For about the last year, we have had Zaps set up that use ChatGPT to automatically contact leads collected by Meta ads. Recently, all those Zaps started having errors and are no longer functional.

 

We’ve tried all the basic workarounds suggested: using the newer ChatGPT app, removing dynamic fields to test if that was the issue, trying different LLMs, trying shorter inputs/prompts, etc. but we can’t pinpoint the issue.

 

Does anyone have experience with this?

 

Some of the error messages we’ve received are:

  • The error "Failed to create a conversation in ChatGPT (OpenAI)" indicates that the request to the ChatGPT API could not be processed. This can happen for several reasons, including using an unsupported model, issues with the API key, or exceeding token limits.
  • The error indicates that the ChatGPT step in your Zap is unable to process the request due to an issue with the input data. Specifically, it seems that the model you are trying to use, "gpt-4o," is not receiving the expected values from the previous step, which may be causing the failure to create a conversation.

 

Thank you for your help!

Hi ​@Envida 

It may be a temp issue.

Make sure to check the OpenAI status page: https://status.openai.com/

I recommend subscribing to alerts about incidents.

For us to have more info, post screenshots showing:

  • how your Zap steps are outlined
  • how your Zap steps are configured in the CONFIGURE tab while in EDIT mode with the field mappings visible
  • the encountered error in the Zap Run

 

Make sure you are using:

  • updated Zap app versions
  • updated Zap app trigger/action versions
  • updated OpenAI models
  • check your billing info is update with OpenAI
  • check in OpenAI if you have exceeded token limits

I appreciate your response. I’ve attached some screenshots of how our zap is configured and the settings within the configurations section of the ChatGPT app.

 

The run error says exceeding current quota, but within OpenAI it shows we are nowhere near our billing or token quota.

 

Thank you for your help!

TIP: Try asking ChatGPT for help diagnosing the Zap step error by sharing a screenshot of your Zap Run step error with ChatGPT.

 

Check the returned error response URL: https://platform.openai.com/docs/guides/error-codes/api-errors

The error message in your Zap run is coming from the API step you used.
Here’s what it means:

📍 What the error means

Error: >429] You exceeded your current quota

  • The 429 status code means Too Many Requests, and in this case it specifically indicates you’ve run out of usage quota on your API account.

  • This is not a problem with itself — it’s coming from rejecting the request due to account limits.

⚡️ Why it happens

One or more of these is usually the cause:

  • You’re using the key (not the ChatGPT web app) and:

    • Your billing account has no active paid plan, or

    • Your prepaid credits are used up, or

    • You’ve hit the monthly quota limit set in your plan settings.

  • You might be on the free trial credits, and they have expired or been exhausted.

🛠️ How to fix it

  1. Check your usage and limits

  2. Check your billing settings

    • Go to: OpenAI Billing Settings

    • Make sure:

      • You have a valid payment method on file

      • You’ve set a usage limit high enough for your needs

  3. Increase or enable billing

    • If you have no paid plan, enable billing.

    • If you’ve hit your soft limit, raise it under “Usage limits.”

  4. Retry the Zap step once your quota is restored.

💡 Extra tip

  • The “ChatGPT ()” app uses your own API key from , so fixing quota/billing there will fix the error.

  • This error will keep appearing until quota is restored or a valid paid plan is active.
