Getting Started

Overview of the MNDR public API for managing contacts and sequence enrollments.

The MNDR API lets you manage contacts and sequence enrollments from external systems — e-commerce platforms, CRMs, or any custom integration.

Base URL

All endpoints are prefixed with /api/v1:

https://your-domain.com/api/v1

Quick Start

1. Generate an API key in Settings > Developer
2. Include it in every request as the x-api-key header
3. Start making requests

curl -X POST https://your-domain.com/api/v1/contacts/upsert \
  -H "x-api-key: mndr_your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
  "email": "jane@example.com",
  "firstName": "Jane"
}'
