# Inform challenge result

Once the customer has accepted or rejected the push notification for a 3DS challenge, you can use this endpoint to notify us of the result.

You must call this endpoint before the expiration time, otherwise it will return a 400 error. You can find the expiration information from the 3DS challenge webhook event.

Only the first call to this endpoint will be processed. Any subsequent duplicate requests will be ignored, although you will still receive a success response.
