Introduction into API Types

Comparing REST APIs, GraphQL, Webhooks

Popular Choice


They are stateless, cacheable client-server communication interfaces that adhere to the constraints of the REST architectural style. REST APIs are a popular choice due to their simplicity and ease of integration with HTTP.

Query Language


Sometimes confused with APIs, GraphQL is an open-source data query and manipulation language (API Query Language) developed by Facebook, providing clients the power to request their exact data needs. This makes it feasible to aggregate data from various sources, boosting performance on the client-side.

Respond to Events


They offer real-time data delivery, making web applications respond quickly to events. Triggered by a specific event -- such as updating a customer’s details in a database or a new sign-up -- webhooks provide instant data push mechanism which makes them an essential tool in creating real-time applications.

Each has their benefits and the choice between them really depends on your individual project needs, scale, and long-term goals. At Pacific Codeline, we ensure to assist you in making the best decision tailored to your business requirements. With our proficient team, you can rest assured that the API choice, its development, and integration will flawlessly align with and propel your business objectives.
