Hi Product Hunt! 👋 I’m Cristiano, the maker behind ZapClient. I built ZapClient after repeatedly facing the same problem: integrating WhatsApp messaging into applications is often complex, fragmented, and hard to scale. Many existing solutions are expensive or not developer-friendly. So I decided to build a developer-first WhatsApp automation API that makes it easy to: • Send and automate WhatsApp messages • Build bots and workflows • Manage conversations at scale • Integrate WhatsApp into apps and systems The goal was simple: make WhatsApp automation as easy as using a REST API. ZapClient is designed for developers, startups, and businesses that want to build messaging products quickly without dealing with unnecessary complexity. I’d love to hear your feedback, ideas, and suggestions. What features would you want in a WhatsApp API? Thanks for checking it out! 🚀
