Stories and AR placements, and eventually the platform reaches beyond Snapchat's own app.
First-order effects
- Advertisers and their agency partners gain API-driven buying flexibility and a between-Stories placement, replacing one-off direct sales with programmatically purchasable inventory.
- Every ad now passes through review, raising the quality bar partners must clear before their creative runs.
Second-order effects
- An open API creates an ad-tech partner ecosystem around Snapchat's inventory — the foundation for the later Ad Manager launch and Certified Partners training program.
- More ad slots inside Stories put pressure on the viewing experience, which is exactly the tension Snapchat revisits when it later tests revenue-sharing mid-roll ads in US creators' Stories.
Third-order effects
- If the pattern holds, the ad platform outgrows the app itself: the same API plumbing underpins the Snap Audience Network extending ads into other apps, turning Snapchat from a media seller into a distribution layer.
- A reviewed, API-mediated ad marketplace becomes the prerequisite for sharing revenue with creators, restructuring who earns from Stories content.
The trend: Snapchat is converting a directly sold ad product into a programmatic platform that partners buy through, formats multiply within, and eventually other apps and creators monetize on.
