Read facebook lead ads - only one lead in response - facebook

Question

I test on https://developers.facebook.com/tools/explorer/
My query: /v2.8/11111111/leadgen_forms?fields=leads_count,leads
Response:
{ "data": [
{
"name": "My Form",
"leads_count": 37,
"leads": {
"data": [
{
"created_time": "2016-12-21T14:50:56+0000",
"id": "10000000000000",
"field_data": [
{
"name": "email",
"values": [
"hidden#gmail.com"
]
},
{
"name": "first_name",
"values": [
"Hidden"
]
},
{
"name": "last_name",
"values": [
"Hidden"
]
}
]
}
],
"paging": {
"cursors": {
"before": "MTc0ODU4Mjg2MjEyODQ1MgZDZD",
"after": "MTc0ODU4Mjg2MjEyODQ1MgZDZD"
}
}
},
"id": "10000000000000"
}
}
Why I get only one lead in data, when I have 37 in leads_count field?

Answer 1

I actually don't see the way you are accessing leads documented anywhere.
In your request, you are accessing the edge of a page, requesting the forms, and within that, requesting the leads.
You should probably be using the edge of the form ID instead to retrieve leads:
curl -G \
-d 'access_token=<ACCESS_TOKEN>' \
https://graph.facebook.com/v2.8/<FORM_ID>/leads
You can also filter them:
curl -G \
-d "filtering=[{'field':'time_created','operator':'GREATER_THAN','value':<TIMESTAMP>}]" \
-d "access_token=<ACCESS_TOKEN>" \
https://graph.facebook.com/<API_VERSION>/<AD_ID>/leads
