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

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

Connect OnceHub to popular apps on WEXTL
Enter a name of the other app you want to sync with OnceHub below. Click on selected app to explore integration options with OnceHub. 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 OnceHub integration
Select Watch Bookings trigger from OnceHub - this will be a starting point in your automation. Whenever event happens in OnceHub, workflow will start [7] from Watch Bookings node.
Search for Get a Booking Calendar, connect it as the next step of integration sequence. You can use filters between Watch Bookings and Get a Booking Calendar, so only important data pass from Watch Bookings to the next step. WEXTL gives you full control over the process of OnceHub automation. All parts of workflow are visible on the canvas [4].
OnceHub on WEXTL has 29 modules for combining scheduling automations. Explore OnceHub documentation for more.

Frequently asked questions
Common questions about automating OnceHub in your workflows.
OnceHub has 4 triggers, including "Watch Bookings", "Watch Contacts", and "Watch Events", and more. Triggers are start points of the workflow, and automations may start from them.
Integration has 25 actions, including "Get a Booking", "Get a Booking Calendar", and "Get a Contact", and more. Refer to our OnceHub 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 OnceHub integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by OnceHub official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where OnceHub 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 OnceHub 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 OnceHub 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 OnceHub modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
