Stripe

The stripe webhook allows you to get real-time updates about various stripe events.

Verification

Stripe validates the authenticity of its webhook events by including a signature in each event's header.

Rowy automatically handles the complexity of the signature verification process, you just need to have a secret key named stripe in the Google Secret Manager created.

Parser

The sample parser provided increments profile credits when the Stripe checkout.session.completed event is triggered.

const stripeParser: Parser = async ({ req, db, ref, logging }) => {
  const { FieldValue } = await import('@google-cloud/firestore');

  try {
    const event = req.body;
    // For event types: https://stripe.com/docs/api/events/types
    switch (event.type) {
      case "checkout.session.completed":
        logging.log("Checkout completed");

        // Get the user id from the metadata
        // For more info: https://stripe.com/docs/api/metadata
        const { uid } = req.body.data.object.metadata; 

        const profile = await db
          .collection("profiles")
          .where("userId", "==", uid)
          .get();

        if (!profile.empty) {
          const profileData = profile.docs[0];
          await db
            .collection("profiles")
            .doc(profileData.id)
            .update({ 'package.limit': FieldValue.increment(100) });
        }

        break;
      case "payment_intent.payment_failed":
        // Handle failed payment here
        logging.error("Payment failed");
        break;
    }
  } catch (error) {
    logging.error(error);
  }
};
