INVALID_REQUEST_PARAMETER creating an envelope with notifications - docusignapi

Question

I'm trying to create an envelope with an EventNotification, so that I don't have to poll for the status once every 15 minutes.
Making a request to create an envelope without notifications works fine, so it's definitely something to do with the eventNotification part of the request.
Here is the full request:
{
"emailSubject": "Test Sending Envelope 2",
"eventNotification": {
"envelopeEvents": [
{ "envelopeEventStatusCode": "sent" },
{ "envelopeEventStatusCode": "delivered" },
{ "envelopeEventStatusCode": "completed" },
{ "envelopeEventStatusCode": "declined" },
{ "envelopeEventStatusCode": "voided" }
],
"includeCertificateOfCompletion": "true",
"includeCertificateWithSoap": "false",
"includeDocumentFields": "true",
"includeDocuments": true,
"includeEnvelopeVoidReason": "true",
"includeSenderAccountAsCustomField": "true",
"includeTimeZone": "true",
"loggingEnabled": "true",
"recipientEvents": [
{ "includeDocuments": "Sent" },
{ "includeDocuments": "Delivered" },
{ "includeDocuments": "Completed" },
{ "includeDocuments": "Declined" },
{ "includeDocuments": "AuthenticationFailed" },
{ "includeDocuments": "AutoResponded" }
],
"requireAcknowledgment": "true",
"signMessageWithX509Cert": "false",
"url": "https://arealurl/api/DocuSign-NotificationWebHook",
"useSoapInterface": "false"
},
"status": "sent",
"templateId": "template-guid-4b95-guid-template",
"templateRoles": [
{
"email": "someone#somewhere.com",
"name": "Someone Somewhere",
"roleName": "Something"
}
]
}
And the error that comes back is:
Error calling CreateEnvelope: {
"errorCode": "INVALID_REQUEST_PARAMETER",
"message": "The request contained at least one invalid parameter. Boolean value expected for parameter: includeDocuments"
}.
I have tried with the includeDocuments value being omitted, with it set to a string "true", and also with the boolean true as shown above.

Answer 1

The recipientEvents property is incorrect. Change includeDocuments to recipientEventStatusCode
"recipientEvents": [
{ "recipientEventStatusCode": "Sent" },
{ "recipientEventStatusCode": "Delivered" },
{ "recipientEventStatusCode": "Completed" },
{ "recipientEventStatusCode": "Declined" },
{ "recipientEventStatusCode": "AuthenticationFailed" },
{ "recipientEventStatusCode": "AutoResponded" }
],
