I'm trying to perform CAPI using ctwa_clid. I already have the ctwa_clid captured with me but when I try to send it to the graph API I get the error:

""error_user_title": "Message event does not match WhatsApp Business account ID and CTWA CLID."

To do this, I need to link my WhatsApp business account to my Facebook page and then link the pixel.

However, this has already been done on this account. And it is not possible to associate a page that is already associated.

Therefore, I need to detach a page and a WhatsApp business account from a Pixel (data set). But that doesn't seem possible.

How can I unlink a WhatsApp Business account from a page?
