Set up a webhook endpoint using Fastify and Node.js to receive real-time SMS delivery reports from Infobip. This involves creating a Fastify application, validating incoming requests, parsing the payload, and storing the status information in a database. The guide provides a step-by-step process for implementing this.

Infobip delivery reports provide real-time updates on the status of your sent SMS messages, such as whether they were delivered, failed, or are pending. This allows for more accurate tracking than relying solely on the initial API response when sending messages.

Fastify is a high-performance Node.js web framework chosen for its speed and developer-friendly plugin ecosystem. Its efficiency makes it ideal for handling real-time updates from webhooks like those from Infobip.

Use Infobip delivery report webhooks when you need real-time tracking of SMS message statuses beyond the initial API sending response. They are crucial for applications requiring confirmation of delivery or handling failures.

Yes, while the example uses PostgreSQL with Prisma, you can adapt the project to other databases. The provided Prisma schema can be modified to work with MySQL, SQLite, SQL Server, or MongoDB by changing the provider in the schema file.

Verify the signature using an HMAC-SHA256 algorithm with a shared secret configured in your Infobip account and your .env file. The signature is calculated based on the raw request body, so ensure your Fastify setup stores this raw body before parsing the JSON.

Prisma acts as an ORM (Object-Relational Mapper), simplifying database interactions. It's used to define the database schema, manage migrations, and provide a client for querying and storing delivery report data in the database.

Implement robust error handling using try...catch blocks within the webhook handler, especially within database operations. Use Fastify's HTTP error utilities (@fastify/sensible) for clear error responses, and implement logging for tracking issues.

Secure your endpoint by verifying the HMAC-SHA256 signature of incoming requests, using HTTPS, validating input against a schema, and implementing rate limiting to prevent abuse. Proper secrets management and least privilege database access are also essential.

You need a working Node.js environment, npm or yarn, an active Infobip account with API access, database access, a way to publicly expose your server (like ngrok for development), and a basic understanding of JavaScript, Node.js, REST APIs, and webhooks.

The rawBody contains the original, unparsed request body which is crucial for calculating the HMAC-SHA256 signature. Ensure your Fastify application's content type parser stores this raw body before any JSON parsing occurs.

Store sensitive information like the INFOBIP_WEBHOOK_SECRET and DATABASE_URL in environment variables. Never hardcode or commit them to version control. In production, use a dedicated secrets management system.

The provided code handles duplicates using Prisma's upsert functionality, ensuring idempotent database updates based on the unique messageId. This, combined with signature verification, prevents processing unauthorized or unintended duplicates.

The handler processes results in batches using an array. For extremely large batches, consider potential performance impacts on database transactions and optimize accordingly. Ensure your database operations are efficient for handling bulk updates.
