Connect Cellcast and Handwrytten
When New Contact List fires in Cellcast, your agent runs Create Contact in Handwrytten, or Address List in Handwrytten to Create Contact List in Cellcast. Describe the whole flow and it is built, tested on every scenario and kept running.
What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.
Build solutions, not workarounds.
