Issue with File Naming in Web API Document Upload

Question

Hello, 
 We've successfully implemented the web API document upload template in Appian, fetching documents and metadata from an external system. However, we've encountered an issue where the file name is consistently labeled as "Untitled Document" in the process. Any assistance in resolving this matter would be greatly appreciated. 
 Thanks

Hi shyam sudi , 
 When external system is calling our API, Add a header with name as "Appian-Document-Name" and value as the "filename.extension". 
 Then the document will be saved in Appian with filename.extension else it will give untitled document
