Yuki API Documentation

Modified on Tue, 11 Jun at 9:20 AM

Developer? To start the development of a new connection or update an existing one, we would like to redirect you to our API documentation regarding all technical information.

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

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, your accountant can activate an extra Webservice module in the Accountancy settings in your domain.

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.
