An example response from GetChannelFollowers looks like this (per documentation):
{
"_cursor": "1481675542963907000",
"_total": 41,
"follows": [{
"created_at": "2016-12-14T00:32:22.963907Z",
"notifications": false,
"user": {
"_id": "129454141",
"bio": null,
"created_at": "2016-07-13T14:40:42.398257Z",
"display_name": "dallasnchains",
"logo": null,
"name": "dallasnchains",
"type": "user",
"updated_at": "2016-12-14T00:32:16.263122Z"
}
},
...
]
}
The first property in that response is _cursor. Use that value to page more listings.
