To set up your own FCM ID and Key follow the following steps:
1. Create New Project on Google Developers Console
Head to https://console.firebase.google.com/ and create a new project.
*2. Click the COG icon and select 'Project Settings'
3. Get credentials
Select "Cloud Messaging" in the navigation and then grab your "Sender ID" and "Legacy Server Key"
4. Add Credentials
Head back to your aimtell dashboard and then go to "View Websites" > "Edit" > "Advanced Settings". Once there, add your API key and Project ID into the corresponding fields. Hit save/update.
5. Update your manifest
Last but not least you'll need to update your aimtell-manifest.json file that you uploaded to the root directory of your website. If you haven't downloaded it yet (ie you just added your website) you can find this "View Websites" > "Edit" > "Installation".
Simply open the aimtell-manifest.json file and update the "gcm_sender_id" field with your Project ID and upload it back to your server.
Congratulations! You have now successfully added your own FCM keys.
