Hi there. I need help integrating a payment gateway called Peach Payments into my application. The first step is a cloud function to prepare the checkout. However, I am struggling to deploy the function to Firebase. Below is the code I am using for the cloud function. I urgently need help fixing it.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
// To avoid deployment errors, do not call admin.initializeApp() in your code
const axios = require('axios'); // Library for HTTP requests
exports.prepareCheckout = functions.region(region)
.runWith({
memory: '128MB'
})
.https.onCall((data, context) => {
if (!context.auth.uid) {
return; // User not authenticated, don't proceed
}
const amount = data.amount; // Extract amount from FlutterFlow request
const currency = data.currency; // Extract currency from FlutterFlow request
const paymentType = 'PA'; // Set paymentType to PA for pre-authorization
const url = 'https://eu-test.oppwa.com/v1/checkouts';
// Retrieve entityId and apiKey securely from Firebase environment variables
const entityId = process.env.PEACH_PAYMENTS_ENTITY_ID;
const apiKey = Buffer.from(process.env.PEACH_PAYMENTS_API_KEY, 'base64').toString('utf-8');
const headers = {
Authorization: Bearer ${apiKey},
};
const body = {
entityId,
amount,
currency,
paymentType,
};
return axios.post(url, body, { headers })
.then((response) => {
const checkoutId = response.data.id;
console.log('Checkout prepared successfully:', checkoutId);
return { checkoutId }; // Return checkout ID as JSON object
})
.catch((error) => {
console.error('Error preparing checkout:', error);
throw new functions.https.HttpsError('internal', 'Failed to prepare checkout');
});
});
