LACNIC Registration API

What is an API?

An application programming interface (API) is a set of commands, features and protocols used to integrate different systems without the need to know how they are implemented.

APIs provide flexibility, simplify application design, management and utilization, and create opportunities for new products and innovation.

As APIs have become increasingly popular, specifications have been developed to standardize information exchanges. One such specification is Representational State Transfer (REST). Web APIs that that conform to the REST architectural style are known as RESTful APIs; in simple terms, these APIs use HTTP methods to obtain or manipulate data in various formats, such as XML and JSON.

What is the LACNIC Registration API?

The LACNIC Registration API is a REST-based API that employs Oauth authentication designed mainly for performing bulk management on the resources available through the MiLACNIC platform.

The LACNIC Registration API uses the OpenAPI specification, with a user interface (Swagger-ui) that displays the API's documentation interactively thus allowing users and developers to test their services.
