STEP 1
Select Function in workflow
Pick Function app in the workflow builder [4] - just one click to select the app.
Function Integration
Call a built-in or your own custom function as a single workflow step, with typed inputs and a result output. Add Function as a step in any automation on WEXTL. Combine it with app integrations and other built-in workflow nodes to move data, coordinate teams, or route logic across your stack.

How to integrate Function in automation workflow?
3 simple steps to make your Function connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.
STEP 2
Connect Function
When prompted, authorize access to Function in WEXTL once. Function credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].
Function Access Approval
WEXTL wants to integrate with your Function account. Approve?
STEP 3
Build a workflow
Build your workflow with Function yourself or with WEXTL® AI Builder. Connect Function to any available integrations [5], or use HTTP node to go beyond them.
Function
Connect Function to popular apps on WEXTL
Enter a name of the other app you want to sync with Function below. Click on selected app to explore integration options with Function. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.
Frequently asked questions
Common questions about automating Function in your workflows.
Function is a built-in WEXTL workflow node. In practice, call a built-in or your own custom function as a single workflow step, with typed inputs and a result output. Configure the node's settings panel to control how it behaves inside your automation.
Drop Function onto the visual canvas alongside app integrations and other built-in workflow nodes. Connect it to the steps before and after, configure its parameters, and it runs as part of the automation every time the workflow executes.
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. WEXTL authenticates every connection per account, encrypts credentials at rest, and lets you enforce approvals and team-level access controls on any automation that uses Function.
Function runs alongside app integrations on the same workflow canvas. It receives data from upstream steps (triggers or other nodes) and passes results to downstream steps. Refer to our Function Documentation for detailed inputs and outputs.
Absolutely. Function works with every trigger source and every app integration on WEXTL. Combine it with native app triggers, scheduled polling, or the Custom Webhook node so Function can react to events from any external system.
WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes like Function inside the workflow builder [4]. You can combine Function with app integrations and other built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) to build the exact flow you need.
