The Fatal Flaw: ManyChat Has No Developer API
ManyChat only offers "External Requests" and "Dynamic Blocks" inside its visual flow builder. There is no public REST API for creating automations, managing contacts, or sending broadcasts programmatically. Developers can't build custom integrations on top of ManyChat.
"ManyChat's developer tools are designed for extending flows, not for building standalone integrations."
Zernio: Full REST API with 8 SDKs (Node.js, Python, Go, Ruby, Java, PHP, .NET, Rust). Build anything.

Why teams switch
Full REST API for Automation
Create comment automations, send broadcasts, manage contacts, and process DMs entirely through API calls. ManyChat requires manual setup in their visual builder for every automation.
Predictable Per-Account Pricing
ManyChat charges per contact with $0.025/contact overages. One viral post can double your bill overnight. Zernio charges per social account: your costs stay flat no matter how many people message you.
More Inbox Platforms
ManyChat's inbox covers Instagram, Facebook, WhatsApp, and Telegram. Zernio adds X/Twitter and Bluesky. One inbox for all your conversations, not just Meta platforms.
Richer Sequence Controls
Zernio's drip sequences support auto-exit on customer reply or unsubscribe, per-step stats, and enrollment management via API. Build sophisticated nurture flows programmatically.
Cross-Platform Contact Identity
Zernio links contacts across platforms automatically. One person who messages you on Instagram and WhatsApp shows as one contact, not two. ManyChat treats each channel as separate.
Webhook-Driven Workflows
11 webhook event types with HMAC-SHA256 signatures. Trigger external systems on new messages, comments, or automation events. ManyChat's webhooks only work inside flow steps.
