Upgrade to Contis API V2 from API V1

This page is dedicated to help Contis clients who are currently using the older version of Contis APIs (V1), upgrade to the new standard offering RESTful APIs (V2).

History of API V1

Contis APIs V1 were launched back in 2013 with an aim to enable Contis clients to use APIs for self-serve portals and applications. These APIs were developed using XML based SOAP technology protocol and until the launch of V2, they served all client needs. There were 240+ methods supported, and they powered various actions on the Contis platform.

Introduction of API V2

Contis APIs V2 were launched in 2018 and they support more than 350+ methods, covering various functionalities and scenarios on the Contis platform. Contis API V2 is a RESTful API and a JSON based data format to communicate between client and Contis servers. V2 was developed with the latest authentication method of OAuth 2.0, which is an open standard for authorisation commonly used as a way for Internet users to log in to third party website accounts without exposing their password.

What are the advantages of API V2?

Contis V2 APIs are open to access via VPN and certified PKI security. In the PKI based version Payload will be covered with an end-to-end security on public networks. This is the same for VPN Payload, which will be routed via a secure tunnel communication between the Contis and client servers. Contis V2 APIs allows you to develop a mobile App without developing a wrapper between the App and Contis API. Contis API V2 calls can be cached and data can be marked as cacheable, which can be reused by the browser later without having to initiate another request back to the server. This saves time and resources.

How to begin with migration activity?

  1. List all V1 methods that you are using.
  2. Create mapping of V2 methods against your V1 methods.
  3. Create copy of your source project code and start using V2 APIs in development environment.
  4. Ensure your system supports toggle between V1 and V2 (On/OFF configuration based behavior).
  5. Test V2 APIs in your new source code and ensure they are working perfectly.
  6. Do Sandbox testing (Beta environment).
  7. Do Pre-Production testing (Staging environment).
  8. Inform Contis your go-live plans/schedules.
  9. Contact Contis API support when required during the whole process.
