E*Trade API Streaming with CometD - cometd

I have been using a .net library to create an oauth session, and submit, modify and cancel orders using the ETRADE api. Now I need to listen for account & order events. As per the ETRADE API documentation, they use CometD & long poling. I did find a .net CometD implementation. However, the ETRADE API docs says that one must pass some oauthHeader to initialize the CometD session. Does anyone know exactly what that oauthHeader is? Any sample code would be appreciated.

I modified to the oauth .net library to provide the same oauth header that gets passed to other API http requests:
public string GetOauthAuthorizationHeader(string url)
{
NameValueCollection headers = _session.Request(_accessToken).Post().ForUrl(url).GetRequestDescription().Headers;
return headers[Parameters.OAuth_Authorization_Header];
}
Passing this header to cometd works. I did have to change to a different .net commetd library (nthachus's commetd.net), though; the one I was previously using was ignoring these headers.

Does Syncfusion Dashboard web data source support POST http methods?

Does Syncfusion Dashboard web data source support POST http methods?
If yes, so how set it up?
Thanks!
HTTP Post requests additional data from client to server in the message body, where message body will be like JSON, XML, TEXT etc. This may result in the creation of a new resource or the updates of existing resources or both. In contrast, HTTP Get requests include all required data in the URL. So we support HTTP Get method since POST method is not valid use case.

What's the correct uri for QBO v3 API update operation?

I'm trying to use the QBO v3 API object update function described here. The API explorer shows a different uri.
I'm trying to update an account with Id 42. Both of the following URIs get me a 401:
As the documentation would suggest:
https://quickbooks.api.intuit.com/v3/company/0123456789/account?requestid=42
(the above at least gives me a json blob with the 401)
As the api explorer would suggest:
https://qb.sbfinance.intuit.com/v3/company/0123456789/account?operation=update
(here I don't even get the json, just a plain 401)
My request body is successful when I use the api explorer, so I don't believe that's the problem. I also don't believe authentication is the problem, because I can successfully create objects and also make queries with the same headers.
What might I be missing?
Don't put the Account object's ID into the URL. The [?requestid=] from the documentation you mentioned apparently refers to an id related to the request (not the object in question). The API Explorer's URI appears to simply mislead (although I could certainly be missing something here).
In your example, just use this:
https://quickbooks.api.intuit.com/v3/company/0123456789/account
Let the headers and request body do the rest.
Correct BASE URI: https://quickbooks.api.intuit.com/v3/company/
you can refer example request/response section of any entity doc.
Ref -https://developer.intuit.com/docs/0025_quickbooksapi/0050_data_services/030_entity_services_reference/bill
To debug(401 authentication issue), you can use any standard RestClient.
In the following thread, I've explained how to use RestClinet plugin of Mozilla to test any QBO V3 endpoint.
InvalidTokenException: Unauthorized-401
You can download IPP's devkit and using that devkit you can call any endpoints easily.

Hope it will be useful.

Oauth 1.0 with Play framework - get instead of post

I'm implementing access to OAuth service in Play 2.0 application. Generally I'm doing this like described here:
http://www.playframework.com/documentation/2.0.4/ScalaOAuth
Unfortunately the service I'm accessing rejects POST request - which Play sends. Can I change Play's behavior to do GET requests undercover?
Looks like you'll need to write a custom method to handle GET as Play's OAuth object defers request handling to the Commons HTTP library.
Here's a link to the source code for OAuth.scala. Using Play's WS library it should be straightforward to pattern your custom HTTP call based on this:
https://github.com/playframework/playframework/blob/0c265c943a801b2cc9b65e055c956a125f072a64/framework/src/play-ws/src/main/scala/play/api/libs/oauth/OAuth.scala

Getting started with Rally REST webservice API

Was after some help on getting started with calling the Rally REST webservice from a .NET MVC webclient.
I've been given the web service info here:
https://rally1.rallydev.com/slm/doc/webservice/
So I can see that I can use a URL to access information from Rally - Similar to:
https://rally1.rallydev.com/slm/webservice/1.39/task?query=((Owner.Name
= owner#blah.com.au) and (State != Completed))&order=Rank&fetch=true&stylesheet=/slm/doc/webservice/browser.xsl
However what I'm not clear on is how to authenticate before making my request?
I'm new to REST web services (have done the SOAP/WSDL awhile back) - so it doesn't seem like with REST you're supposed to add a reference to something to get client classes created? Is this correct? That you just create a HTTPRequest using a URI - and make the call, getting back a HTTPResponse (which I can hopefully do something with).
A lot of examples seem to have specific service/api classes that they're calling methods on or accessing properties - so I'm not sure if that's because they're using SOAP rather than REST - or that they created them themselves.
Maybe I'm looking at the wrong documentation as it seems assumed you know how to be authenticated. Or I'm missing a reference?
I know the question is old, but this might help someone else. You need to pass a Basic Authentication header with your base64-encoded username and password as part of your get() request. I found this information on an Atlassian documentation page and successfully applied it with Rally API 3.0 (should also work with 2.0). So in your get() request, include a header similar to the following:
auth_header = 'Authorization : Basic ' + base64_encode('username:password')

Consuming a RESTful web service using Apache Camel

I am trying to consume a restful Web service using camel.
For that I am configuring dynamic endpoint url as the RESTful url is created at the runtime. Everytime I am checking if the particular endpoint url is registered as a route in my camel context using following method of CamelContext class.
Endpoint hasEndpoint(String uri);
In this case, if the endpoint is not registered then I add a route to my camel context using a custom Route Builder.
I am using camel HTTP component for this. This is working fine for me as of now.
However, I believe performance wise this is not good as everytime I have to check if a route is registered with the camel context and if not then register the same before making the webservice call.
Can some body please tell me if there is a better way to consume RESTful Web services in camel?
I also want to know if the RESTful webservice I am consuming uses OAuth 2.0 protocol, do I need to change anything in my code as I am just consuming it?
Regards, Nilotpal
Thanks for your reply.
I am checking if the route is already exists to make sure I don't end up adding duplicate route(s) to the camel context.
Regarding long lived routes and route dynamics, can u please explain a bit regarding this? How do I implement route dynamics?
It would also be helpful if you could point me to some CXF-RS producer example.. I read the documentation of CXFRS but could not understand it clearly.
Thanks
Nilotpal
Exactly why do you need to check if the route is registred or not before making the call? You should perhaps setup a more long lived route and route dynamic towards resfull resources.
As for Rest with camel, I think the HTTP component does a great job, but there are higher level components to use as well, more designed for REST.
CXFRS and Restlet, producer examples for restlet can be found in the Apache Camel source unit tests, such as this RestletProducerGetTest.java.
As for oAuth 2.0, Camel has some oAuth support built-in, especially for google. Look for the gauth component. There is even a tutorial, however it might not be aligned with your case, it still might give some background so you could solve your issues: http://camel.apache.org/tutorial-oauth.html
CamelContext context = new DefaultCamelContext();
My Aim
I am trying to intercept the incoming request and based on the ip of the incoming request i want to invoke dynamic endpoint of get offers
context.addRoutes(new RouteBuilder(){
public void configure(){
from("jetty:localhost:9000/offers")
.process(new Processor(){
public void process(Exchange exchange) throws Exception {
//getting the request object
HttpServletRequest req = exchange.getIn().getBody(HttpServletRequest.class);
//Extracting information from the request
String requestIP=req.getRemoteAddr();
/**
* After getting the ip address i do necessay processing
* and then add a property to exchange object.
* Destination ip address is the address to which i want to
* send my request
*/
exchange.setProperty("operatorAddress",destinationIpAddress);
}
})
.to("direct:getOffers")
.end();
}
});
Now i will invoke the getOffers endpoint
so first i will register it
context.addRoutes(new RouteBuilder(){
public void configure(){
from("direct:getOffers")
.toD("jetty:${property.operatorAddress}/api/v2.0/offers?
bridgeEndpoint=true")
.end();
}
});
so we can access the operatorAddress property of exchange object as
${property.operatorAddress}
also when we have dynamic routes then we need to call
.toD() and not .to()
