Field Notes
Notes from a team running WhatsApp CRM in production.
No SEO listicles. No “10 ways to boost engagement.” Just writing from engineers, designers, and operators on the BotSync team — about Cloud API quirks, template approvals, AI agent design, pricing economics, and what we've learned from real lead-ops teams across India.

What we write about
Six tracks — each one fed by what we actually work on every day. We'd rather ship one good post a fortnight than fifteen generic ones.
0 live · 2 queued
AI agent design
Account-level prompts, safe-fact guards, handoff heuristics, knowledge-base chunking, hallucination mitigation.
1 live · 2 queued
WhatsApp policy
Template approval patterns, 24-hour window edge cases, opt-out handling, quality-rating recovery.

Why your “agentic” AI keeps hallucinating prices

Reading your WABA quality rating like a doctor reads an ECG

Editorial direction
What this blog is — and isn't
Written by the people who built it
Every post has a named author from the team who shipped the thing — not an outsourced content writer reading docs.
Specific over generic
Real numbers, real configurations, real screenshots from production. No “5 tips to boost engagement.”
Honest about what we don't know
Some posts will say “we tried this, it didn't work, here's what we'd do differently.” That's the writing we want to read too.
India-first context
Templates that get approved here. BSP markups in Indian rupees. WABA quirks that bite mostly Indian numbers. Where context matters, we use ours.
