Offering a Yuki API integration allows you to:
- Setup automated processes for your users such as automated accounting entries
- Pull accounting data into your software for synchronisation or offer features such as forecasting
- Enhance overall accuracy by reducing the risk of error associated with manual entries
In this article you’ll discover how to make the most of the Yuki API with expert tips, clear explanations, and common use cases.
What is the Yuki API?
The Yuki API allows you to access and perform operations on a wide range of accounting resources within your product, such as:
- Invoices
- Journal entries
- Chart of accounts
- Customer and supplier data
Yuki’s API is based on SOAP (Simple Object Access Protocol), which means it requires strict adherence to the defined schemas and namespaces for requests to be properly interpreted.
Through Chift’s Unified Accounting API, software vendors can effortlessly connect to Yuki and many more accounting software, simplifying their integration strategy.

Getting you started with your Yuki API integration
There are two primary levels of authentication and setup when integrating with Yuki:
- Client-Level Access (for vendors): You’ll need a Client ID and Client Secret to allow customers to interact with Yuki through your application.
- Customer-Level Access: Each end-user must provide their Yuki API key, which is only available to customers on the Business Plan. This key allows access to their Yuki environment via the API.

Our recommendations for integrating with Yuki
Here are some tips to help you experience a smoother integration setup with Yuki’s API
- Batch your requests: Yuki enforces a daily limit of 1,000 API requests per day, so avoid small and frequent API calls. Instead, group operations into fewer, larger batches.
- Respect SOAP schema and namespaces: Since Yuki uses a SOAP API, you must pay close attention to the request structure. Mistakes in namespaces or schema will cause your request to be rejected.
