Paypal api – PayPal PayFlow Pro Auth Failure

In case anyone wants to see exactly how I changed Postman and .net to work. Thanks again to Preston PHX!

Text Body: PARTNER=PayPal&VENDOR=&USER=&PWD=&TRXTYPE=S&AMT=40&CREATESECURETOKEN=Y&SECURETOKENID=

.Net Code:

private string GetSecureToken(string amount, string trxtype)
{
var secure = new SecureTokenRequest(true)
{
    PARTNER = PartnerId,
    VENDOR = VendorId,
    USER = User,
    PWD = Password,
    AMT = amount,
    TRXTYPE = trxtype
    //CREATESECURETOKEN is set by boolean in SecureTokenRequest constructor
    //SECURETOKENID is set in SecureTokenRequest constructor using new Guid to string
};

var client = new RestClient(Uri);

var request = new RestRequest(Method.POST);

var parameterDict = new Dictionary<string,string>()
{
    {nameof(secure.PARTNER), secure.PARTNER},
    {nameof(secure.VENDOR), secure.VENDOR},
    {nameof(secure.USER), secure.USER},
    {nameof(secure.PWD), secure.PWD},
    {nameof(secure.TRXTYPE), secure.TRXTYPE},
    {nameof(secure.AMT), secure.AMT},
    {nameof(secure.CREATESECURETOKEN), secure.CREATESECURETOKEN},
    {nameof(secure.SECURETOKENID), secure.SECURETOKENID},
};

var parameterList = parameterDict.Select(kvp
    => $"{kvp.Key}={kvp.Value}").ToList();

var postBody = string.Join("&", parameterList);

request.AddParameter("text", postBody, ParameterType.RequestBody);

var response = client.Execute(request);

var responseContent = response.IsSuccessful
    ? response.Content
    : $"{response.StatusCode} : {response.ErrorMessage}";

return responseContent;
}
