API access is available to users on the Professional plan or higher. You can provision and manage API keys from your dashboard: https://app.targetsmarter.com/settings/api-keys Each key is tied to your account and subject to your plan’s usage limits. Keep your API keys secure. Do not expose them in client-side applications.

​
Base URL

Authentication

All API endpoints require authentication using a Bearer token. Include your API key in the Authorization header of every request: 
Authorization: Bearer YOUR_API_KEY
Authentication is defined globally in the OpenAPI specification and is automatically applied in the Try It playground. 
"security": [
  {
    "ApiKeyBearer": []
  }
]
If authentication is missing or invalid, the API will return a 401 Unauthorized response.
