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

How Billdu connects and integrates with WEXTL
Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Billdu 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 Billdu supports.
The following table illustrates what fields Billdu integration require during authorization flow inside our workflow builder [4].
Video slide demonstrates how Billdu is connected in WEXTL builder [4].
| Field | Type | Help |
|---|---|---|
API KeyRequired | text | Your API key. Found under Settings > API in your account. |
API SecretRequired | password | Your API secret used to sign every request. |
Connect Billdu to popular apps on WEXTL
Enter a name of the other app you want to sync with Billdu below. Click on selected app to explore integration options with Billdu. 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 Billdu integration
Select Watch Documents trigger from Billdu - this will be a starting point in your automation. Whenever event happens in Billdu, workflow will start [7] from Watch Documents node.
Search for Delete a Document, connect it as the next step of integration sequence. You can use filters between Watch Documents and Delete a Document, so only important data pass from Watch Documents to the next step. WEXTL gives you full control over the process of Billdu automation. All parts of workflow are visible on the canvas [4].
Billdu on WEXTL has 21 modules for building finance automations. Explore Billdu documentation for more.
Video slide demonstrates how Watch Documents and Delete a Document [6] nodes are used in Billdu workflow.
Frequently asked questions
Common questions about automating Billdu in your workflows.
Billdu has 3 triggers, including "Watch Clients", "Watch Documents", and "Watch Products". Triggers are start points of the workflow, and automations may start from them.
Integration has 18 actions, including "Get a Client", "Get a Document", and "Get a Product", and more. Refer to our Billdu 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 Billdu integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Billdu official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Billdu 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 Billdu 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 Billdu 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 Billdu modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
