How to integrate Billingo in automation workflow?

3 simple steps to make your Billingo connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.

STEP 1

Select Billingo in workflow

Pick Billingo app in the workflow builder [4] - just one click to select the app.

STEP 2

Connect Billingo

When prompted, authorize access to Billingo in WEXTL once. Billingo credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].

WEXTL wants to integrate with your Billingo account. Approve?

STEP 3

Build a workflow

Build your workflow with Billingo yourself or with WEXTL® AI Builder. Connect Billingo to any available integrations [5], or use HTTP node to go beyond them.

Billingo

How Billingo connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Billingo app is called in workflows. That allows your finance automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Billingo supports.

Full Billingo API documentation

The following table illustrates what fields Billingo integration require during authorization flow inside our workflow builder [4].

Video slide demonstrates how Billingo is connected in WEXTL builder [4].

Field	Type	Help
Bilingo - API KeyRequired	password	You can generate a new API key on Billingo website.

Connect Billingo to popular apps on WEXTL

Enter a name of the other app you want to sync with Billingo below. Click on selected app to explore integration options with Billingo. 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 Billingo integration

Select Watch Document Blocks trigger from Billingo - this will be a starting point in your automation. Whenever event happens in Billingo, workflow will start [7] from Watch Document Blocks node.

Search for Create a Document, connect it as the next step of integration sequence. You can use filters between Watch Document Blocks and Create a Document, so only important data pass from Watch Document Blocks to the next step. WEXTL gives you full control over the process of Billingo automation. All parts of workflow are visible on the canvas [4].

Billingo on WEXTL has 118 modules for building finance automations. Explore Billingo documentation for more.

Frequently asked questions

Common questions about automating Billingo in your workflows.

Billingo has 12 triggers, including "Watch Bank Accounts", "Watch Bank Accounts", and "Watch Clients", and more. Triggers are start points of the workflow, and automations may start from them.

Integration has 106 actions, including "Get a Bank Account", "Get a Bank Account", and "Get a Client", and more. Refer to our Billingo 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 Billingo integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Billingo official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

Absolutely. Where Billingo 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 Billingo 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 Billingo 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 Billingo modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
