We are integrating our zendesk instance with our document management system via API calls. During investigating issues in this interface, we found that our document management setting uses an security setting to compare the IP address in the authentication cookie issued with the IP address from which the request was received. Zendesk however is not limited to sending requests from only one IP address - so there will be API call that are coming from a different Zendesk IP address then the one for which the authentication cookie was issued and these calls are not accepted then by our system.
Are there plans to add a feature to Zendesk support that it will be possible to assign a Zendesk instance with a fixed IP address?
In scenarios like ours described, it would allow the other side to keep the security setting to comapre IP addresses active. Also setting up firewall rules would be much easier for customers if there was only one IP address to consider.
