Why Connectly?
Easy integration
Connect via REST in minutes using your API key. No low-level protocol work, no hosting overhead — Connectly manages the WhatsApp Cloud API connection for you.
High throughput
Messaging endpoints support 200 requests/second with burst capacity up to 1,000 requests/second — enough headroom for large campaign send-outs.
End-to-end encryption
All messages travel over WhatsApp’s encrypted transport. Customer data stays private in transit without any extra configuration on your end.
Rich messaging
Send images, video, audio, documents, location pins, interactive list messages, reply buttons, and carousels — not just plain text.
AI agents
Drop Sofia AI or a custom Agent Graph bot into any conversation flow to handle inbound questions, qualify leads, and hand off to human agents automatically.
24/7 support
Connectly’s engineering and support teams are available around the clock across every time zone to help you resolve issues and optimise delivery rates.
Key use cases
How it works
1
Get your API key
Every request is authenticated with an
X-API-Key header scoped to your business account. Generate one from the Connectly Dashboard at any time.2
Send your first message
Use the template message endpoint to initiate a conversation with a customer. Templates are pre-approved by Meta, so they can be sent at any time — no prior interaction needed.
3
Reply within the session window
Once a customer messages you back, a 24-hour window opens. During that window, use the session message endpoint to send free-form replies — no template required.
4
