You do not need to include the "?
in the QueryParameter name. it should look more like cursor
and the body value should be the path to the cursor. See examples below @Rathesh Varadarajan
{
"cursor":"abc123",
"date":"2022-06-23",
"data":[1,2,3,4]
}
$.cursor
-----
{
"metadata": {
"cursor":"abc123",
"date":"2022-06-23"
},
"data":[1,2,3,4]
}
$.metadata.cursor
