API Reference - Sendora

Base URL

https://api.sendora.ai

All endpoints in this reference are prefixed with /api/v1/public/.

Authentication

Pass your API key in every request header:

X-API-Key: sk_live_your_key_here

See Authentication for how to generate keys.

Interactive playground

Every endpoint in this reference has a live Try it playground. Enter your API key in the authentication panel (top right) and make real API calls against your production workspace directly from the docs.

The playground uses your real production data. Use an sk_test_ key if you don’t want to affect live campaigns or leads.
