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

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

Connect Retell AI to popular apps on WEXTL
Enter a name of the other app you want to sync with Retell AI below. Click on selected app to explore integration options with Retell AI. 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 Retell AI integration
Select Watch Calls trigger from Retell AI - this will be a starting point in your automation. Whenever event happens in Retell AI, workflow will start [7] from Watch Calls node.
Search for Create a Phone Call, connect it as the next step of integration sequence. You can use filters between Watch Calls and Create a Phone Call, so only important data pass from Watch Calls to the next step. WEXTL gives you full control over the process of Retell AI automation. All parts of workflow are visible on the canvas [4].
Retell AI on WEXTL has 6 modules for combining communication automations. Explore Retell AI documentation for more.
Video slide demonstrates how Watch Calls and Create a Phone Call [6] nodes are used in Retell AI workflow.
Frequently asked questions
Common questions about automating Retell AI in your workflows.
Retell AI has 1 trigger, including "Watch Calls". Triggers are start points of the workflow, and automations may start from them.
Integration has 5 actions, including "Get a Call", "Search Calls", and "Create a Phone Call", and more. Refer to our Retell AI 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 Retell AI integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Retell AI official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Retell AI 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 Retell AI 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 Retell AI 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 Retell AI modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
