How to integrate Yokoy in automation workflow?

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

STEP 1

Select Yokoy in workflow

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

STEP 2

Connect Yokoy

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

WEXTL wants to integrate with your Yokoy account. Approve?

STEP 3

Build a workflow

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

How Yokoy connects and integrates with WEXTL

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

Full Yokoy API documentation

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

Demonstration of Yokoy connection step inside WEXTL Workflow Builder [4].

Field	Type	Help
EnvironmentRequired	select	Select the environment to connect to. Use `Test` for development and testing purposes. Use `Production` for live data.
Client IDRequired	text	Enter your OAuth2 `Client ID`. To obtain this, log into your app as a developer user, navigate to Admin > Developer at the bottom of the Admin menu, and click Generate credentials. Select OAuth Credentials, enter a unique name, and your `Client ID` will be displayed. Copy it immediately as it is non-recoverable.
Client SecretRequired	password	Enter your OAuth2 `Client Secret`. This is generated alongside your `Client ID` in Admin > Developer. Copy it immediately as it is unique and non-recoverable. If lost, you must revoke access and generate new credentials.
Organization IDRequired	text	Enter your `Organization ID`. You can find this in the top right corner of Admin > Organization Settings if you have an organization admin role, or under Admin > Developer if you have a developer role.

Connect Yokoy to popular apps on WEXTL

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

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

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

Yokoy on WEXTL has 52 modules for building finance automations. Explore Yokoy documentation for more.

Frequently asked questions

Common questions about automating Yokoy in your workflows.

Yokoy has 4 triggers, including "Watch Expenses", "Watch Invoices", and "Watch Transactions", and more. Triggers are start points of the workflow, and automations may start from them.

Integration has 48 actions, including "Get a Purchase Order by ID", "Get a Supplier by ID", and "Get a Tag by ID", and more. Refer to our Yokoy 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 Yokoy integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Yokoy official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

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