Getting "HTTP Error 400. The request URL is invalid" error ,when I click on exam voucher link

Hi Vivek,

Thank you for contacting the Microsoft Community.

Allow me to provide information regarding the challenge you've attended.

If you are referring to the Microsoft Build May 2023, please be aware that you will be entitled to a voucherless discount that can be claim starting on June 30, 2023, and expires on September 27, 2023.

You may redeem your discount at the said timeframe.

In case this is from the Microsoft Virtual Training Day, please be advised that the MVTD discount offer has already been discontinued since March 28, 2023. The recently concluded events and upcoming schedules for the training has no longer include vouchers, as you may have noticed in the event description and confirmation email you received, with discounts not being mentioned.

For your reference, here’s a snip of the “Thank you” email for the previous MVTD discount offer:

The above sample email covers steps in redeeming the discount, while the “Thank you” email you received no longer covers the discount since this offer has already ended.

While this is true, you may want to consider participating in the ongoing Microsoft Build | Cloud Skills Challenge promotion and earn one free Microsoft Certification eligible exam.

You may also visit the Microsoft Events Catalog for upcoming training and promotions.

Otherwise, if it’s from a different Microsoft event, please provide us with sufficient details through private message such as, link where this was offered/obtained, and email confirmation on the event attended to verify the redemption guidelines. To access your private message, please refer to the image below:

I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages.

Regards,

Hi Vivek,
