Hi @SIVARANJANI VASUDEVAN

You first need to plan for authentication. you can use oauth or login into devops and generate a PAT token: https://docs.searchunify.com/Content/Content-Sources/Azure-Generate-Personal-Access-Token.htm

This is how you use in Postman: https://www.sanderh.dev/call-Azure-DevOps-REST-API-Postman/

to upload to a work item you need two operations/apis

First the one on the link you posted:

POST https://dev.azure.com/fabrikam/_apis/wit/attachments?fileName=imageAsFileAttachment.png&api-version=5.1

that will upload the attachment to devops and return a url. with that url you can finally attach to the work item using this second api: https://dev.azure.com/fabrikam/_apis/wit/workitems/2?api-version=5.0
