Overview
GPT Action Library: Zapier
A guide for connecting a custom GPT to Zapier via a GPT Action, importing Zapier's OpenAPI spec into ChatGPT to reach any of Zapier's 6,000+ supported apps. Use when an organization already has Zapier integrations and wants to expose them to ChatGPT without separate integration work. Not needed if the target app has its own dedicated GPT Action.
What it does
This is a guide for connecting a custom GPT in ChatGPT to Zapier via a GPT Action, giving the GPT instant access to Zapier's 6,000+ apps and 20,000+ actions. Most of the configuration happens on Zapier's side: the desired AI Actions are set up through Zapier's AI Action Manager, and Zapier's dynamically-generated OpenAPI spec is then imported into the GPT's Actions tab in ChatGPT's custom GPT creator, using "Import from URL".
When to use - and when NOT to
Use it when an organization already has Zapier integrations set up and wants to expose them to ChatGPT without separate integration work - for example a calendar-assistant GPT that looks up events and cross-references attendees' LinkedIn profiles, or a CRM GPT that lets a sales team update Hubspot contacts and notes from inside ChatGPT. It is not needed if the target app already has its own dedicated GPT Action, or if the organization doesn't use Zapier.
Inputs and outputs
Input is an AI Action configured in Zapier's AI Action Manager, plus Zapier's hosted OpenAPI URL (https://actions.zapier.com/gpt/api/v1/dynamic/openapi.json?tools=meta) imported into ChatGPT's Actions tab. Because most configuration happens on Zapier's side, the guide points readers to Zapier's own documentation on connecting GPTs to custom Zapier Actions before starting. Output is a working GPT Action that routes each request through Zapier to whichever app or action was configured on the Zapier side.
Integrations
Connects through Zapier as a hub, so any of Zapier's 6,000+ supported apps - calendars, CRMs like Hubspot, and more - become reachable from a single GPT Action without building a dedicated integration per app.
Who it's for
Developers and teams who already use Zapier and want to expose its existing integrations to a custom GPT instead of building per-app GPT Actions from scratch.

GPT Action Library: Zapier
Introduction
This page provides an instruction & guide for developers building a GPT Action for a specific application. Before you proceed, make sure to first familiarize yourself with the following information:
- Introduction to GPT Actions
- Introduction to GPT Actions Library
- Example of Building a GPT Action from Scratch
This GPT Action provides an overview of how to connect a GPT to Zapier. Because the majority of configuration occurs on Zapier, we recommend reviewing this helpful guide from Zapier on connecting GPTs to custom Zapier Actions.
Value + Example Business Use Cases
Value: Users can now connect custom GPTs within ChatGPT to Zapier and get instant integration to 6,0000+ apps and 20,000+ actions across the tech stack.
Example Use Cases:
- An organization has already setup Zapier integrations, and would like to avoid additional integration work when connecting their tech ecosystem with ChatGPT
- Build a Calendar Assistant GPT which looks up calendar events, and provides additional context based on attendees' LinkedIn profiles
- A CRM GPT to help connect Hubspot to ChatGPT allowing sales teams to update or review contacts and notes on the go
