5. Upsert row to a Data Extension

5_UpsertDE.js

//UPSERT DE
var co = {
    "CustomerKey": "7254CCBC-E5F8-49B6-991E-855825DAEADD",
    "Keys":[
        {"Key":{"Name":"subscriberkey","Value":"test@fakeemail.com"}}],
    "Properties":[
        {"Property":{"Name":"color","Value":"purple"}}
      ]
  };

var uo = {
  SaveOptions: [{"SaveOption":{PropertyName:"DataExtensionObject",SaveAction:"UpdateAdd"}}]
};

SoapClient.update('DataExtensionObject',co,uo, function(err, response){
  if(err){
    console.log(err);
  }
  else{
    console.log(response.body.Results);
  }
});

Here is what worked for me.

const updateValues = {
	'Name': 'table_name',
	'Keys': [
		{ "Key": { 'Name': 'Key', 'Value': 'key_value' } }],
	"Properties": {
		"Property": [
			{ 'Name': 'Key', 'Value': 'key_value' },
			{ "Name": "ClientId", "Value": this.thCreds.ClientId },
			{ "Name": "ClientSecret", "Value": this.thCreds.ClientSecret },
			{ "Name": "WorkSpaceId", "Value": this.thCreds.WorkSpaceId },
			{ "Name": "SiteKey", "Value": this.thCreds.SiteKey },
			{ "Name": "BaseUrl", "Value": this.thCreds.BaseUrl }
		]
	}
};

const updateOptions = {
	SaveOptions: [{ "SaveOption": { PropertyName: "DataExtensionObject", SaveAction: "UpdateAdd" } }]
};


this.SoapClient.update(
	'DataExtensionObject',
	updateValues,
	updateOptions
	this.soapRetrieveCallback.bind(this)
);

How can we upsert rows without primary key-value data extension?
