Integration
Connect Centerflow to The Calendar
When something happens in Centerflow, your agent does the next thing in The Calendar. Describe it in plain language and the automation is built, tested on every branch and kept running.
Build it
What do you want Centerflow and The Calendar to do together?
Describe it and your agent reads both APIs, builds the automation, tests every branch and ships it. The list below is what exists today, not the limit.
Ask the assistant
You'll sign in before anything runs. What you typed comes with you.
Or work from Claude Code
