Linking wordpress to keap

can anyone help re the api code to link wordpress and keap
I keep getting the message saying there appears to be an issue with your credentials !

Also struggling to connect woocommerce on wordpress to keap

It all depends on what you are trying to connect with Keap.

Iif you are looking to connect WooCommerce, you can do that through a tool like Make.com (formerly Integromat), or Zapier, or InfusedWoo. InfusedWoo is my favorite for WooCommerce-specific items, as it is very robust. Make.com and Zapier require a bit more knowledge with coding (not much), but they allow you to do all sorts of things with the data.

Make is my favorite for all other types of integrations.

Thanks,
Jeff
