The task is to take our brand-new WATI (WhatsApp Business API) account from zero to fully operational. I need the entire environment configured so we can launch marketing campaigns without glitches or delays. Right now nothing is in place, so you will be responsible for building everything—connection to the Facebook Business Manager, number verification, message templates, automations, and any integrations the campaigns depend on. Once finished, I want the system stable enough that messages send and receive instantly and every workflow behaves exactly as designed. Deliverables • End-to-end WATI account configuration, including number activation and Facebook approval • Creation and submission of message templates ready for broadcast marketing campaigns • Automation flows that segment, send, and follow up without manual intervention • Integration points (e.g., CRM, webhooks, or other tools we use) fully tested • Final walkthrough demonstrating a successful test broadcast and error-free message delivery Acceptance criteria – All templates are approved and visible in the WATI dashboard – A sample marketing campaign sends to a test list with 100 % delivery confirmation – Automations trigger correctly on opt-in, click, or reply events – No console errors or misrouted messages for 24 h after hand-over If you have deep, hands-on experience with WATI and can begin immediately, this project should move quickly.
