I am wanting to be able to Sync this with another CRM tool that has open APIs - and potentially trigger actions if a 'category' or 'tag' is set in that platform.

So - I see that nimble is really just a display info in nimble (if I have this right) and I see Salesforce as the other option. Have I missed something here - or do you have this API capability to allow complete sync between tools and other platforms. Deal breaker if not.
