Webhooks, REST, and gRPC is a self-paced, project-driven online course designed for software developers, system integrators, backend engineers, and DevOps professionals who want to master the most in-demand web communication protocols and API integration strategies.
 
In modern application development, seamless communication between systems is critical. This course dives deep into three major paradigms:
  • Webhooks – lightweight HTTP callbacks that enable real-time communication by pushing data instantly between services.
  • REST (Representational State Transfer) – the most widely-used standard for building scalable web APIs using HTTP methods.
  • gRPC (gRPC Remote Procedure Call) – a high-performance, contract-first framework by Google that enables communication between distributed systems using Protocol Buffers.
You’ll start by understanding the fundamentals of how systems interact over the web and progress toward building practical solutions using each of these protocols. The course not only teaches the theory but emphasizes real-world applications and hands-on integration scenarios that professionals face in API-based architectures and microservices environments.
 
What Is Webhooks, REST, and gRPC?
  • Webhooks allow systems to push updates to other systems in real time. They are ideal for event-driven architecture and automation.
  • REST is an architectural style used to design stateless APIs with HTTP. It underpins most modern web services today.
  • gRPC is a language-agnostic, efficient, binary communication protocol that supports streaming and is often used in microservices and internal communications where performance is key.
Together, these technologies empower developers to build robust, reactive, and scalable applications.
 
How to Use This Course
 
This course is structured to build progressively:
  1. Start with foundational concepts of APIs, web protocols, and system-to-system communication.
  2. Practice building and consuming RESTful APIs using tools like Flask, FastAPI, or Node.js.
  3. Dive into Webhooks, configure real-time integrations (e.g., Stripe, GitHub), and build your own Webhook services.
  4. Master gRPC by defining .proto files, generating client-server code, and implementing streaming and unary RPCs in Python and Go.
  5. Complete hands-on projects including event-driven integrations, microservices with gRPC, and hybrid architectures.
  6. Deploy your services, secure them using HTTPS and authentication mechanisms, and monitor them in production.
Each module includes exercises, code-alongs, documentation practices, and projects that mirror professional use cases. By the end of the course, you’ll be job-ready to build, integrate, and scale modern APIs using Webhooks, REST, and gRPC.

Career & Jobs Back to Top
In today’s API-first development landscape, mastering Webhooks, REST, and gRPC opens doors to a wide variety of high-demand job roles. REST remains the dominant paradigm for building external and internal APIs, while Webhooks are increasingly used in real-time automation and event-driven integrations. gRPC, favored by cloud-native companies and microservices architects, is becoming a cornerstone of high-performance distributed systems.
 
Professionals with expertise in these technologies are highly sought after in roles such as:
  • Backend Developer
  • API Integration Engineer
  • Cloud Native Developer
  • DevOps Engineer
  • Microservices Architect
  • Full Stack Developer (with strong backend focus)
Companies building scalable platforms—especially those in fintech, e-commerce, SaaS, healthtech, and cloud infrastructure—look for developers proficient in API integration, microservices, and real-time communication. Freelancers and consultants can also benefit greatly, as Webhooks and REST integrations are commonly requested in client projects involving Stripe, Slack, Shopify, GitHub, Zoom, etc.
 
This course prepares you to handle real-world API challenges, such as syncing data between systems, building streaming services, and integrating third-party providers in secure and efficient ways. The ability to deploy these services using Docker, secure them with JWT or OAuth2, and monitor them effectively will put you ahead in interviews and client meetings.
Interview Questions Back to Top
1. What is a Webhook and how is it different from an API?
A Webhook is a server-to-server push notification triggered by an event, while an API requires clients to pull data through requests.
 
2. How do you secure Webhooks?
By verifying HMAC signatures, using HTTPS, and validating secret tokens in request headers.
 
3. What is REST and what are its key principles?
REST is an architectural style using stateless communication, uniform interfaces, and resource-based URLs typically over HTTP.
 
4. What are some common HTTP methods used in REST APIs?
GET, POST, PUT, PATCH, DELETE are standard REST methods representing CRUD operations.
 
5. What is gRPC and how does it differ from REST?
gRPC is a high-performance RPC framework using Protocol Buffers and HTTP/2, offering bi-directional streaming and better performance than REST.
 
6. What is a .proto file in gRPC?
A .proto file defines the schema for messages and service interfaces used to auto-generate code in gRPC-supported languages.
 
7. How does gRPC handle streaming data?
gRPC supports client-side, server-side, and bi-directional streaming using HTTP/2.
 
8. When would you use Webhooks over polling an API?
When real-time data delivery is needed and constant polling would be inefficient or expensive.
 
9. How do you monitor and debug gRPC services?
Using tools like Prometheus, OpenTelemetry, and gRPC interceptors for logging and tracing.
 
10. Can REST, Webhooks, and gRPC coexist in a single system?
Yes, they can be combined to create hybrid architectures depending on use cases such as external API (REST), real-time updates (Webhooks), and internal microservices (gRPC).
