# On-Demand Updates

## On-Demand Updates API - Testing <a href="#on-demand-updates-api---testing" id="on-demand-updates-api---testing"></a>

On-Demand Updates API performs a **one-time lookup** for the most recent Account Updater status without enrolling the card for ongoing updates.

* Real-time updates are supported only for Visa and Mastercard.
* American Express and Discover are not supported for real-time Account Updater lookups.
* This mock does not track future updates and does not enroll the card in Account Updater.

The On-Demand Updates API mock allows you to test real-time card update scenarios for **Visa and Mastercard** cards.

### Testing Steps <a href="#testing-steps" id="testing-steps"></a>

1. **Account Enrollment Type:** Manual Enrollment
2. **Register Cards**: Use the **Create Card API** to register the test cards listed in the table below.
3. **Invoke On-Demand Updates API**: Call the **Card Check API** with the cardIDs obtained in step 2 to simulate a card update check.

To test the On-Demand Account Updater endpoint, first set your account to **manual enrollment**. Then, create cards using the test cards listed below and trigger the On-Demand endpoint individually using each card’s `cardID` generated through this process.

**Note:** If you test this with an account set up for **on-create enrollment** and run the On-Demand endpoint using the card IDs from the test cards, the sync response will show an **enrolled** status, and the actual event will be sent to the async webhook URL configured on your VGS dashboard. Therefore, use these test cards only with accounts set up for **manual enrollment**.
