The Scenario
You are a developer at a marketing agency. Your agency built 18 Tally forms for client lead capture campaigns over the past six months. Every form needs to post submission data to the agency's CRM intake endpoint the moment a response comes in.
You have a Google Sheet with the form IDs in column A and the webhook callback URLs in column B. Some forms point to the same endpoint, some to client-specific ones.
The manual version:
- Log into Tally
- Open form one, navigate to the integrations tab, add the webhook, paste the URL, save
- Repeat for form two
- Realize on form seven that you pasted the wrong URL and have to go back
- Finish form 18 forty minutes later
- Discover that Tally changed its integrations UI layout last week and three of your webhooks are pointing to the wrong event type
- You block three hours for something that should have taken five minutes.
The fast version is one prompt.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent inside your spreadsheet that reads the form ID and URL pairs and handles the webhook registration calls for you.
Open the SheetXAI sidebar and type:
For each row in this sheet, create a Tally webhook using column A as the form ID and column B as the callback URL. Set the event type to "FORM_RESPONSE" for all rows. Write "DONE" into column C for each successful registration, and the error message into column C for any that fail.
SheetXAI iterates through all 18 rows, registers a webhook on each form via the Tally API, and writes the result back to column C. Successful registrations get "DONE," failures get the error text so you know exactly which ones to investigate.
What You Get
18 webhooks registered, one per row, with results written back to column C:
- Successful registrations — "DONE" in column C, webhook live and ready
- Failed registrations — error message in column C, so you know the exact failure reason
- Event type — "FORM_RESPONSE" set consistently across all 18 forms, no UI drift
- Audit trail — column C gives you a record of which webhooks registered cleanly
The error column is the important part. If form ID 12 returned a 404, that tells you the form was deleted or the ID is wrong. You fix the row and re-run just that one, without touching the other 17.
What If the Data Is Not Quite Ready
Webhook sheets built from multiple sources often have inconsistencies. SheetXAI handles them inline.
When some rows have event types in column C that differ from the default
Most forms should fire on new responses, but three should also fire on form close events.
For each row in this sheet, register a Tally webhook using column A as the form ID and column B as the callback URL. If column C contains an event type, use that. If column C is empty, default to "FORM_RESPONSE." Write the result back to column D.
When some form IDs in column A are duplicates
The sheet was assembled from multiple exports and a few form IDs appear more than once.
Before registering webhooks, deduplicate the rows in this sheet by form ID in column A. Keep the first occurrence of each form ID. Then register a webhook for each unique form ID using the URL in column B and write results to column C.
When the callback URLs use inconsistent protocols
Some rows in column B start with "http://" and others with "https://." Your CRM endpoint only accepts HTTPS.
Before registering webhooks, normalize all URLs in column B to start with "https://." Then register a Tally webhook for each row using column A as form ID and the normalized URL as callback. Set event type to "FORM_RESPONSE." Write results to column C.
When you need to register webhooks and immediately verify each one fired correctly
You want to confirm the webhooks are active after registration, not just trust the API response.
For each row in this sheet, register a Tally webhook using column A as the form ID and column B as the callback URL. After registering, fetch the webhook list for that form and confirm the registered URL appears. Write "VERIFIED" to column C if confirmed, "REGISTRATION FAILED" or "VERIFICATION FAILED" with the reason otherwise.
The pattern: the sheet is your operations log. You run the prompt, check column C, fix the failures, and re-run. No Tally dashboard needed.
