API Overview
MisarMail REST API — send emails, manage contacts, run campaigns, and more
MisarMail API
The MisarMail API lets you programmatically send transactional emails, manage contacts, create campaigns, and access all platform features — the same operations available through the dashboard UI.
Base URL
https://mail.misar.io/apiAll API paths in this documentation are relative to this base. For example, POST /v1/send means POST https://mail.misar.io/api/v1/send.
Versioning
Current version: v1
Routes under /api/v1/ are stable. Breaking changes will be announced and versioned. Routes under /api/ (without /v1/) are session-authenticated UI routes.
Authentication
Two authentication methods:
| Method | Header | Use Case |
|---|---|---|
| API Key | Authorization: Bearer msk_... | Programmatic access, integrations |
| Session Cookie | Automatic (browser) | Dashboard UI |
For programmatic access, always use an API key. See Authentication.
Error Format
All errors return JSON with success: false:
{
"success": false,
"error": "Human-readable error message"
}Validation errors (400) add a details field:
{
"success": false,
"error": "Validation failed",
"details": { "fieldErrors": { "to": ["Must have at least 1 recipient"] } }
}See Error Codes for the full reference.
Plan Limits
All API operations respect the same plan limits as the dashboard UI. A free-plan user cannot create custom domains via API any more than via the UI. See Plan Limits for the full feature matrix.
Quick Start
