Important update: ChatGPT users – OpenAI Assistants API deprecation

OpenAI is deprecating the Assistants API. Zapier has deprecated all ChatGPT (OpenAI) steps that use it. On August 26, 2026, Zaps using these steps will stop working. If your Zaps use any of the affected steps, update them before that date.

What's changing

The following ChatGPT (OpenAI) steps are deprecated and hidden in the Zap editor:

  • Actions:
    • Conversation With Assistant (Legacy)
    • Create Assistant
    • Upload File (when used with assistants)
    • Create Vector Store
    • Create Vector Store File
  • Searches:
    • Find Assistant
    • Find or Create Assistant
  • Dropdowns used in the steps above:
    • List Assistants
    • List Vector Stores
    • List Assistant Files

These steps are no longer available when creating new Zaps. Existing Zaps that use them will continue to run until August 26, 2026, after which they'll stop working.

Find your affected Zaps

  1. Go to your Zaps.
  2. In the search or filter, select ChatGPT.
  3. Open each Zap and check if any step name matches the deprecated steps listed above.

What to do next

Replace deprecated steps with Responses API-based actions where possible, or redesign the workflow.

  • Use Conversation for back-and-forth conversations with memory, file search, web search, and MCP tool support.
  • Use Send Prompt for simple, one-off prompts that do not need memory.

After replacing the step, remap fields in later steps if needed, then test and publish your Zap.
