Explore APIs across four complexity levels, from a five-year-old to a coder, and learn how endpoints and parameter calls fetch information, saving development time and boosting app performance.
Discover what an API is and how endpoints power web services, enabling features like weather data and security APIs, guided by practical examples and rapid API documentation.
Explore public APIs on Rapid API and use their documentation to call endpoints like translate and detect language. Use JavaScript with XML HTTP requests and API key, host headers.
Learn best practices for designing consistent, RESTful interfaces with versioned endpoints, clear error handling, and robust security, including api keys, OAuth, and JWT, rate limiting, documentation, testing, and performance optimization.
Scale and balance your API infrastructure by expanding capacity and distributing requests to multiple servers, ensuring high availability, reduced latency, and resilience through horizontal scaling and load balancing.
Design user friendly APIs by prioritizing consistency, clear naming, predictable responses, and robust documentation with open API specification, versioning, error handling, and authentication to ease adoption and long-term maintenance.
Explore restful design principles for building scalable, maintainable APIs. Identify resources via URIs and manipulate them with standard HTTP methods in stateless requests, using representations like JSON, XML, or HTML.
Learn why API versioning matters and how to implement URL, header, media type, and semantic versioning, ensuring backward compatibility while evolving features with clear documentation and migration guides.
Explore rapid api's marketplace to identify a sellable idea by examining popular APIs, stars, subscribers, and latency. Add a twist to existing ideas and set up for creation and monetization.
Set up a new API from scratch using Express and Cheerio for web scraping, deploy publicly with Netlify, and publish and monetize your API on Rapid API.
Create your own api locally by cloning a repository, installing node and packages like express, axios, and cheerio, then deploy on netlify and publish on rapid api.
Deploy your built API live for free using Netlify's starter plan and GitHub deployment, then publish it on Rapid API for sale to reach users online.
Learn how to publish your deployed API on Rapid API, monetize it with paid plans, and monitor performance with analytics and latency metrics.
Identify common api security vulnerabilities, such as sql injection, csrf, broken authentication, and insecure deserialization. Apply prevention strategies like parameterized queries, input validation, anti-csrf tokens, authentication, encryption, and testing.
Learn rate limiting and throttling to protect APIs, implement token bucket, fixed window, and leaky bucket strategies, and apply policy documentation, retries, monitoring, and role-based limits.
Secure your APIs with authentication, authorization, encryption, input validation, rate limiting, and logging, using OAuth, JWT, and RBAC to protect data, reputation, and compliance.
Web services enable interoperable machine-to-machine communication across networks. Explore soap, rest, and json/xml web services, the http transport, and their role in microservices, mobile apps, and IoT.
Understand three-digit http status codes, from 1xx informational to 5xx server errors, and learn examples like 200 ok, 301 moved permanently, 404 not found, and 500 internal server error.
Master http request methods and their role in client-server communication. Delve into crud, safe and unsafe methods, idempotency, and examples of get, post, put, delete, patch, head, and options.
Troubleshoot and debug http requests with a systematic approach, inspecting status codes, headers, payloads, and server logs using browser dev tools. Leverage Postman, curl, Fiddler, and Wireshark for effective debugging.
Explore request headers and query parameters, their role in authentication, content negotiation, caching, and rate limiting, and learn best practices for secure tokens, validation, and documentation.
Explore the OpenAPI specification, formerly swagger, a rest API description format used to design and document endpoints, operations, parameters, authentication, and formats in YAML or JSON.
Explore Swagger Hub, an online platform for designing and documenting your API using open api specifications, yaml or json, with collaborative versioning, testing, and code generation.
Explore how to document an API with the Open API specification using Swagger Hub, focusing on the info metadata, server base URL, and tag organization for grouped endpoints.
Learn to define API paths and operations in Open API 3.0 with Swagger Hub, covering path syntax, http methods, parameters, query strings, and operation IDs.
Explore open api schemas in swagger hub by defining data models with yaml-based schemas, using types, enums, dictionaries and validation rules to model api endpoints.
Learn what REST APIs are and how representational state transfer enables interoperable, stateless web services using HTTP. Document REST APIs clearly to create well-structured, useful interfaces.
Learn how soap APIs enable cross-platform communication via XML, perform CRUD operations, and be used with languages like JavaScript, Python, and C#. Understand envelope, header, body, and fault structures.
Compare soap and rest apis, where soap is a protocol and rest is an architectural style. Rest is lightweight and stateless, while soap supports stateful tasks like shopping carts.
Understand JSON as a lightweight, language independent data format from JavaScript object notation, ideal for exchanging text data between browser and server using objects and arrays in APIs.
Explore XML, the Extensible Markup Language, and how its extensible, standard markup enables simple, human- and machine-readable data exchange across web services.
Compare XML and JSON for API data exchange, highlighting their structured, self-describing nature, and reveal differences in parsing ease, comments, and browser support.
Explore practical API calls by requesting endpoints with curl or Postman, learn how endpoints behave like links, and set up curl via package managers or downloads.
Learn to fetch stock time-series data in an Angular UI by calling the Info Vantage API with http client, using an API key to compute daily and weekly returns.
Learn to download and use Postman to send HTTP GET requests to public APIs, inspect responses and JSON bodies, manage query parameters and API keys, and save reusable requests.
Learn to make your first api request with curl against a NASA api endpoint, using an api key in the url to fetch the astronomy picture of the day.
Learn all about APIs the easy way!
This course includes all the components of APIs that you need to know about.
APIs are growing fast in popularity due to their major importance in the web space of all the businesses and if you're in IT, it's essential you have knowledge of them, so you can improve your technical abilities and chances to land a good job.
If you are a beginner, or if you have some knowledge of APIs but need to solidify your knowledge overall or on a specific topic, this course is for you. I will carefully explain in detail, starting from scratch all the topics I mentioned before, and your API foundation will be stronger than ever after finishing it.
No programming experience is required, but technical writers with programming experience who want to know more about REST APIs will still find it useful.
Topics covered include:
What's an API
How to call an API
How you can actually make a request to a public API
How to create your own API and sell it
API Good Practices
API Security
API Design
HTTP Requests and Responses
CRUD Operations
RESTful practices
