API Allegro resources are available in two technologies: REST and SOAP.

Our main API that we work on is REST API. Use it when creating a new application or developing features in an existing one. The WebAPI is a legacy solution we only keep in maintenance mode. We no longer develop WebAPI and we will shut it down eventually. All the new features we work on are developed for the REST API only.

REST API recommended

Allegro REST API is based on the HTTP protocol and its methods (GET, POST, PUT, DELETE) and is organised into resources. The authorization is based on OAuth2. We recommend using the REST API.
