[Please help]What is a Gecko ID and confusion on GPO installation

[…]
“application”: {
“gecko”: {
“id”: “{id}” // Confused slightly with documentation and forums
}
},

  • In the gecko.id, should we use the registered email id (or) any random id(id generated by web-ext??).

  • During GPO installation, what ID should i use for installation is it any random id(If so, how can i get that ID)

  • In my usecase, I have to give multiple addons (each can have specific version wrt customer). In such scenarios, can i use gecko.id and push updates to AMO based on this id.
