#### [ API ]

To update a knowledge base, send an [UpdateKnowledgeBase](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_agent_UpdateKnowledgeBase.html) request with a [Agents for Amazon Bedrock build-time endpoint](https://docs.aws.amazon.com/general/latest/gr/bedrock.html#bra-bt). Because all fields will be overwritten, include both fields that you want to update as well as fields that you want to keep the same.
