What can I build with the Tally API?
You can programmatically create and manage forms, update fields dynamically, fetch and delete submissions, and sync data with external tools like Notion, Airtable, Google Sheets, or your own database. Developers have used it to build AI agents, automated onboarding flows, client intake systems, and custom form backends.
Can I use the Tally API with Make, n8n, or Zapier?
Yes. The Tally API works great alongside no-code automation tools. Use it to create or update forms dynamically, then route submission data through your automation stack. Many users combine the API with Make or n8n to build end-to-end workflows.
How do I authenticate with the Tally API?
The Tally API uses token-based authentication. Find your API key in your account settings and include it as a Bearer token in your request headers. Full details in the developer docs.
Does Tally have webhooks or just an API?
Tally has both. Webhooks push data to your tools automatically when a form is submitted. The API gives you full programmatic control — create forms, manage submissions, update fields, and more. Many users use both together.
Can I create forms programmatically and prefill fields?
Yes, you can create forms via the API and dynamically set field values, making it easy to personalise forms per user, event, or client without manual setup.
