I need a complete, end-to-end rollout of the official WhatsApp Business API so I can start running promotional campaigns to my customers as soon as possible. The core of the job is to configure the API through an approved provider (you can recommend the best fit, e.g., 360dialog, Twilio, WATI, or another Meta-verified solution) and connect it to my existing data sources—both CSV uploads and my CRM—so I can push bulk messages effortlessly. Here is what the finished solution must deliver: • Fully activated WhatsApp Business API account, linked to my verified business number. • Bulk-sending capability tied to my customer database with easy import from CSV files and direct CRM sync. • A starter library of message templates (promotions, new arrivals, limited-time offers, updates) submitted and approved by Meta, along with clear instructions so I can add new ones myself later. • Basic automation flows—greeting, opt-in confirmation, auto-reply, and timed follow-up messages—to keep engagement high without manual effort. • A simple campaign dashboard or interface where I can create, schedule, and monitor future sends on my own. • Compliance guidance covering opt-in language, frequency limits, and any other WhatsApp policies that affect promotional traffic. Because my priority is promotional campaigns, speed matters; I’d like everything live ASAP, including a brief hand-over session so I can manage ongoing campaigns independently. When you reply, please outline: 1. The provider or tech stack you recommend and why. 2. A clear timeline with milestone breakdown. 3. Any ongoing costs or subscription fees I should expect. 4. Your fixed or phased pricing for setup and initial training. Once we agree, you’ll get immediate access to the business account details, logo assets, and the current customer list. I’m ready to move fast—let’s get this running.
