How to integrate Fillout in automation workflow?
3 simple steps to make your Fillout connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.
STEP 2
Connect Fillout
When prompted, authorize access to Fillout in WEXTL once. Fillout credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].
WEXTL wants to integrate with your Fillout account. Approve?
STEP 3
Build a workflow
Build your workflow with Fillout yourself or with WEXTL® AI Builder. Connect Fillout to any available integrations [5], or use HTTP node to go beyond them.

How Fillout connects and integrates with WEXTL
Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Fillout app is called in workflows. That allows your marketing automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Fillout supports.
The following table illustrates what fields Fillout integration require during authorization flow inside our workflow builder [4].

Connect Fillout to popular apps on WEXTL
Enter a name of the other app you want to sync with Fillout below. Click on selected app to explore integration options with Fillout. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.
Example automation with Fillout integration
Select Watch New Submissions trigger from Fillout - this will be a starting point in your automation. Whenever event happens in Fillout, workflow will start [7] from Watch New Submissions node.
Search for Create Form Submissions, connect it as the next step of integration sequence. You can use filters between Watch New Submissions and Create Form Submissions, so only important data pass from Watch New Submissions to the next step. WEXTL gives you full control over the process of Fillout automation. All parts of workflow are visible on the canvas [4].
Fillout on WEXTL has 9 modules for combining marketing automations. Explore Fillout documentation for more.

Frequently asked questions
Common questions about automating Fillout in your workflows.
Fillout has 2 triggers, including "Watch New Submissions" and "Watch New Submissions (Polling)". Triggers are start points of the workflow, and automations may start from them.
Integration has 7 actions, including "Get Form Metadata", "Get Form Submission", and "List Form Submissions", and more. Refer to our Fillout Documentation for detailed inputs and outputs.
No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].
Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.
The Fillout integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Fillout official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Fillout provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever Fillout or any other service sends event to webhook URL.
WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for Fillout inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with Fillout modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
