How to: Setup Push Notifications with OneSignal

1. Go to onesignal.com. From the OneSignal site, click on Login in the top right-hand corner
   
   
   
   If you are a returning user, use your existing credentials to login to your OneSignal account. You can create multiple app entries under the same account.
   
   
2. If you need to create a new account click the Sign Up button down the bottom of the pop-up window
   
   
   
3. Fill in your details and Confirm your account
   
   
4. Once your account has been confirmed you can login to your OneSignal account and begin setting up push notification for iOS and Android.

To enable iOS push notifications, you must export your iOS push notifications certificate as a production .P12 file, then upload this file to OneSignal.

Exporting your Push Notifications Certificate as a .P12

1. After creating your push notifications certificate and adding it to your Mac computer's Keychain, open the Keychain Access application.
   
   
2. Select the login keychain, and the Certificates category. Identify your push notification certificate.
   The certificate should be identifiable by its name, and the date on which it expires (one year after creation).
   
   
   
3.  Hold the control key and click on your push notifications certificate. In the menu that appears, choose to Export your certificate.
   
   
   
4. Save the exported certificate as a .P12 file type. This is extremely important, as parse.com will only read .P12 files. As per usual practice, save the .P12 file with an easily identifiable name, in a memorable location.
   
   
5. Next, two dialogue boxes will appear. In the first box, you will be asked to create a password to protect your .P12 file – do not enter a password here.
   
   Leave both fields blank and click the OK button. Again, this is extremely important as parse.com will not be able to access your certificate if you enable password protection.
   
    
6. The second dialogue box will ask for your computer's system user password. Go ahead and enter your password here, then click Allow to finish exporting your certificate as a .P12.
   
   
   You now have a modified .P12 certificate.
   
   Next, you will upload this file to OneSignal.

1. Go to OneSignal website
   
   
2. Click Login. If you have a OneSignal account you should login - if not register an account.
   
   
   
   
3. Once logged in - you will be able to Add a New App
   
   
   
   
4. Name your app appropriately and click Create
   
   
   
   
5. Select the Apple iOS platform and click Next
   
   
   
   
6. You will be brought to a new screen with the option to upload a Sandbox .p12 or a Production .p12. Upload a Production .p12 file. You may ignore the Sandbox .p12 option.
   
   
    
   
   If you haven't created a .p12, see the previous step on Creating a Production .p12. 
   
   
7. Click Save and click Continue on the next screen
   
   
   
   
8. The following steps will be regarding Apple SDK which you may ignore - you can simply click the cross and exit the process.
   
   
   
   
9. Your iOS OneSignal configuration is complete. You may refresh your browser to see the changes applied to your Apple Configuration.
   
   
   
   
10. The next step is to configure your app in Ubiquity (Liquid State Cloud) so you can send Push Notifications. You should keep this tab open in your browser as you'll need in the next step.

1. Login to your Liquid State account
   
   
2. Click on the app you're going to configure

5. Select the box Send Push Notifications using OneSignal
   
   
   
   
6. Open OneSignal.com in your browser and log back in
   
   
7. Click on the app entry that you're planning to configure
   
   
   
8. Click on App Settings along the left-hand tab
   
   
   
   
9. Click on Keys & IDs after clicking App Settings to access your automatically generated OneSignal App ID and REST API Key
   
   
   
   
10. Copy the OneSignal App ID and paste into the matching section on Ubiquity/Cloud
    
    
    
    
    
    
11. Copy the REST API Key from OneSignal to Ubiquity/Cloud
    
    
    
    
    
    
12. Your configuration is complete for iOS Push Notifications. Hit Save & Continue to finish.
