Do I need to change the API key when using the GCM 3.0 Instance API?

Question

I am currently integrating a new registration process GCM 3.0for push notifications using InstanceID API.

Before that, I use the method GCM 2.0 register()for push notifications, and for this I created a project on the Google developer console and created Server API keyto send push notifications to Device

So now that I go to GCM 3.0referring to the link. when creating the configuration file, it sets two things:

• Select an existing project or create a project
• Application Package Name

Providing these two details, it will automatically generate a new one Server API key, but I already created API keybefore that.

so is there a need to change the old API keyto the new API keyor stick to the old API key?

Answer 1

No, you can use the old API key.

Since the new process is just a new skin for creating an API key and sender ID.
