What are the Atlas Application Services?

Install the Atlas Device SDK

Device Sync uses the SDK's native language objects to define a data model and work with data. Everything you need to add sync to your app is included in the Atlas Device SDK.

To install the SDK, see the SDK documentation for your language and platform.

Enable and Configure Sync

In your Atlas App, enable Device Sync and define read and write permissions to control the data that users can sync. Once Sync is turned on, you can start syncing from any app with the SDKs.

To enable Sync, see Enable Atlas Device Sync.

Read and Write Synced Data

Data that you subscribe to with the SDK is automatically kept in sync with your Atlas cluster and other clients. Apps keep working offline and deterministically sync changes whenever a network connection is available.

To learn how to read, write, and subscribe to data, see the SDK documentation for your language and platform.

Enable the Data API CRUD & Aggregation Endpoints

The MongoDB Atlas Data API lets you read and write data in Atlas using HTTPS requests. Once enabled, you can use a built-in endpoint to work with data.

See Data API Endpoints.

Define Custom Endpoints

You can tailor your API with custom endpoints for your application. Each endpoint handles incoming HTTPS requests for a specific route and returns configurable HTTPS responses.

See Custom Endpoints.

Secure Your API

Generate an API key that you can use to authenticate requests. Alternatively, you can use other authentication provider credentials associated with your app.

For details, see Data API Authentication.

Send a Data API Request

Send requests from any server-side environment that supports HTTPS.

curl -X POST \
     https://data.mongodb-api.com/app/<YOUR APP ID>/endpoint/data/v1/action/insertOne \
     -H 'api-key: <YOUR API KEY>' \
     -H 'Content-Type: application/json' \
     -d '{
       "dataSource": "mongodb-atlas",
       "database": "learn-data-api",
       "collection": "hello",
       "document": {
         "text": "Hello from the Data API!",
       }
     }'

Create and Configure Your Trigger

Set up a trigger to respond to events like database operations or user logins as they occur. Or, configure a trigger to run on a periodic schedule. For each trigger type you can define custom conditions to control exactly when the trigger should fire.

To learn more, see Triggers.

Write the Trigger's Handler Logic

When a trigger fires, it passes the event data to a handler that can perform any action you want. You can run a serverless JavaScript function or pass the event to AWS EventBridge.

Fire the Trigger Automatically

Once deployed, the trigger constantly listens for events that it is configured to fire on. When an event causes the trigger to fire, it automatically runs the handler logic you defined.
