Dynamic IP Update API
Some registrars like Namecheap offers updating IP address to support Dynamic DNS via API.
When a client who purchases a domain through reseller using WHMCS, this feature is not available to them, putting the re seller using WHMCS at a disadvantage, as they cannot use the WHMCS account to dynamically update the IP.
It would be good to provide a proxy using the WHMCS account of the user to dynamically update the IP using the registrar's API called by WHMCS.
Client Server ---> dynamic IP API to WHMCS ---> WHMCS uses the reseller's ID to update the IP using registrar's API
