How do I find my eSign App ID and Secret?

Log in to the [eSign Open Platform](https://open.esign.cn/), create a new application, and you will find your App ID and App Secret in the application credentials section.

Can I retrieve the signing URL for a participant?

Yes. Use the `get_execute_url` tool with the flow ID and the signer's account ID. Your agent will retrieve the unique URL where the participant can perform the signature.

Is it possible to download the signed documents?

Yes! Once a sign flow is completed, you can use the `download_docs` tool to retrieve temporary download links for all documents included in that flow.
