📄️ 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 provider 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)
Hash-based Message Authentication Code (HMAC) is a specific type of message authentication code (MAC) that involves a cryptographic hash function and a secret key.
📄️ 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
A message broker is a middleware that facilitates communication between distributed systems or applications by transmitting messages between them.
📄️ 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.
