We have a large data set of markers to upload to the cloud through the API, which is only one part of the process of the overall app. Our backend is operating on node.js and is processing batches of content asynchronously.
We have had issues in posting asynchronous http requests to Vuforia. The first target returns "targetCreated", but the subsequent requests return "targetAlreadyExist" - which is not the case.
We have then made the request to be synchronous and the problem has disapeared.
Does anyone know if there is a way to post asynchronous requests to Vuforia cloud or if we simply need to continue on a synchronous approach [which limits the upload to around 5000 targets per day]
