Node server SDK
The server SDK wraps the Management API. It uses the secret key, so it belongs on your server and never in a client bundle.
How it works
- 01
Install the Node package on your server.
- 02
Create a client with your secret key from the environment.
- 03
Upsert campaigns, build segments, or trigger a send now.
Questions
What is the difference between the public and secret key?
The public key is write-only and safe in an app: it can identify users and record events. The secret key unlocks the Management API — campaigns, segments, audience counts and send-now — and must stay server-side.
