How do I find my DingTalk App Key and Secret?

Log in to the DingTalk Developer Backend, create or select an 'Internal Enterprise Application', and you will find the App Key and App Secret under the 'Credentials' section.

Where can I find the Yida 'App Code'?

Open your Yida application, go to [Settings] → [Deployment and O&M], and you will find the 'App Code' (Application Code) there. It is required for all Yida API calls.

Can I see the approval history of a record?
