Firebase mobile payments: Cloud Functions for Firebase

Deploy and test

• Create a Firebase Project using the Firebase Developer Console
• Enable billing on your project by switching to the Blaze or Flame plan. See pricing for more details. This is required to be able to do requests to non-Google services.
• Enable Google & Email sign-in in your authentication provider settings.
• Install Firebase CLI Tools if you have not already and log in with firebase login.
• Configure this sample to use your project using firebase use --add and select your project.
• Install dependencies locally by running: npm install
• Add your Stripe API Secret Key to Firebase config:

  firebase functions:config:set stripe.secret=<YOUR STRIPE SECRET KEY>

• Deploy your project using npm run deploy

Setting up webhooks

• Run firebase open functions to open the Firebase console.
• Copy the URL for the handleWebhookEvents functions (e.g. https://region-project-name.cloudfunctions.net/handleWebhookEvents)
• Create a new webhook endpoint with the URL in the Stripe Dashboard
• Copy the signing secret (whsec_xxx) and add it to Firebase config:

  firebase functions:config:set stripe.webhooksecret=<YOUR WEBHOOK SECRET>

• Redeploy the handleWebhookEvents function: firebase deploy --only functions:handleWebhookEvents

Accepting live payments

Once you’re ready to go live, you will need to exchange your test keys for your live keys. See the Stripe docs for further details.

• Update your Stripe secret config:

  firebase functions:config:set stripe.secret=<YOUR STRIPE LIVE SECRET KEY>

• Set your live publishable key in your respective client integration.
• Follow the Setting up webhooks from above for live mode.
• Redeploy the functions for the changes to take effect npm run deploy.
