Connect Rex and Space Invoices / Apollo
When Appraisal Created fires in Rex, your agent runs Add customer in Space Invoices / Apollo, or New Document in Space Invoices / Apollo to Create Lead in Rex. 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.
