List subscriptions message format

List subscriptions requests must be sent as JSON in text frames, one request per frame. This message is different from other as it doesn't require you to provide subscription ID. Thus, the response for this message is different too.

Example of request

_10

{

_10

"action": "list_subscriptions"

_10

}

Example of response

_16

{

_16

"subscriptions": [

_16

{

_16

"subscription_id": "uuid-1",

_16

"topic": "blocks",

_16

"parameters": {

_16

"start_block_height": "123456789"

_16

}

_16

},

_16

{

_16

"subscription_id": "uuid-2",

_16

"topic": "events",

_16

"parameters": {}

_16

}

_16

]

_16

}

If there are no active subscriptions, subscriptions array will be empty.
