I run a finance-focused service and I want every account activity—deposits, withdrawals, balance changes—to reach my customers instantly through WhatsApp. The goal is clear: automated, reliable transaction notifications that help me increase trust and ultimately boost revenue. Here’s what I need from you: • Set up or integrate the WhatsApp Business API (or an approved third-party provider) with my current finance database or payment platform. • Build the logic that captures each transaction event and triggers a templated WhatsApp message in real time. • Configure and submit the required message templates so they pass Meta approval. • Provide concise documentation and a short hand-over call so my team can monitor, pause, or edit templates without coding. Acceptance criteria • A test transaction reaches a designated WhatsApp number in under five seconds, showing the correct dynamic data. • At least three templates (credit, debit, balance alert) are live and approved. • Clear setup notes or scripts let us redeploy the integration on a staging server in one step. If you are comfortable with REST APIs, webhooks, Node.js, PHP or Python, and you have shipped WhatsApp solutions before, let’s talk and get this running.
