Architecture

Nexio APIs use the REST (Representational State Transfer) architecture for simplicity and scalability. REST uses HTTP methods (GET, POST, PUT, DELETE) and exchanges data in formats like JSON or XML.

We have provided an outline of all the API endpoints and connections in the API diagrams topic.

Security

To get started with the Nexio APIs, you need a Nexio username and password for an API user. Contact Integrations Support to request credentials, if needed.

For many of the Nexio endpoints, you must provide your authentication information for an API user. See each endpoint for more information on the required authentication. The form of authentication required for each endpoint is listed in an "Authorization" section at the top right panel of each endpoint reference.
