How a WhatsApp Bot Runs (Architecture)
Yes — and a VPS is the natural home for it. A WhatsApp bot is three pieces talking. Your bot code (Node.js, Python, PHP) holds the conversation logic. Meta's WhatsApp Business Cloud API is the only sanctioned transport, and its webhook calls arrive at your server's HTTPS endpoint whenever a customer messages.
That webhook endpoint is why the VPS matters. It needs a public URL, valid SSL, and a process manager keeping the bot alive across deploys and reboots. PM2 plus Nginx with a Let's Encrypt certificate covers all three on the smallest tier.
Sizing is undemanding — the bot is a webhook server with occasional outbound API calls — so a 1-2 GB RAM VPS carries an India-facing bot comfortably, and the same box can host the CRM or dashboard behind it. The VPS server tiers fit the bill, the Node deployment pattern is the same one Flask and Django use, and the setup steps follow below.

Step 1: Meta Developer App and Credentials
On webhook endpoints (HTTPS), the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.
Step 2: Deploy the Bot With PM2 and SSL Webhook
Deploy the Bot With PM2 and SSL Webhook. Install the certificate on the account that actually serves the site, force HTTPS, then view the page source for http:// images, stylesheets or scripts. The padlock stays broken until those are HTTPS too. Renewal should be automatic; if the padlock disappears, check that the certificate is still bound to this hostname.
Step 3: Test, Templates and Go Live
Two practical notes on always-on VPS: it interacts directly with caching and database response, and misconfiguration is the most common cause of 'hosting is slow' tickets. WebJi® support checks it as part of standard migrations.
