Squarespace paypal integration issue

[hayli]

Hi there,

I followed the instructions from Squarespace to manually connect paypal business account in Australia to a hosted website.

(https://support.squarespace.com/hc/en-us/articles/115002970367)

However, when I go to connect using paypal merchant ID after granting API access in step 3 it keeps resulting in an error.

Please advise what might be the possible issue here?

Thank you very much.
