Within Azure Logic Apps, is there any way to use JSON Schema validation on the HTTP Webhook callback body? Similarly to how JSON Schema is used on the HTTP Trigger "When a HTTP request is received".
Directly, it does not seem so.
A possible alternative would be to use a Parse JSON component afterwards, but that would not throw a HTTP error when calling the callback url.
Are there any other possible solutions?
Currently, there is no option to do it directly on the Webhook callback. What you can do is to have an intermediate validator HTTP triggered Logic App (Webhook callback wrapper), that does the validation and then forwards the HTTP call to the actual Webhook callback only if valid.
To implement this, you would need to derive a new callback url that points to the intermediate validator Logic App, passing the instanceid in the CallbackUrl. Then you would need to reconstruct the full callback url at the wrapper logic app to forward the validated payload to the original Logic App instance.
You can get some insights on how to implement this Webhook callback wrapper in this post. In your case, as long as you can derive the original callback url on your wrapper/validator, you wouldn't need to store any correlation.
HTH.

I am using postman to get certain responses. Below is my response.
Here I have some other api request links integrated with this response. Is there any possibility that I can get values inside these apis also. Its like retrieve values forom both parent api request and child api request.
I know this is possible using a java code. But is there any other exsiting software that I can use for this?
In your case I would recommend combining multiple requests into a chain or even a workflow. The idea is to have the first request fetch href endpoints that get called in subsequent requests. For that, the initial request needs a post-request test script that reads the href values from the response and stores it in a environment or global variable.
Like so:
// persist project href for next request
pm.environment.set("projectUrlPath", pm.response.json().embedded.elements[0]._links.project.href);
Your next request in the line would than use this variable to build the request url. Like so:
http://www.example.com{{projectUrlPath}}
The key is to correctly navigate to the right attribute in the response json JavaScript object. This online tool might help you with that:

I am exposing an endpoint e.g. example.com/transactions via Apigee. I am using a Proxy endpoint which routes to my Target endpoint.
If I hit xxx.apigee.net/transactions, i get back my entire payload just as if I hit example.com/transactions. So far so good.
However, if I want to view one specific transaction, going to xxx.apigee.net/transactions/1 does not work. How can I make Apigee understand it needs to pass /1 to the underlying proxy endpoint so that it returns the same as example.com/transactions/1?
How can I pass the {resource-path} variable?
The Apigee API gateway passes the value through already. There is no need for additional manipulation.
I've been looking into if it's possible to create a web based version of my Chrome Plugin
now that it's relying completely on Trakt.TV's JSON API.
According to angular's documentation, it's possible to intercept HTTP requests at several levels, one is the HTTP Backend itself (mainly used for testing though) and the other is HTTPInterceptor.get
The basic idea is to wrap calls to Trakt.TV's JSONP api through http://json2jsonp.com/ and have them returned transparently to get around cross site scripting restrictions. This would not only be very useful for my own project, but for a lot of other people daeling with the same issues too (therefore i'll release the module after it's done, but I want to do it properly)
The basics should be simple:
Hook the $http.get request at the right level
Overwrite the original request made
Cancel an optional other request already set up
Hook it through $http.jsonp(http://json2jsonp.com/)
Return the original promise's success/fail when done
Questions:
Has anyone built anything like this yet? (Github searches revealed nothing)
Would you suggest using the HTTPBackend or the HTTPInterceptor?
why can't you just use the jsonp helper function?
httpBakend is a mockup service to fake a backend server is not used on live code. http interceptors would do what you want you just need to attach the callback function name to your request if the url contains what ever name you want to filter and then in the response interceptor you have to pass response to the callback function so the json to be evaluated. be aware that interceptors will inspect every request makde by angular which is not very eficien, unless you are only doing calls to the tv service.
like i said before a better approach is to use $http.jsonp function
https://docs.angularjs.org/api/ng/service/$http#jsonp
a word about interceptors they need to be defined as services and then be passed to HttpProvider during your apps configuration.
As can be seen in AngularJS's source, any $http.post request that returns an HTTP code in the 200-299 range will trigger the success() callback even if the response contains invalid data (like for example invalid JSON).
I'm specifically setting my call's responseType: 'json' and even then the success callback is fired when something else comes back. This is especially annoying in the development server where PHP's display_errors setting is turned on. When something goes wrong server-side and PHP outputs an error message the AngularJS app doesn't detect this and continues happily.
Is there a way to prevent this? I mean, to make the AngularJS app fire the error() callback when the response data is invalid JSON?
Thanks
so your PHP server responds with a 200 error code even on an error? Not knowing PHP, this feels like a server configuration problem to me. I'd expect a 500 error with a payload. That being said, there are two things that I can think of offhand.
$http includes transformResponse handlers you can set up to inspect the response for problems.
$http also includes the concept of "interceptors" which allow you to pick up the response payload and do something with it. You could use an interceptor to "reject" the response.
More information on transformResponse and "interceptors" in the $http documentation:
http://docs.angularjs.org/api/ng.$http
I can't seem to find a definitive answer on this -- what does the p in JSONP stand for?. The candidates I've found so far are padding and prints. Anyone know where the JSONP name came from?
Padding.
from http://en.wikipedia.org/wiki/JSONP
JSONP or "JSON with padding" is a complement to the base JSON data
format, a pattern of usage allowing a page to request data from a
server in a different domain. JSONP is a solution to this problem,
forming an alternative to a more recent method called Cross-Origin
Resource Sharing.
Padding
While the padding (prefix) is typically the name of a callback
function that is defined within the execution context of the browser,
it may also be a variable assignment, an if statement, or any other
Javascript statement. The response to a JSONP request (namely, a
request following the JSONP usage pattern) is not JSON and is not
parsed as JSON; the returned payload can be any arbitrary JavaScript
expression, and it does not need to include any JSON at all. But
conventionally, it is a Javascript fragment that invokes a function
call on some JSON-formatted data.
Said differently, the typical use of JSONP provides cross-domain
access to an existing JSON API, by wrapping a JSON payload in a
function call.
Hope that helped. Google wins!
Stone,
What I know, it stands for 'Padding'. There is a explaination about it on Wikipedia: JsonP
What it does?
It gives you the possibility to make a CROSS-DOMAIN request and get JSON data returned.
Normally via the HTML script tag you call for another JavaScript.
But JsonP provide you a callback function and you can return noraml Json response.
Example:
You create a script tag:
<script type="text/javascript" scr="http://anotherDomain/Car?CarId=5&jsonp=GiveCarResponse"></script>
In this script the GiveCarResponse is the callback function on the other Domain. Invoking this function will result in a Json response. In example:
{"CarId":5, "Brand":"BMVV", "GAS": false}
Does this make sense?
From wikipedia, it stands for "padding" (or with padding).
http://en.wikipedia.org/wiki/JSONP
Umm ... you've seen the wikipedia page, and you mistrust its accuracy?
This standards site seems to confirm the "with padding".
It basically means to add a calling function around JSON.
AJAX can be called from your own server only and is not a cross domain. So to load data from different servers at client side, you make a JSONP request, basically you load a normal javascript file from other server just like you include a normal javascript file. Bust as JSON is not a valid javascript file, JSON is wrapped up in a function call to make it valid js file. the wrapped up function (already in your code) then extracts that data and show it on your page.
