We have an secondary (not NAV) system on an on-premise server. It would accept API calls from an old NAV application from our second on-premise server. The secondary application would only accept this as it was restricted by IP.
If we move to Business Central SaaS, can we still identify the source of an API call coming from Business Central? Does SaaS only send API's from a specific list of IP addresses or FQDN?
Equally, does Business Central reject any calls made to it, or would it be happy to accept calls from anywhere?
Thank you.
