Everything in KLARA.
Open to more.
Connect KLARA Business to online shops, industry-specific solutions, and your own applications. With the KLARA API, you can automate data exchange, avoid duplicate entries, and keep your data up to date.
97 endpoints for integrations.
Do less manual work.
Automate more.
Many companies enter the same information into multiple systems: in their online shop, in an industry-specific solution, in their CRM, and again in their accounting system. The KLARA API connects these systems to KLARA and enables automated, end-to-end processes.

Use Cases
Each use case links directly to the corresponding section of the documentation.
Create Invoices
Create shop in KLARA directly from your online shop, CRM, or industry-specific solution. Customer data and invoice information are automatically transferred.
Send invoices
You don't have to decide how the invoice will be delivered to the customer. KLARA automatically selects the appropriate delivery channel—ePost, eBill, email, or post. If you prefer, you can specify the channel yourself.

Reuse financial and VAT data
Automatically retrieve relevant financial and VAT data for analysis, reporting, or collaboration with your accountant.
Additional Use Cases

Integrate in four steps
Select a process
Decide which system you want to connect to KLARA and which manual task you want to automate.
Create an API key
In KLARA, create an API key under "Users" and assign it to the appropriate role. Assign only the roles that your use case actually requires.
Connect to the API
Your development team or integration partner implements the integration using the technical documentation and tests the required API calls carefully.
Automate the process
Once testing is complete, data exchange occurs automatically and can be monitored on an ongoing basis.
