As part of our system improvement project, we have migrated Orderbox API Traffic(i.e httpapi.com,test.httpapi.com) from the legacy server to Cloudflare Argo setup on 12th and 16th September 2021. Over the last few months, while we eased traffic via the new setup, the older legacy infrastructure has continued to receive some hits. This should not happen unless we have some caching issue or if the older IP's are explicitly used in the application code instead of domain name (i.e httpapi.com,test.httpapi.com).
Note that we will be deprecating the legacy server setup completely on 09th March 2022 and post that you will not be able to reach our older legacy server. Therefore, we request everyone to clear system cache or ensure that you connect to our server only via the domain names httpapi.com and test.httpapi.com to ensure uninterrupted API services.
Please reach out to the Support Team if you have questions.
