# Fetch or upload your GSTR-2B

> Pull your 2B straight from the GST portal with an OTP, or upload a 2B file you have already downloaded.

There are two ways to bring the portal's data in. Fetching is recommended, because the data comes straight from the source with no file handling.

## Fetch from the portal

<Steps>
  <Step title="Click Fetch GSTR-2B">
    In the **GSTR-2B** section of the setup panel.
  </Step>

  <Step title="Enter your portal username">
    A Portal Authentication box appears. Enter the **Username** for that GSTIN on the GST portal. Tick **Save details for future use** if you do not want to type it every time.
  </Step>

  <Step title="Request and enter the OTP">
    Click **Request OTP**. The portal sends an OTP to the registered mobile number. Enter it and click **Verify & Fetch Data**.
  </Step>
</Steps>

You see "OTP verified successfully", and the system pulls your 2B month by month. Each month shows the number of invoices fetched as it completes. This is the same data you would see on the portal, now inside AI Accountant.

## Upload a file instead

If the OTP is not handy, click **Upload GSTR-2B** and upload the 2B file you have already downloaded from the portal.
