Connect Handwrytten to 44API
When something happens in Handwrytten, your agent does the next thing in 44API. Describe it in plain language and the automation is built, tested on every branch and kept running.
Build it
What do you want Handwrytten and 44API 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.
