# DeleteKnowledgeBase
<a name="API_amazon-q-connect_DeleteKnowledgeBase"></a>

Deletes the knowledge base.

**Note**  
When you use this API to delete an external knowledge base such as Salesforce or ServiceNow, you must also delete the [Amazon AppIntegrations](https://docs.aws.amazon.com/appintegrations/latest/APIReference/Welcome.html) DataIntegration. This is because you can't reuse the DataIntegration after it's been associated with an external knowledge base. However, you can delete and recreate it. See [DeleteDataIntegration](https://docs.aws.amazon.com/appintegrations/latest/APIReference/API_DeleteDataIntegration.html) and [CreateDataIntegration](https://docs.aws.amazon.com/appintegrations/latest/APIReference/API_CreateDataIntegration.html) in the *Amazon AppIntegrations API Reference*.
