Digital Delivery Realtime Data API Example

Overview

This example showcases how to parse a response from the Digital Delivery Realtime Data API.

Pre-requisities

• Digital Delivery application
• Realtime Data API enabled with the Native Storage DATA API type - see Documentation
• Digital Delivery endpoint: {host}/api/query/Messenger/BlobStorageDeltaApiQuery

Cursor Usage Example

// First time we call the API service, we need to provide a timestamp from which we want to list the data.
const date = new Date();
date.setHours(date.getHours() - 24);

const dataApiClient = new RealtimeDataApiClient(dataApiConnector);
const deltaData = await dataApiClient.getDelta(date);

// Save the cursor for the next API call.
const deltaData = await dataApiClient.getDelta(date);
await db.upsert("cursor", deltaData.cursor);

// For subsequent calls, we use the cursor saved from previous call.
const cursor = await db.get("cursor");

const dataApiClient = new RealtimeDataApiClient(dataApiConnector);
const deltaData = await dataApiClient.getDelta(cursor);

Response Parsing Example

const dataApiClient = new RealtimeDataApiClient(dataApiConnector);
const deltaData = await dataApiClient.getDelta(cursor);

for (const item of deltaData.deltaItems) {
    if (item.deltaType === "EmailArchive" && item.customField.startsWith("myJobs")) {
        console.log(item);
    }
}
