Overview

What the Stynar API is, how it's organized, and where to go next.

The Stynar API lets your application read account and usage data and trigger platform actions — like creating a campaign or connecting a sending account — programmatically, using the exact same logic as the Stynar web app. Nothing is reimplemented separately, so behavior always matches what you'd see clicking the equivalent thing in the app.

API keys

Bearer-token authentication with esk_-prefixed keys, created and managed from Settings → API Access.

51 endpoints

Across 7 API areas — campaigns, templates, leads, meetings, AI, conversations, and sending accounts.

Rate limits & quotas

Per-account limits set individually by Stynar when access is granted.

Tenant isolation

A key can only ever see or act on data owned by the account it belongs to.

API areas

Campaigns — Create, run, and manage outbound campaigns — including their leads, schedule, and templates.
Templates — Reusable email templates, plus Stynar's built-in template gallery.
Leads — Account-wide leads — every lead you have, whether assigned to a campaign or unassigned.
Meetings — Meetings the AI has booked for you, across every campaign.
AI — Reusable AI prompt presets for generating campaign content.
Conversations — The account-wide reply inbox — every conversation a lead has started across your campaigns.
Sending accounts — Connect, verify, and manage the SMTP accounts your campaigns send from.
