​ To learn more, see the sources I considered: [[1] RetellAI/retell-python-sdk/api.md](https://github.com/RetellAI/retell-python-sdk/blob/main/api.md) ​

### Answer Based on the Python SDK documentation, there is no method to delete multiple knowledge base sources in a single API call. [(1) ]() The available methods for knowledge base source management are: -

client.knowledge_base.add_sources(knowledge_base_id, **params)

— adds sources (supports multiple) -

client.knowledge_base.delete_source(source_id, *, knowledge_base_id)

— deletes a single source To delete multiple sources, you would need to call

delete_source

individually for each source you want to remove.

### Answer I don't have information about the specific error code returned when uploading a file larger than 100MB via the Retell AI API. The available sources cover phone number management and API integration concepts, but don't document file upload size limits or their corresponding error responses. Check out these potentially useful sources: - [Import Phone Number]() - [Delete Phone Number]() - [API Integration]() For specific details about file upload limits and error codes, you may want to check the knowledge base API documentation directly or reach out via [Contact Sales]() or the [Retell AI GitHub]() . Would you like me to try providing a general answer based on common API patterns instead?
