Add a Credit Card

Click on this link to go to WAX and click on "Setup Pay"."setup payment method"

Here are the steps to follow then

If you are still unable to send messages even after registering your credit card, make sure your tax information is correctly completed.

For businesses registered in the EU, the VAT number must be provided, even if it is listed as optional.

Make sure that the selected payment method is set as the default.

(Even if you only have one payment method, it may not be set as the default and could cause issues.)

If It Still Doesn’t Work

Try removing the card and adding it again.

First, re-add the same card, and if the issue persists, try using a different credit card.
