more than one field cannot be used to specify a receiver

Question

I'm trying to get delayed chained payments working through PayPal's Adaptive Payments API in C#. The error I'm getting doesn't make any sense and I can't find anything on the .NET to resolve the issue.

The error message is: Invalid request: More than one field cannot be used to specify a receiver

Here's the request I'm sending:

    requestEnvelope.errorLanguage=en_US
    &actionType=PAY_PRIMARY
    &cancelUrl=http%3a%2f%2flocalhost%2fccc%2fProgramsandServices%2fCommunityFundingInitiative%2fOopsSome        thingWentWrong!.aspx ¤cyCode=USD

I specified two receivers, one is Primary other is not.
What am I missing? I've tried both PAY and PAY_PRIMARY as the action types. Same results for either one. If I only use ONE reciever, it works.

Here's the code:

    WebClient webClient = new WebClient();

        // Receivers
        ReceiverList receiverList = new ReceiverList();

        // Primary Receiver
        Receiver receiver = new Receiver();
        receiver.accountId = null;
        receiver.amount = Convert.ToDecimal(txtPledgeAmount.Text.Trim());
        receiver.invoiceId = Convert.ToString(SelectedProjectId) + "|" + Convert.ToString(PortalSettings.AdministratorId) + "|" + Convert.ToString(DateTime.Now.ToUniversalTime());
        //receiver.paymentSubType = null;
        receiver.paymentType = "GOODS";
        receiver.primary = true;

        if (!String.IsNullOrEmpty(PRIMARY_RECEIVER_PHONE_NUMBER))
        {
            receiver.phone = new PhoneNumberType();new PhoneNumberType("001",PRIMARY_RECEIVER_PHONE_NUMBER);
        }
        if (!String.IsNullOrEmpty(PRIMARY_RECEIVER_EMAIL_ADDRESS))
        {
            receiver.email = PRIMARY_RECEIVER_EMAIL_ADDRESS;
        }

        receiverList.receiver.Add(receiver);

        // Secondary Receiver
        string receiverEmail = "";
        string receiverPhone = VALID_PHONE_NUMBER;
        String receiverUserName = MembershipServices.Business.SharedFunctions.GetUserNameEmail(PortalId, SelectedProject.ProjectOwnerID, MembershipServices.SharedEnums.DisplayNameFormat_Type.FullName, ref receiverEmail);
        Receiver receiver2 = new Receiver(Decimal.Parse(this.txtPledgeAmount.Text.Trim()) * SECONDARY_RECEIVER_PERCENTAGE);
        if (!String.IsNullOrEmpty(receiverPhone))
        {
            receiver2.phone = receiver.phone = new PhoneNumberType("001", receiverPhone);
        }
        if (!String.IsNullOrEmpty(receiverEmail))
        {
            receiver2.email = receiverEmail;
        }
        receiver2.primary = Boolean.Parse("false");
        receiver2.invoiceId = Convert.ToString(SelectedProjectId) + "|" + Convert.ToString(SelectedProject.ProjectOwnerID) + "|" + Convert.ToString(DateTime.Now.ToUniversalTime()); ;
        receiver2.paymentType = "GOODS";

        receiverList.receiver.Add(receiver2);

        String PortalAlias = PortalSettings.PortalAlias.HTTPAlias;
        if (!PortalAlias.EndsWith("/"))
        {
            PortalAlias = PortalAlias + "/";
        }

        if (Request.IsSecureConnection)
        {
            PortalAlias = @"https://" + PortalAlias;
        }
        else
        {
            PortalAlias =  @"http://" + PortalAlias;
        }

        string actionType = "PAY_PRIMARY";

        PayRequest req = new PayRequest(new RequestEnvelope("en_US"), actionType,
                            PortalAlias + CANCEL_URL, SharedEnums.CurrencyCode_Type.USD.ToString(),
                            receiverList, PortalAlias + RETURN_URL);

        req.ipnNotificationUrl = PortalAlias + IPN_NOTIFICATION_URL;

        //(Optional) A note associated with the payment (text, not HTML). 
        // Maximum length: 1000 characters, including newline characters 
        if (!String.IsNullOrEmpty(txtPledgeMessage.Text.Trim()))
        {
            req.memo = txtPledgeMessage.Text.Trim();
        }
        else
        {
            req.memo = null;
        }


        // set optional parameters
        //(Optional) Whether to reverse parallel payments if an error occurs with a payment. 
        //Allowable values are:
        //true – Each parallel payment is reversed if an error occurs
        //false – Only incomplete payments are reversed (default)
        req.reverseAllParallelPaymentsOnError = false;

        req.feesPayer = "EACHRECEIVER";

        // Sender's email address 
        =req.senderEmail = SENDER_EMAIL_ADDRESS;

        //(Optional) A unique ID that you specify to track the payment.
        //Note: You are responsible for ensuring that the ID is unique.
        //Maximum length: 127 characters 
        string trackingId = Convert.ToString(SelectedProjectId + "|" + Convert.ToString(SelectedUserId) + "|" + Convert.ToString(DateTime.Now.ToUniversalTime()));
        req.trackingId = trackingId;


        // All set. Fire the request            
        AdaptivePaymentsService service = new AdaptivePaymentsService();
        PayResponse resp = null;
        try
        {
            resp = service.Pay(req);
        }
        catch (System.Exception e)
        {
            Response.Write(e.Message);
            return;
        }

If you've worked through this or can spot the error, please let me know! Thanks.

Answer 1

Removing the phone number fields returns a successful response. I'm not certain if phone number fields are not supposed to be available in a Delayed Chained Payment transaction. I'm going to have to reach out to the product team for Adaptive Payments and find out from them.

Edit: The phone number has to be a confirmed mobile one. The error you're getting is because the phone number field can also be used to define the receiver so you're actually attempting to define the receivers twice.
