How to integrate Klara in automation workflow?

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

STEP 1

Select Klara in workflow

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

STEP 2

Connect Klara

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

WEXTL wants to integrate with your Klara account. Approve?

STEP 3

Build a workflow

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

Klara

How Klara connects and integrates with WEXTL

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

Full Klara API documentation

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

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

Field	Type	Help
KLARA - API KeyRequired	password	Navigate to the `User` menu item, Click on the option to add a new API key, Enter a name for the API key Assign the API key to at least one user role in KLARA and copy the generated key

Connect Klara to popular apps on WEXTL

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

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

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

Klara on WEXTL has 74 modules for combining communication automations. Explore Klara documentation for more.

Frequently asked questions

Common questions about automating Klara in your workflows.

Klara has 5 triggers, including "Watch New Articles", "Watch New Customers", and "Watch New Customers Address", and more. Triggers are start points of the workflow, and automations may start from them.

Integration has 69 actions, including "Get a Customer", "Get a Customer Address", and "Get a Letter", and more. Refer to our Klara 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 Klara integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Klara official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

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