Having Data API key:secret pairs or some other form of persistent API key would be a great feature and make so many integrations with other services more accessible to more businesses.
The requirement to make an authorization call to FM Data API and then an actual call to read/write data is quite cumbersome as we do not have enough control over outside services, that may only generate a single action for a given event.
I would be happy to see API keys with the ability to configure as Read, Write or Read/Write and have API keys be able to be set for a specific user or a privilege set.
As well an API for creating API keys would be good. This would require a specific privilege set to generate API keys.
