Introduction - MoEngage

The MoEngage REST APIs let you manage user data, campaigns, segments, content, and integrations without the dashboard. Every endpoint uses standard HTTP methods, Basic Authentication, and JSON request and response bodies. This reference covers the available API categories, along with the data centers, base URLs, authentication, rate limits, and error handling that apply across them.

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`
DC-101	`https://dashboard-101.moengage.com`	`https://api-101.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

After 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 API requests require Basic Authentication. To authenticate, you must include a Base64-encoded string of your credentials in the Authorization header of every request. Basic Authentication sends a Base64-encoded string containing your username and password with every API request. It encodes a ‘username:password’ string in Base64 and appends the encoded string with ‘Basic ’. This string is included in the authorization header as shown below: {"Authorization: Basic Base64_ENCODED_WORKSPACEID_APIKEY=="}

Required Headers

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

The MOE-APPKEY header (set to your Workspace ID) is required only for File Import APIs and the Test Connection API. It is not required for core Data APIs such as Track User, Get User, Track Event, Merge User, Delete User, and Track Device.

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.

You can perform authentication using a client like Postman as follows:

API Keys by Feature

Different APIs require different API keys from your dashboard:

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

Rate Limits

MoEngage enforces per-workspace rate limits and payload caps on its REST APIs. Requests that exceed a rate limit receive an HTTP 429 response; oversized payloads receive HTTP 413 (or 400). Rate-limited responses include x-ratelimit-limit, x-ratelimit-remaining, and x-ratelimit-reset headers so you can track remaining capacity in real time. For the full per-endpoint breakdown — rate limits, payload size caps, monitoring headers, and how to request an increase — see Rate Limits.

Error Handling

Most MoEngage APIs return errors in the standard format below.

Standard Error Format

{
  "status": "fail",
  "error": {
    "message": "The request parameters are invalid",
    "type": "Bad Request",
    "request_id": "abc123xyz"
  }
}

Newer v5 APIs, such as Flows, use a different error envelope: { response_id, error: { code, message, target, details } }. Refer to the specific API’s reference for its exact error shape.

HTTP Status Codes

Code	Description
`200`	Success
`201`	Created
`202`	Accepted (async processing)

`404`	Not Found - Resource doesn’t exist
`409`	Conflict - Duplicate resource
`413`	Payload Too Large
`429`	Rate Limit Exceeded
