Ad and martech API deadlines 2027
AdStack Watch tracks 50 confirmed ad and martech API deadlines in 2027 across 7 platforms, each linked to the platform's own notice, starting January 1 with Shopify's expiring offline access token requirement for public apps calling the Admin API and TikTok's end of non-Search Legacy Manual Flow campaign creation. 3 more Google Ads dates are tentative and listed separately. The home page counts one upcoming confirmed date per change, while this page counts each confirmed 2027 date, so a change with an extra date or a headline date in another year is counted differently on each page. Rollouts and announcements without a deadline are not counted here or in the feeds.
50 confirmed · 3 tentative · last checked October 17, 2026 · next one in 76 days

Platforms covered here: Google Ads, Meta, LinkedIn Marketing API, TikTok Ads, Shopify, HubSpot, and Salesforce.

How we date things
A day-precision date is the day the platform published. A month-precision date is the month the platform published, shown as sometime in that month, not a chosen day. Google's sunset schedule says a month date could happen any time in that month, and the date could change. Salesforce dates that name a release season depend on when each org is upgraded. A date is tentative when the platform calls it tentative. Those rows sit in their own section and stay out of the headline count.
