With Supabase Edge Functions

Create a new Supabase project and create a new Edge Function.

Prepare your database

Make sure to run the migrations, either by executing them manually, adding them into your CI, or running this locally once:

import { runMigrations } from '@supabase/stripe-sync-engine'
;(async () => {
  await runMigrations({
    databaseUrl: 'postgresql://postgres:..@db.<ref>.supabase.co:5432/postgre',
    schema: 'stripe',
    logger: console,
  })
})()

Usage

Sample code:

// Setup type definitions for built-in Supabase Runtime APIs
import 'jsr:@supabase/functions-js/edge-runtime.d.ts'
import { StripeSync } from 'npm:@supabase/stripe-sync-engine@0.37.2'

// Load secrets from environment variables
const stripeWebhookSecret = Deno.env.get('STRIPE_WEBHOOK_SECRET')!
const stripeSecretKey = Deno.env.get('STRIPE_SECRET_KEY')!

// Initialize StripeSync
const stripeSync = new StripeSync({
  poolConfig: {
    connectionString: Deno.env.get('DATABASE_URL')!,
    max: 20,
    keepAlive: true,
    // optional SSL configuration
    ssl: {
      ca: Buffer.from(Deno.env.get('DATABASE_SSL_CA')!).toString('utf-8'),
    },
  },
  stripeWebhookSecret,
  stripeSecretKey,
  backfillRelatedEntities: false,
  autoExpandLists: true,
  maxPostgresConnections: 5,
})

Deno.serve(async (req) => {
  // Extract raw body as Uint8Array (buffer)
  const rawBody = new Uint8Array(await req.arrayBuffer())

  const stripeSignature = req.headers.get('stripe-signature')

  await stripeSync.processWebhook(rawBody, stripeSignature)

  return new Response(null, {
    status: 202,
    headers: { 'Content-Type': 'application/json' },
  })
})

Deploy your Edge Function initially.

Set up a Stripe webhook with the newly deployed Supabase Edge Function URL.

Create a new .env file in the supabase directory.

DATABASE_URL="postgresql://postgres:..@db.<ref>.supabase.co:5432/postgres"
DATABASE_SSL_CA="<base64-encoded-ca>"
STRIPE_WEBHOOK_SECRET="whsec_"
STRIPE_SECRET_KEY="sk_test_..."

Load the secrets:

supabase secrets set --env-file ./supabase/.env

Note: Replace <base64-encoded-ca> with your actual base64-encoded certificate.

Generating Base64 from CA Certificate

To generate a base64-encoded CA certificate, follow these steps:

  1. Obtain the CA certificate file (e.g., prod-ca-2021.crt).

  2. Use the following command on Unix-based systems:

    base64 -i prod-ca-2021.crt -o CA.base64

  3. Open the CA.base64 file and copy its contents.

  4. Use the base64 string in your configuration or environment variables.
