James_Hood Yep - easy enough to revoke. Equally, using our Pause functionality will also mean no calls to your inverter will be made (apart from disabling the schedules on Pause). No charge or export instructions will be sent by us after that.
I'd also recommend creating different API keys for different integration partners/apps - and name them appropriately, so you can easily work out which key is for what integration and generally is good practice to separate them out this way, and allowing full flexibility.
