The location key works for some things pertaining to the location. The only tool to create a location without having the agency apu is Zapier. If you think about that - each and every one of your customers - even if they are just users can take the API key, create the location and even steal your snapshots. I have a $37 pipeline pro lifetime account and I can create unlimited pipeline pro locations with their snapshots. I can even take their snapshot and create a location in my agency with their snapshot. Zapier is a HUGE security hole.
