What is this?

The Tally integration messages people on WhatsApp right after they submit one of your Tally forms. Each connection watches one form.

What can I do here?

  • Send a WhatsApp template when a form is submitted
  • Connect several forms, each with its own message
  • See every submission Tally sent, including failures
  • Have every submission checked with a signature the platform generates

How to use it

1

Open the Tally page

Go to Integrations, click Tally, then Connect.
2

Enter your Tally details

  1. Paste your Tally API key (in Tally under Settings → API keys).
  2. Enter the Tally form ID or link, for example https://tally.so/r/AbC123.
3

Choose your messages

Pick the WhatsApp template to send when the form is submitted:Leave an event empty to send nothing for it.
4

Set up and activate

Click Set up and activate. The platform registers the webhook with Tally for you and creates a ready-made automation that sends the right template for each event. You can open that automation in the builder any time.

Things to know

  • The customer’s phone number is taken from a phone-number input field, or from the answer to a question labelled like a phone number. Make sure your form asks for one — submissions without a phone number can’t be messaged.
  • Repeats are ignored. If Tally sends the same event twice, the customer isn’t messaged twice.
  • One connection per form. To watch another form, connect Tally again with that form’s ID.

Troubleshooting / Technical Notes

  • Connecting fails. Check the details you entered and that they belong to the right Tally account. The error from Tally is shown on the page.
  • No messages are sent. Check the connection shows Connected, a template is chosen for the event, and the template is approved.
  • A request shows as failed. Open the connection’s Activity tab and select the request to see the error and its raw body. A missing phone number is the most common cause.
  • Webhooks look missing. On the connection page, click Verify on Tally to check they are still registered. If any are missing, disconnect and reconnect to register them again.
  • You rotated your key or token. Open the connection’s Settings tab and update the credentials.
