Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.

Returns institution_id and product_id for each match, with category, rate and observed_date. A product is the pair (institution_id, product_id): pass both to rate_compare_ratesCurrent comparison across institutions for a product category (home_loan | savings | term_deposit | credit_card | personal_loan | car_loan | business_loan): each product at its own most recent observation (observedDate tells you how fresh). Home loans can be filtered by loanPurporate_historyAdvertised rate history for one product (institutionId and productId).
