Zapier Adds Live API Access to OpenAI GPT-5.5

Zapier has made OpenAI’s GPT-5.5 available through its API-connected workflows, according to a LinkedIn post from CEO Wade Foster published on April 24, 2026. In the post, Foster said GPT-5.5 had taken the top position on Zapier’s leaderboard and confirmed that the API was now live in Zapier.

Key details

Zapier says OpenAI’s GPT-5.5 reached the top spot on its internal leaderboard.
The company announced that GPT-5.5 is now live for use in Zapier via the API.
The update suggests users can begin testing or deploying GPT-5.5 in automations and AI-powered workflows immediately.
The announcement was shared by Zapier CEO Wade Foster on LinkedIn.

For small business owners and builders, this means faster access to a newly released model inside existing automation workflows without waiting for separate integrations. It may also make it easier to compare model performance and update AI automations as new systems become available.

The talk emphasizes quality over quantity, with data showing 50% of SaaS SEO revenue comes from fewer than 10 high-performing pages.
