Wix Pay API: problem with MercadoPago

I am trying to connect Wix Pay to MercadoPago Argentina. The following text is shown:

  1. Enter your MercadoPago CLIENT_ID and CLIENT_SECRET on the left, and then click Connect My Account below.

I guess you mean MercadoPago username and password. I entered those (they are valid, I checked by login into my MercadoPago account) but I get this error:

There seems to be a problem with the credentials you submitted. Please verify your account details and try again.

Could anyone shed some light onto this?

Forget question, I found the doc. It´s not username and password, but two completely different keys.

Edit: I cannot mark comments as top comments, only when I answer my own questions :slight_smile: I won´t, but maybe you want to have a look at that. Those Top Comments are getting marketing value.
