I want to create custom products for every single one of my customers, and to add a thumbnail and custom order data from a JSAPP.
Seen on #2 My JS application must get the unique id from the user. regardless if they are logged in or not (i dont know how which is the exact data or variable in the db i should send, and how do i send it?)
in #3 i must recieve custom information generated on the jsapp, i can send this as a Json , XML or URLstring from the jsapp to drupal commerce; im unsure how could i somehow, inject this information or update a variation of my product. or maybe there's a more easy way to do this.
Does anyone have some pointers on how to address this communication problem?
