The SmartSend Make.com API authenticates each request with a single header:
There are no separate API keys or tokens. Your Organization ID identifies your workspace and authorizes the request.
Treat your Organization ID as a secret. Anyone who has it can send messages and modify conversations in your workspace.

​
Find your Organization ID

Your Organization ID is the workspace identifier shown in the SmartSend app URL when a workspace is active:
If you’re not sure which ID to use, open the SmartSend dashboard, go to your workspace settings, or contact support@smartsend.com.

​
Verify it works

Call the validate endpoint to confirm your Organization ID is correct and that WhatsApp is connected:
If you get Organization not found, double‑check the ID. If whatsappConnected is false, connect WhatsApp in the dashboard before sending messages.

​
Using it in Make.com

When you set up a SmartSend module (or a generic HTTP module) in Make.com, add a header named x-organization-id with your Organization ID as the value. Every call in your scenario reuses it.

Next: send your first message
