[woocommerce_rest_cannot_view] error for single product triggers

I’m making an automated workflow in Mailerlite that is triggered by the purchase of one specific product. Woocommerce can see Mailerlite (I can surface all of my groups and what not), but Mailerlite cannot see WooCommerce. Why am I getting this error? My API key is correct, I’m put it in the API key textbox about 10 times.
