API and Page ID (beyond frustrating)

I’m the account owner and admin and I’ve created multiple booking pages including one created just for the sake of testing. I’m using the /v1/profiles API with Basic Auth (my Account ID and API Key), but I consistently get an empty array or missing profiles.

I’ve confirmed:
• I’m logged in as the owner
• The API key is new and belongs to the account
• The pages were created under this account
• I can book successfully through the frontend

Can you please confirm:
• Why /v1/profiles is not returning these pages?

I’ve reviewed all previous similar enquiries, and in every case the responses provided were incomplete. No one followed up after users sought clarification following vague or unhelpful initial replies. This is extremely frustrating.

Why can’t the system simply display the profile ID within the account dashboard? This level of opacity is, quite frankly, ridiculous.
