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, which any account can create and manage from Settings → API keys.
72 endpoints
Across 10 API areas — account, billing, campaigns, templates, leads, meetings, AI, conversations, and sending accounts.
Rate limits & quotas
The same default limits for every account, unless Stynar sets custom ones for yours.
Tenant isolation
A key can only ever see or act on data owned by the account it belongs to.
API areas
- Account — Your account's API entitlement, limits, usage, and profile details.
- Billing — Your plan, subscription status, credit balance, and usage against plan limits.
- 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.
- Lead Finder — Search and enrich a licensed people/company database, then import results as leads. Search and reveal calls spend your account's credits, same as an AI-personalized send.
- Meetings — Meetings the AI has booked for you, across every campaign.
- AI — Generate email content and subject lines, browse models and credit costs, or manage reusable prompt presets.
- 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.
