The Resend Webhook Ingester is an open-source Next.js application that receives, verifies, and stores all your webhook events in your own database. Deploy it to your infrastructure and gain full control over your email event data. :::callout{intent="info"} For more details on why you should store your webhook data, see the [data storage guide](/guides/learn-webhooks-how-to-store-webhooks-data). ::: ## Why use the Webhook Ingester While you can build your own webhook handler, the Webhook Ingester provides a production-ready solution with: - **Signature verification** using Svix to ensure webhook authenticity - **Idempotent storage** that safely handles duplicate webhook deliveries - **Multiple database support** including PostgreSQL, MySQL, MongoDB, and data warehouses - **One-click deployment** to Vercel, Railway, or Render ::::card-grid :::card{title="GitHub Repository" href="https://github.com/resend/resend-webhooks-ingester" icon="github"} View the source code and contribute ::: :::card{title="Docker Image" href="https://ghcr.io/resend/resend-webhooks-ingester" icon="docker"} Pull the official Docker image ::: :::: ## Deploy Get started in minutes with one-click deployment: [Deploy with Vercel](https://vercel.com/new/clone?repository-url=https://github.com/resend/resend-webhooks-ingester\&env=RESEND_WEBHOOK_SECRET\&envDescription=Your%20Resend%20webhook%20signing%20secret\&envLink=https://resend.com/webhooks) [Deploy on Railway](https://railway.com/deploy/cd2lvJ?referralCode=w2CHHM\&utm_medium=integration\&utm_source=template\&utm_campaign=generic) [Deploy to Render](https://render.com/deploy?repo=https://github.com/resend/resend-webhooks-ingester) Or use Docker: ```bash theme={"theme":{"light":"github-light","dark":"vesper"}} docker pull ghcr.io/resend/resend-webhooks-ingester ``` ## Supported Databases | Database | Endpoint | Best For | | ----------- | -------------- | -------------------------------------- | | Supabase | `/supabase` | Quick setup with managed Postgres | | Neon | `/neon` | Serverless Postgres with branching | | PostgreSQL | `/postgresql` | Self-hosted or managed Postgres | | MySQL | `/mysql` | Self-hosted or managed MySQL | | PlanetScale | `/planetscale` | Serverless MySQL | | MongoDB | `/mongodb` | Document database (Atlas, self-hosted) | | Snowflake | `/snowflake` | Data warehousing and analytics | | BigQuery | `/bigquery` | Google Cloud analytics | | ClickHouse | `/clickhouse` | High-performance analytics | ## Quick Start :::::steps :::step{title="Clone and install"} ```bash theme={"theme":{"light":"github-light","dark":"vesper"}} git clone https://github.com/resend/resend-webhooks-ingester.git cd resend-webhooks-ingester pnpm install ``` ::: ::::step{title="Configure environment variables"} Copy the example environment file and add your credentials: ```bash theme={"theme":{"light":"github-light","dark":"vesper"}} cp .env.example .env.local ``` At minimum, you need: ```env .env.local theme={"theme":{"light":"github-light","dark":"vesper"}} # Required: Your Resend webhook signing secret RESEND_WEBHOOK_SECRET=whsec_xxxxxxxxxxxxxxxxxxxxx # Database credentials (example for PostgreSQL) POSTGRESQL_URL=postgresql://user:password@host:5432/database ``` :::callout{intent="info"} Get your webhook signing secret from the [Resend Dashboard](https://resend.com/webhooks) when creating a webhook. ::: :::: :::step{title="Set up your database"} Set up your database and run the provided schema for your database. The ingester supports PostgreSQL, MySQL, MongoDB, and several data warehouses. Schema files can be found in the `schemas/` directory. ```bash theme={"theme":{"light":"github-light","dark":"vesper"}} pnpm db:setup --postgresql # or use a different flag for a different database ``` ::: :::step{title="Deploy and register webhook"} Deploy to your preferred platform, then register your webhook endpoint in the [Resend Dashboard](https://resend.com/webhooks) and select all the events you'd like to store. Your endpoint URL will be: `https://example.com/{connector}` For example: `https://your-app.vercel.app/postgresql` ::: ::::: ## Database Schemas The ingester creates three tables to store webhook events: | Table | Description | | -------------------- | ------------------------------------------------------------ | | `resend_wh_emails` | All email events (sent, delivered, bounced, opened, clicked) | | `resend_wh_contacts` | Contact events (created, updated, deleted) | | `resend_wh_domains` | Domain events (created, updated, deleted) | Each table includes: - `svix_id` - Unique webhook event ID for idempotency - `event_type` - The type of event (e.g., `email.delivered`) - `event_created_at` - When the event occurred - `webhook_received_at` - When the webhook was received - Event-specific fields (e.g., email details, bounce info, click data) ## Idempotency The ingester handles duplicate webhooks automatically. Each webhook includes a unique `svix-id` header, and the ingester uses this to ensure events are stored only once. If Resend retries a webhook delivery (due to a temporary failure), the duplicate will be safely ignored without creating duplicate records in your database. ## Configuration Reference ### Required Environment Variables | Variable | Description | | ----------------------- | --------------------------------------- | | `RESEND_WEBHOOK_SECRET` | Your webhook signing secret from Resend | ### Database-Specific Variables ::::accordion-group :::accordion{title="Supabase"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} SUPABASE_URL=https://your-project.supabase.co SUPABASE_SERVICE_ROLE_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9... ``` ::: :::accordion{title="Neon"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} NEON_DATABASE_URL=postgresql://user:password@ep-xyz.us-east-1.aws.neon.tech/database?sslmode=require ``` ::: :::accordion{title="PostgreSQL"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} POSTGRESQL_URL=postgresql://user:password@host:5432/database ``` ::: :::accordion{title="MySQL"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} MYSQL_URL=mysql://user:password@host:3306/database ``` ::: :::accordion{title="PlanetScale"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} PLANETSCALE_URL=mysql://username:password@host/database?ssl={"rejectUnauthorized":true} ``` ::: :::accordion{title="MongoDB"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} MONGODB_URI=mongodb+srv://username:password@cluster.mongodb.net/ MONGODB_DATABASE=resend_webhooks ``` ::: :::accordion{title="Snowflake"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} SNOWFLAKE_ACCOUNT=your-account-identifier SNOWFLAKE_USERNAME=your-username SNOWFLAKE_PASSWORD=your-password SNOWFLAKE_DATABASE=your-database SNOWFLAKE_SCHEMA=your-schema SNOWFLAKE_WAREHOUSE=your-warehouse ``` ::: :::accordion{title="BigQuery"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} BIGQUERY_PROJECT_ID=your-project-id BIGQUERY_DATASET_ID=your-dataset-id BIGQUERY_CREDENTIALS={"type":"service_account","project_id":"..."} ``` ::: :::accordion{title="ClickHouse"} ```env theme={"theme":{"light":"github-light","dark":"vesper"}} CLICKHOUSE_URL=https://your-instance.clickhouse.cloud:8443 CLICKHOUSE_USERNAME=default CLICKHOUSE_PASSWORD=your-password CLICKHOUSE_DATABASE=default ``` ::: :::: ## Example Queries Once your data is stored, you can run analytics queries. Here's an example to get email status counts by day: :::code-group ```sql PostgreSQL theme={"theme":{"light":"github-light","dark":"vesper"}} SELECT DATE(event_created_at) AS day, event_type, COUNT(*) AS count FROM resend_wh_emails GROUP BY DATE(event_created_at), event_type ORDER BY day DESC, event_type; ``` ```javascript MongoDB theme={"theme":{"light":"github-light","dark":"vesper"}} db.resend_wh_emails.aggregate([ { $group: { _id: { day: { $dateToString: { format: '%Y-%m-%d', date: '$event_created_at' }, }, event_type: '$event_type', }, count: { $sum: 1 }, }, }, { $sort: { '_id.day': -1 } }, ]); ``` ```sql ClickHouse theme={"theme":{"light":"github-light","dark":"vesper"}} SELECT toDate(event_created_at) AS day, event_type, count() AS count FROM resend_wh_emails FINAL GROUP BY day, event_type ORDER BY day DESC, event_type; ``` ::: :::callout{intent="info"} See the [queries\_examples.md](https://github.com/resend/resend-webhooks-ingester/blob/main/queries_examples.md) file in the repository for more analytics queries including bounce rates, open rates, and click-through rates. ::: ## Data Retention By default, webhook events are stored indefinitely. To implement data retention policies, you can set up scheduled jobs to delete old events. Example for PostgreSQL (delete events older than 90 days): ```sql theme={"theme":{"light":"github-light","dark":"vesper"}} DELETE FROM resend_wh_emails WHERE event_created_at < NOW() - INTERVAL '90 days'; ``` :::callout{intent="tip"} For Supabase, use [pg\_cron](https://supabase.com/docs/guides/database/extensions/pg_cron) to schedule cleanup queries. For MongoDB, consider using [TTL indexes](https://www.mongodb.com/docs/manual/core/index-ttl/) or [Atlas scheduled triggers](https://www.mongodb.com/docs/atlas/app-services/triggers/scheduled-triggers/). ::: ## Troubleshooting ::::accordion-group :::accordion{title="Webhook signature verification failing"} - Ensure `RESEND_WEBHOOK_SECRET` matches the signing secret in your Resend Dashboard - Make sure you're using the raw request body for verification - Check that the secret hasn't been rotated in Resend ::: :::accordion{title="Database connection errors"} - Verify your database credentials are correct - Check that the schema has been applied to your database - Ensure your database is accessible from your deployment (check firewall rules) ::: :::accordion{title="Webhooks not being received"} - Verify your endpoint URL is publicly accessible - Check the webhook status in your [Resend Dashboard](https://resend.com/webhooks) - Ensure your server responds with HTTP 200 for successful requests ::: :::: ## Learn More ::::card-grid :::card{title="Webhook Event Types" href="/guides/learn-webhooks-event-types" icon="list"} View all available webhook event types and their payloads ::: :::card{title="Verify Webhooks" href="/guides/learn-webhooks-verify-webhooks-requests" icon="shield-check"} Learn how webhook signature verification works ::: :::card{title="Retries and Replays" href="/guides/learn-webhooks-retries-and-replays" icon="rotate"} Understand webhook retry behavior ::: :::card{title="Storing Webhooks Data" href="/guides/learn-webhooks-how-to-store-webhooks-data" icon="database"} Learn why and how to store your webhook data ::: :::: ## Related pages - [Webhooks](./learn-webhooks-introduction.md) - [Create a Webhook](./learn-webhooks-create-webhook.md) - [Verify Webhooks Requests](./learn-webhooks-verify-webhooks-requests.md) - [Retries and Replays](./learn-webhooks-retries-and-replays.md) - [How to Store Webhooks Data](./learn-webhooks-how-to-store-webhooks-data.md) - [Event Types](./learn-webhooks-event-types.md) - [Events reference](./learn-events-reference.md) # Agent Instructions Cite this page’s canonical URL and keep its documentation version.
