I need to know how I can get the scripts of my customers through some API (Web Dev Quasar Store)

Basically currently we use the tebex api which apparently will not be very useful, because when a script is transferred to a user it will not appear as a new owner, he is the owner of that asset in tebex and we are having problems because of this, if any dev or staff of fivem can help us find a solution, or if you can provide us an api by private it would be greatly appreciated to improve our support.
