Big Files, Small Effort: Introducing Async Polling

We’ve added a new way to get your scan results. You can now poll our API for the status of large file scans (up to 5GB), eliminating the need for complex webhook infrastructures. Secure, scalable, and developer-friendly.

Integrating the new polling mechanism is straightforward. Instead of providing a callbackUrl, you provide a traceId and poll the new GET /v1/scan/async/result API endpoint.

Here is a sample implementation using our JavaScript/TypeScript SDK:

import { AttachmentAVApi, Configuration, ResponseError } from '@attachmentav/virus-scan-sdk-ts';
import { randomUUID } from 'node:crypto';
import { exit } from 'node:process';

const config = new Configuration({
  apiKey: '<API_KEY_PLACEHOLDER>'
});

const api = new AttachmentAVApi(config);

const traceId = randomUUID();

async function sleep(ms) {
  return new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
}

await api.scanAsyncDownloadPost({
  asyncDownloadScanRequest: {
    downloadUrl: 'https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf',
    traceId
  }
});
console.log('Async download submitted. Start to poll for scan result...');

let i = 0;
while(true) {
  try {
    console.log('.');
    const scanResult = await api.scanAsyncResultGet({
      traceId
    });
    console.log('Async download scan result:', scanResult);
    exit(0);
  } catch (e: unknown) {
    if (e instanceof ResponseError) {
      if (e.response.status === 404) {
        i++;
        if (i < 10) {
          await sleep(5000);
        } else {
          console.error('Async download scan result not found');
          exit(1);
        }
      } else {
        throw e;
      }
    } else {
      throw e;
    }
  }
}

What’s next?

Apart from small improvements, we are planning to launch our Virus and Malware Scan API in additional regions.
