📄️ What is a webhook?
Webhooks, also known as http callbacks, are a way for APIs to notify applications that a specific event has occurred without receiving a request.
📄️ What is a webhook endpoint?
A webhook endpoint is a URL that receives webhook event notifications and can trigger an action based on the payload sent in the message.
📄️ What is a webhook retry?
A webhook retry is an attempt to send a webhook message that has already failed. Webhook retries are a best practice when designing webhook systems to achieve high reliability and deliverability of event notifications.
📄️ What is a webhook URL?
A webhook URL is the URL that you can send an API request to in order to notify the user that a certain event has occurred.
📄️ Webhook Authentication
Webhook authentication is the process of verifying the identity and legitimacy of webhook requests coming from the webhook service to the webhook receiver.
📄️ Webhook Proxy
A webhook proxy is a service that acts as an intermediary between webhook providers and webhook receivers, forwarding incoming webhook requests to the appropriate destination.
📄️ Webhook Signature
A webhook signature is a webhook security mechanism used to verify the authenticity and integrity of webhook messages sent from a provider to a receiver.
📄️ What is a webhook gateway?
A webhook gateway is an intermediary service or component that sits between webhook providers and webhook receivers.
📄️ Webhook Payload
In the rapidly evolving landscape of web development and API integration, webhooks stand out as a powerful tool for enabling real-time data exchange between applications. At the core of this mechanism lies the concept of webhook payloads, a critical component that carries the data transmitted during a webhook transaction. This article delves into the intricacies of webhook payloads, exploring their structure, importance, and effective utilization in various applications.
📄️ Callback URL
Callback URLs play a pivotal role in modern web integrations, providing a means for applications to communicate asynchronously. They are particularly relevant in the context of webhooks, where they serve as the endpoints that webhooks interact with. This article will explore the general use of callback URLs and their specific importance in webhook implementations.
📄️ Webhook Rate Limit
Webhook rate limits are crucial in managing the flow of data between services. These limits serve to maintain service quality, prevent abuse, and ensure equitable resource usage. Both webhook providers and consumers have valid reasons for implementing these controls.
📄️ Understanding Webhook Timeouts
Webhooks are a powerful tool used to create real-time applications by sending data triggered by events. However, they are not immune to the limitations of web communications, such as timeouts. This article explores the rationale behind webhook timeouts, what happens when a timeout occurs, and strategies to resolve these issues.
📄️ Exponential backoff
Exponential backoff is an algorithm for limiting attempts by increasing the time delay between attempts exponentially.
📄️ SSRF (Server Side Request Forgery)
Server-Side Request Forgery, or SSRF, is a type of security vulnerability that occurs when an attacker manipulates a web application to make requests on behalf of the server.
📄️ HMAC (Hash-based Message Authentication Code)
HMAC is a specific construction for creating a message authentication code (MAC) involving a cryptographic hash function in combination with a secret cryptographic key. HMAC involves combining a shared secret key with the message data, hashing the result with a cryptographic hash function, and then again hashing that combined with the key. This process provides assurance about the data integrity and the authenticity of a message.
📄️ Dead Letter Queue
A dead letter queue (DLQ) is a secondary queue used in messaging systems to store messages that cannot be successfully processed or delivered by the primary system.
📄️ Message Broker
Definition of Message Broker
📄️ Event Driven Architecture
Event-driven architecture is a software design pattern that revolves around the production, detection, and reaction to events.
📄️ Event Types
Webhooks are user-defined HTTP callbacks that are triggered by specific events in a source application. They are a means for different web services to communicate and transfer data in real-time. Understanding the types of events that can trigger webhooks and their uses is crucial for automating workflows and integrating disparate systems.
📄️ Event Broker
An event broker is a middleware component in event-driven architectures, that facilitate routing events from publishers (entities that emit the events) to subscribers (entities that listen for and react to the events). They ensure efficient processing and distribution of events and support complex routing, event transformation, and processing logic.
📄️ SQS Visibility Timeout
As a software engineer, ensuring reliable and efficient processing of messages in distributed systems is crucial. Amazon Simple Queue Service (SQS) is a fully managed message queuing service that facilitates decoupled communication between services. One of its key features, Visibility Timeout, plays a pivotal role in message processing reliability.
📄️ Priority Queue
As a software engineer, you often encounter scenarios where certain tasks or requests must be processed with varying degrees of urgency. A priority queue is an essential data structure that allows you to handle such cases efficiently, ensuring high-priority tasks are attended to before others.
📄️ Distributed Message Queue
As a software engineer, you frequently face the challenge of building scalable, fault-tolerant systems that can process vast amounts of data while maintaining high performance. Distributed message queues address this challenge by enabling asynchronous communication between services, promoting decoupling, and ensuring resilience in modern distributed architectures.
📄️ Background Queue
As a software engineer, you’ve likely encountered situations where certain tasks in your application are slow or computationally expensive—such as sending emails, processing images, or generating reports. Running these tasks during a user’s interaction with your system can lead to poor performance and degraded user experience. Enter background queues, a mechanism for offloading tasks to run asynchronously in the background, enabling your application to stay responsive while handling heavy lifting behind the scenes.
📄️ Distributed Message Broker
As a software engineer, you often encounter the challenge of designing systems that can reliably handle large-scale message processing across distributed environments. Distributed message brokers play a pivotal role in enabling decoupled communication, scalability, and fault tolerance in such architectures. Whether you’re building a real-time streaming platform, event-driven microservices, or IoT applications, distributed message brokers form the backbone of modern distributed systems.
📄️ Quorum Queue
As a software engineer, you’re always striving to design systems that are both reliable and robust, especially when it comes to message delivery. Ensuring messages aren’t lost due to node failures, network interruptions, or unexpected disruptions is critical. This is where quorum queues come into play. They offer a durable and fault-tolerant solution for message storage and delivery in distributed messaging systems. In this guide, we’ll explore quorum queues, their use cases, and how to implement them effectively using RabbitMQ.
