Pagination

List endpoints in API v2 use cursor-based pagination with a consistent shape:

{
  "data": [ ... ],
  "meta": {
    "nextCursor": "cursor_value_or_null",
    "hasMore": true
  }
}

Query parameters

Parameter	Type	Default	Description
`cursor`	string	none	Cursor from the previous response (`meta.nextCursor`)
`pageSize`	number	30	Items per page (max 100)

API v2 uses pageSize. Legacy v1 list endpoints use limit instead.

Example

curl "https://api.heffl.com/api/v2/contacts?pageSize=25" \
  -H "x-api-key: YOUR_API_KEY"

Response:

{
  "data": [
    {
      "id": "clt_abc123",
      "number": "CON001",
      "firstName": "Jane",
      "lastName": "Smith",
      "email": "[email protected]"
    }
  ],
  "meta": {
    "nextCursor": null,
    "hasMore": false
  }
}
