Maintain Knowledge Base via API

The authentication and invocation methods for the Knowledge Base API are consistent with the Application Service API. However, a single Knowledge Base API token generated has the authority to operate on all visible knowledge bases under the same account. Please pay attention to data security.

Advantages of Utilizing Knowledge Base API

Leveraging the API for knowledge base maintenance significantly enhances data processing efficiency. It enables seamless data synchronization via command-line interfaces, facilitating automated operations instead of manipulating the user interface.

Key advantages include:

• Automated Synchronization: Enables seamless integration between data systems and the Dify knowledge base, fostering efficient workflow construction.

• Comprehensive Management: Offers functionalities such as knowledge base listing, document enumeration, and detailed querying, facilitating the development of custom data management interfaces.

• Flexible Content Ingestion: Accommodates both plain text and file upload methodologies, supporting batch operations for addition and modification of content chunks.

• Enhanced Productivity: Minimizes manual data handling requirements, thereby optimizing the overall user experience on the Dify platform.

How to Use

Navigate to the knowledge base page, and you can switch to the API ACCESS page from the left navigation. On this page, you can view the dataset API documentation provided by Dify and manage the credentials for accessing the dataset API in API Keys.
