Question

What am I doing wrong?
I use a PayPal Payments Pro sandbox test account.

1. I execute DoDirectPayment() where PaymentAction=PaymentActionCodeType.Authorization
2. I receive “Success” and TransactionID
3. I execute DoVoid() where AuthorizationID = TransactionID from step 2
4. I receive "10609 Transaction id is invalid."

The same with DoAuthorization().

1. I execute DoDirectPayment() where PaymentAction=PaymentActionCodeType.Order
2. I receive “Success” and TransactionID
3. I execute DoAuthorization() where TransactionID = TransactionID from step 2
4. I receive “10609 Transaction id is invalid."

Answer 1

Your DoVoid request doesn’t look quite right. You’ve got…

<DoVoidRequest>
  <Version xmlns="urn:ebay:apis:eBLBaseComponents">95.0</Version>
  <AuthorizationID>1R649887J67078538</AuthorizationID>
</DoVoidRequest>
</DoVoidReq>

It should be…

<DoVoidReq>
    <DoVoidRequest>
      <Version xmlns="urn:ebay:apis:eBLBaseComponents">95.0</Version>
      <AuthorizationID>1R649887J67078538</AuthorizationID>
    </DoVoidRequest>
</DoVoidReq>
