asp.net - paypal invalid transaction id -


i implementing paypal express checkout functionality in asp.net project requires authorization , voiding or capturing authorized amount. i'm using api of version=104.0.

as far understand whole process, doing correctly:

  • i call setexpresscheckout method actiontype set "authorize" in payment details

    setexpresscheckoutrequestdetailstype reqdetails = new setexpresscheckoutrequestdetailstype(); reqdetails.returnurl = "http://some.url"; reqdetails.cancelurl = "http://some.url"; reqdetails.noshipping = "1"; reqdetails.orderdescription = "you're buy items " + payment.amount.tostring("f"); reqdetails.cpplogoimage = "http://some.ulr/image.jpb"; reqdetails.paymentdetails = new paymentdetailstype[1]; reqdetails.paymentdetails[0] = new paymentdetailstype(); reqdetails.paymentdetails[0].paymentdetailsitem = new paymentdetailsitemtype[cart.lineitems.count]; int = 0; foreach (lineitemmodel li in cart.lineitems) {     paymentdetailsitemtype item = new paymentdetailsitemtype();     item.amount = new basicamounttype();     item.amount.value = li.totalincludingshipping.tostring("f");     item.amount.currencyid = currencycodetype.aud;     item.name = li.productitem.displayname;     item.number = li.productitem.sku;     item.quantity = li.quantity.tostring();     item.description = "";     reqdetails.paymentdetails[0].paymentdetailsitem.setvalue(item, i);     i++; } reqdetails.ordertotal = new basicamounttype() {     currencyid = currencycodetype.aud,     value = payment.amount.tostring("f") }; reqdetails.paymentdetails[0].paymentaction = paymentactioncodetype.authorization; reqdetails.paymentdetails[0].paymentactionspecified = true; setexpresscheckoutreq req = new setexpresscheckoutreq() {     setexpresscheckoutrequest = new setexpresscheckoutrequesttype()     {         version = "104.0",         setexpresscheckoutrequestdetails = reqdetails     } };
  • it goes fine , in back-end of paypal in notification test personal account can see message amount of money autorized

  • then call doexpresscheckout. here code of request

    doexpresscheckoutpaymentreq payreq = new doexpresscheckoutpaymentreq() {     doexpresscheckoutpaymentrequest = new doexpresscheckoutpaymentrequesttype()     {         version = configurationmanager.appsettings["paypalapiversion"],         doexpresscheckoutpaymentrequestdetails = new doexpresscheckoutpaymentrequestdetailstype()         {              token = token,              payerid = payerid,              paymentdetails = new paymentdetailstype[1]         }     } };            payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentaction = paymentactioncodetype.authorization; payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentactionspecified = true; payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0] = new paymentdetailstype(); payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0].paymentaction = paymentactioncodetype.authorization; payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0].paymentactionspecified = true; payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0].ordertotal = new basicamounttype(); payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0].ordertotal.currencyid = currencycodetype.aud; payreq.doexpresscheckoutpaymentrequest.doexpresscheckoutpaymentrequestdetails.paymentdetails[0].ordertotal.value = total.tostring("f");

  • this request returns "success" too. save response's doexpresscheckoutpaymentresponsedetails.paymentinfo[0].transactionid future use

  • but when run doauthorize transaction id previous response, "failure". here request code:

    doauthorizationreq authreq = new doauthorizationreq() {     doauthorizationrequest = new doauthorizationrequesttype()      {         version = "104.0",         transactionid = docheckouttransactionid     } }; authreq.doauthorizationrequest.amount = new basicamounttype(); authreq.doauthorizationrequest.amount.currencyid = currencycodetype.aud; authreq.doauthorizationrequest.amount.value = total.tostring("f");

the response says "failure" , errors array contains 1 item errorcode=10609 , message "invalid transaction id"

do have thoughts why happening?

thanks lot!

to capture funds after authorization need run docapture, not doauthorization.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
