Common Issues

Connection issues

ChatGPT can't access my data flow

This usually happens when the authorization between ChatGPT and Coupler.io hasn't been completed or has expired. When you install the Coupler.io ChatGPT app, you'll be prompted to authenticate — make sure you complete that step and grant the requested permissions.

If you have already been authorized but still can't access data, try reinstalling the app.

Make sure your data flow has completed at least one successful manual run before trying to access it from ChatGPT. Data that hasn't been pushed yet won't be visible to ChatGPT.

The Coupler.io custom GPT doesn't appear or can't be opened

Custom GPTs require a ChatGPT Plus subscription or higher. If you're on the free plan, you won't be able to open or use custom GPTs. Upgrade your ChatGPT plan and try again.

Also, confirm you're using the correct link to the Coupler.io custom GPT — find it in your Coupler.io account under the ChatGPT destination settings.

Data issues

ChatGPT cannot identify column or field names (e.g., line item names from Shopify)

This can happen when column headers in your dataset are unclear, inconsistently named, or contain special characters. ChatGPT relies on column names to understand the structure of your data.

Try these fixes:

• Use the Data set step in the data flow wizard to rename columns to clear, descriptive names before sending data to ChatGPT.
• Avoid special characters, spaces, or abbreviations in column headers.
• Re-run your data flow after making changes so the updated schema is reflected.

If your source data uses generic field names (like "field_1" or "cf_123"), map them to human-readable names in the Coupler.io transformation step. This significantly improves ChatGPT's ability to interpret and answer questions accurately.

My data looks outdated in ChatGPT

ChatGPT only sees data that was sent during the last successful run of your data flow. If your data flow hasn't run recently, you'll be working with stale data.

Run your data flow manually to push the latest data, or set up a schedule so it refreshes automatically on a regular cadence.

When you start a new chat, ChatGPT automatically collects fresh data. If you want to get fresh data in the ongoing conversation, ask ChatGPT to fetch it.

Permission errors

Authorization prompt doesn't appear or keeps failing

If the Coupler.io authorization prompt doesn't appear when you open the ChatGPT app or custom GPT, try opening ChatGPT in a fresh browser tab or a private/incognito window. Browser extensions (especially ad blockers) can sometimes interfere with the OAuth pop-up.

Do not share your Coupler.io authorization credentials or tokens with others. Each user should authenticate with their own Coupler.io account.
