Invalid TransactionID

[MarcDiprose67]

OK, I have been referred here by technical support at paypal, the cannot help me - I am trying to make a chained payment and at first I was receiveng an error for missing trasnsactionID, paykey or trackingID - I dont have a paykey as this is my first call, to attempt to make the payment - herewith the details (I renamed my object to paypalAdaptive as I already have a paypal object in the app).

This is using test payloads from the Github page but I still keep getting the error about the trackingID - I must have the tracking ID in the correct place, as it is finding it and rejecting it.

I can't use PayKey for anything as I cant get that back until I get a correct response - unless I am missing something I should be doing before sending the payload? But the documentation doesnt show this.

I tried a more complex trackingId but still get this,

{"responseEnvelope":{"timestamp":"2016-08-30T07:48:01.180-07:00","ack":"Failure","correlationId":"e5e6d3cbf948","build":"24003818"},"error":[{"errorId":"579051","domain":"PLATFORM","subdomain":"Application","severity":"Error","category":"Application","message":"The trackingId Lesson_400_187106 is invalid","parameter":["Lesson_400_187106"]}],"httpStatusCode":200}

So this is my current code:

var PaypalAdaptive = require('paypal-adaptive');

var paypalSdk = new PaypalAdaptive({
userId: 'm._g',
password: '__',
signature: '_****',
appId: 'APP-80W284485P519543T',
requestFormat: 'JSON',
sandbox: true //defaults to false
});

(no problem there now)

Then this code build the payload:

var payload = {
requestEnvelope: {
errorLanguage: 'en_US'
},
actionType: 'PAY',
currencyCode: 'USD',
trackingId: 'Lesson-400-'+Math.floor(100000+(Math.random()*100000)),
feesPayer: 'PRIMARYRECEIVER',
memo: 'Chained payment example',
cancelUrl: 'https://'+localSubdomain+'.'+req.topLevelDomain+'/cancelPayment',
returnUrl: 'https://'+localSubdomain+'.'+req.topLevelDomain+'/confirmPayment',
receiverList: {
receiver: [
{
email: '[email protected]',
amount: '2.00',
primary:'true'
},
{
email: '[email protected]',
amount: '8.00',
primary:'false'
}
]
}
};

PAYLOAD IS THEN:
{"requestEnvelope":{"errorLanguage":"en_US"},"actionType":"PAY","currencyCode":"USD","trackingId":"Lesson_400_191981","feesPayer":"PRIMARYRECEIVER","memo":"Chained payment example","cancelUrl":"https://_com/cancelPayment","returnUrl":"https://_.com/confirmPayment","receiverList":{"receiver":[{"email":"[email protected]","amount":"2.00","primary":"true"},{"email":"[email protected]","amount":"8.00","primary":"false"}]}}
