Use cases
list (by channel ID)
Code symbol that, when clicked, opens the fullscreen APIs Explorer widget and populates it with values for the 'list (by channel ID)' example for the subscriptions.list method.
This example retrieves a list of channels that the specified channel subscribes to. In this example, the API response lists channels to which the GoogleDevelopers channel subscribes.
list (my subscriptions)
Code symbol that, when clicked, opens the fullscreen APIs Explorer widget and populates it with values for the 'list (my subscriptions)' example for the subscriptions.list method.
This example uses the mine parameter to retrieve a list of channels that subscribe to the authenticated user's channel.
check whether a subscription exists
Code symbol that, when clicked, opens the fullscreen APIs Explorer widget and populates it with values for the 'check whether a subscription exists' example for the subscriptions.list method.
This example determines whether the user authorizing the API request subscribes to the channel that the forChannelId parameter identifies. To check whether another channel (instead of the authorizing user's channel) subscribes to the specified channel, remove the mine parameter from this request and add the channelId parameter instead.

In this example, the API response contains one item if you subscribe to the GoogleDevelopers channel. Otherwise, the request does not return any items.
