Send form submissions to a webhook
Send responses to automation tools (like Make or Zapier), or any other Webhook endpoint you may have.
What is a webhook
A webhook is a way for one system (like Fillout) to send real-time data to another system (like the 3rd party tools you use) as soon as an event occurs. Under the hood, a webhook is an HTTP callback and can be a GET, PUT, POST or DELETE request.Connect your form to a webhook
1
Link your Fillout form to a webhook
Go to Integrate, and click 
Enter your Webhook URL, and 
Webhook.Test it. When you’re good with it, click Finish setup.2
Publish and share your form
Thats it! You have all you need to configure a webhook when the form submits.
Publish it and share the link.Available webhook options
Toggle theAdvanced view switch to set up your webhook with any of the parameters or arguments you need.
- These get added to the URL at the end.
- The left-hand side is the key, and the right-hand side is the value from your form or from anything else you can reference in Fillout.
- For example, if you add, on the left hand side, source, and then on the right hand side, pick reference of some short answer in your form, then your webhook will send:
- https://hooks.zapier.com/hooks/catch/12475312/abc/?source=answer to the short answer
- So if someone answered Facebook in the form, you will send: https://hooks.zapier.com/hooks/catch/12475312/abc/?source=facebook
- This is used if you’re sending a POST request. Most of the time, services like Zapier and Make will accept either GET or POST, and you can send information in the body of the message if you prefer instead.
- If using fields in the body of the message, make sure to process these correctly in Zapier/Make to make sure that they’re coming in the body and not the URL.
- Most users will not need to use this section. This is typically if you have an advanced webhook setup which requires sending extra headers
- The most typical use case for headers is if you have some verification required for your endpoint, and you have a special key you want to send, which will look something like:
- Authorization —> Bearer <secret_token>
- Similar to headers, most users will not need to send any here.
