Instance Method Details

#get_all_images(env) ⇒ Object

Endpoint /images exists on both v1 and v2 API The attribute ‘visibility’ is used to detect if the call has been made on v1 or v2

In case of v2 we have all the needed information, but in case of v1 we don’t and we have to call /images/detail to get full details
