My requirement is to fetch all the task links of a Project with Start - Id and End - Id of every task link.
Currently I'm only able to fetch LinkId, ProjUid, Lag and Dependency type using REST API -
https://contoso.sharepoint.com/sites/pwa/_api/ProjectServer/Projects('ProjectGUID')/TaskLinks
Then to Get Start - Id and End - Id, I have to again send two additional API requests and takes a lot of time when I have to fetch a total of 8000+ Task Links in a project with 8500 tasks.
