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

How Wave connects and integrates with WEXTL
Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Wave 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 Wave supports.
The following table illustrates what fields Wave integration require during authorization flow inside our workflow builder [4].

Connect Wave to popular apps on WEXTL
Enter a name of the other app you want to sync with Wave below. Click on selected app to explore integration options with Wave. 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 Wave integration
Select Watch Customer Invoices trigger from Wave - this will be a starting point in your automation. Whenever event happens in Wave, workflow will start [7] from Watch Customer Invoices node.
Search for Create a Customer, connect it as the next step of integration sequence. You can use filters between Watch Customer Invoices and Create a Customer, so only important data pass from Watch Customer Invoices to the next step. WEXTL gives you full control over the process of Wave automation. All parts of workflow are visible on the canvas [4].
Wave on WEXTL has 22 modules for building finance automations. Explore Wave documentation for more.
Video slide demonstrates how Watch Customer Invoices and Create a Customer [6] nodes are used in Wave workflow.
Frequently asked questions
Common questions about automating Wave in your workflows.
Wave has 5 triggers, including "Watch Businesses", "Watch Customer Invoices", and "Watch Customers", and more. Triggers are start points of the workflow, and automations may start from them.
Integration has 17 actions, including "Get a Customer", "Get User", and "List Accounts", and more. Refer to our Wave 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 Wave integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Wave official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Wave 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 Wave 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 Wave 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 Wave modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
