Welcome to the MoEngage API reference. Build powerful integrations to automate campaigns, sync user data, manage product catalogs, and deliver personalized experiences at scale.

API Categories

Data Centers

MoEngage maintains multiple data centers. You are assigned to a specific data center when you sign up. You can identify your data center from your Dashboard URL.

Data Center	Dashboard URL	REST API Host
DC-01	`https://dashboard-01.moengage.com`	`https://api-01.moengage.com`
DC-02	`https://dashboard-02.moengage.com`	`https://api-02.moengage.com`
DC-03	`https://dashboard-03.moengage.com`	`https://api-03.moengage.com`
DC-04	`https://dashboard-04.moengage.com`	`https://api-04.moengage.com`
DC-05	`https://dashboard-05.moengage.com`	`https://api-05.moengage.com`
DC-06	`https://dashboard-06.moengage.com`	`https://api-06.moengage.com`

Choosing a Data Center

If you have data privacy requirements to store user data in a specific geographical region:

US region: Sign up with DC-01 or DC-04
EU region: Sign up with DC-02
India region: Sign up with DC-03
Singapore region: Sign up with DC-05
Indonesia region: Sign up with DC-06

Once data is captured in a workspace, it cannot be migrated to a different data center. Always use the REST API endpoint matching your registered data center.

Base URL

All API requests are made to:

https://api-{dc}.moengage.com

Replace {dc} with your data center number (e.g., 01, 02, 03). You can identify your data center from your Dashboard URL.

Each API may have additional path segments (e.g., /v1, /core-services/v1). Refer to the specific API documentation for the complete endpoint path.

Authentication

All MoEngage APIs use Basic Authentication combined with a MOE-APPKEY header.

Required Headers

Authorization: Basic {base64_encoded_credentials}
MOE-APPKEY: {your_workspace_id}
Content-Type: application/json

Generating Credentials

The Authorization header value is a Base64 encoding of workspace_id:api_key.

# Example: Encoding credentials
echo -n "YOUR_WORKSPACE_ID:YOUR_API_KEY" | base64

Getting Your Credentials

Log in to the MoEngage Dashboard
Navigate to Settings → Account → APIs
Copy your Workspace ID and the relevant API Key

API Keys by Feature

Different APIs require different API keys from your dashboard:

API	API Key Location (Settings → Account → APIs)
Data	Data API Key
Push	Push API Key
Inform	Inform API Key
Campaigns	Campaign report/Business events/Custom templates tile
Catalog	Campaign report/Business events/Custom templates tile
Personalize	Personalize API Key

Quick Start

Now that you have your credentials, make your first API request. This example creates a user profile using the Data API.

curl -X POST "https://api-01.moengage.com/v1/customer/YOUR_WORKSPACE_ID" \
  -H "Content-Type: application/json" \
  -u "YOUR_WORKSPACE_ID:YOUR_DATA_API_KEY" \
  -d '{
    "type": "customer",
    "customer_id": "john@example.com",
    "attributes": {
      "name": "John Doe",
      "u_em": "john@example.com",
      "platforms": [
        {
          "platform": "ANDROID",
          "active": "true"
        }
      ]
    }
  }'

Replace api-01 with your data center’s API host (e.g., api-02, api-03).

Expected Response:

{
  "status": "success",
  "message": "Your request has been accepted and will be processed soon."
}

MCP Server

MoEngage provides a hosted Model Context Protocol (MCP) server that connects your AI-powered development tools directly to MoEngage documentation. Instead of searching the web, your AI assistant queries MoEngage docs in real time for accurate, up-to-date answers about APIs, SDKs, and platform features.

Available tools

Your MCP server exposes the following tool:

Tool	Description
`SearchMoEngage`	Search across the MoEngage knowledge base to find documentation, code examples, API references, and implementation guides.

Connect to your AI tool

Cursor
VS Code
Claude
Claude Code

Open MCP settings

Use Cmd + Shift + P (macOS) or Ctrl + Shift + P (Windows/Linux) to open the command palette, then search for “Open MCP settings”. This opens the mcp.json file.

Add the MoEngage MCP server

Add the following configuration to mcp.json:

mcp.json

{
  "mcpServers": {
    "MoEngage": {
      "url": "https://www.moengage.com/docs/mcp"
    }
  }
}

Restart and verify

Restart Cursor, then ask the AI assistant a question about MoEngage. You should see the SearchMoEngage tool listed as available.

In Cursor’s chat, ask “What tools do you have available?” and confirm the MoEngage MCP server appears.

Create the MCP config file

Create a .vscode/mcp.json file in your project root and add:

mcp.json

{
  "servers": {
    "MoEngage": {
      "type": "http",
      "url": "https://www.moengage.com/docs/mcp"
    }
  }
}

Restart and verify

Restart VS Code. The MoEngage MCP server is now available to Copilot Chat.

Open Claude settings

Navigate to the Connectors page in your Claude settings.

Add the MoEngage MCP server

In a chat, select the attachments button (the plus icon).
Select Add.
Enter MoEngage as the name and https://www.moengage.com/docs/mcp as the URL.
Select Add custom connector.

Use in conversation

Ask Claude any question about MoEngage. Claude automatically searches the documentation when relevant.

Run the following command to add the MoEngage MCP server:

claude mcp add --transport http MoEngage https://www.moengage.com/docs/mcp

Verify the connection:

claude mcp list

You can skip manual setup by using the contextual menu on any MoEngage documentation page. Select Connect to Cursor or Connect to VS Code to install automatically, or copy the install command:

npx add-mcp MoEngage https://www.moengage.com/docs/mcp

The MCP server is available for public documentation only. Rate limits apply: 200 requests per hour per user and 1,000 requests per hour across all users.
