How to integrate Stax Bill in automation workflow?

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

STEP 1

Select Stax Bill in workflow

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

STEP 2

Connect Stax Bill

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

WEXTL wants to integrate with your Stax Bill account. Approve?

STEP 3

Build a workflow

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

How Stax Bill connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Stax Bill 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 Stax Bill supports.

Full Stax Bill API documentation

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

Field Type Help

Field	Type	Help
Stax - API KeyRequired	text	Your Stax API secret key (`required`). - Once you log in to Stax Pay, you can create a key by clicking Apps from the side menu. On the Apps page, click API Keys, and then click Launch. On the API Keys App, click New Key. On the Key Creation page, enter a name for the key and assign a role, then click Save. The new key will appear in the list of keys. Click the key icon next to the API key to view, copy, or delete the key.

Example automation with Stax Bill integration

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

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

Stax Bill on WEXTL has 50 modules for building finance automations. Explore Stax Bill documentation for more.

Frequently asked questions

Common questions about automating Stax Bill in your workflows.

Stax Bill has 1 trigger, including "Watch Events". Triggers are start points of the workflow, and automations may start from them.

Integration has 49 actions, including "Get a Customer", "Get a File", and "Get a File by Tag", and more. Refer to our Stax Bill 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 Stax Bill integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Stax Bill official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

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