Yuki API Documentation

What is an API?

An Application programming interface (API) is a collection of programming tasks (also known as interfaces) that will call the functions of a program. It makes it possible for programs to communicate and exchange information.

The API makes it possible for applications/services of external parties to exchange information with Yuki, for those domains where you have access to.



From the 1st of April 2019, Yuki will improve her SOAP-webservice security for your safety.

Our connections will only accept connections with security TLS 1.2 and higher. This shouldn't have any impact on most connection implementations (applications who are connected with Yuki to send data to Yuki or export data from Yuki).

Still any questions or doubts? Please contact your software partner, they should be able to help you. For further questions your software partner can send us an email at integrations@yuki.be


What can I do with the Yuki API?

  • Add Financial monitor graphs on your intranet web page
  • Export financial reports like Outstanding Items and the current balance
  • Create Sales invoices
  • Create General Journals
  • Import and export documents
  • Search in the archive
  • Import Petty Cash transactions


Technical Example

The technical information to build a connection can be found here. More detailed examples of the different API calls can be found on this page.

Financial monitor widgets

The financial monitor offers different types of graphs to monitor the financial data in Yuki. Yuki makes those data available as widgets. Therefore you can choose to display the graphs on your own intranet. [link naar pagina Financiele monitor widgets]. You can find more information about the widgets on this page.

Available webservices

At this moment we have seven webservices available. Each webservice contains one or more methods to exchange information:


Pay attention tot the GLaccounts and amounts when you deliver salesinvoices from a webshop (SalesInvoices).


Yuki costs webservices

As a standard, you can make up to 1000 webservice calls a day for each Yuki domain. If you will be in need of more calls, you can activate an extra Webservice module in the Yuki Store.

At this moment we offer our webservices based on a fair use policy. In case of unautorized use of our webservices we will be autorized to shut down the access to our API.
