@Spotdirect_dev: Thanks for your question and for providing the request using twurl.
The following error
{
"errors": [
{
"code": "INVALID_PARAMETER",
"message": "Expected Long, got \" 5000\" for bid_amount_local_micro",
"parameter": "bid_amount_local_micro"
}
]
}
is due to the fact that there is a space after the equals sign.
The reason a line item isn’t being created is that it’s not being sent as a POST request. Add the following (after removing the space) to your request and it should work: -X POST.
Hope this helps!
