Dear StackOverflow Experts,
We have a requirement to access an API from SAP BODS. SAP BODS needs a WADL file configured in order to access the API. The API we are trying to call is a rest services API with a POST method and accepts only JSON parameters as input.
I have tried using SOAP UI to generate the WADL file but the WADL file does not include the JSON input parameters in the file.
Can anyone help me with a sample code of how a JSON input can be specified as a parameter in the WADL file.
I have tried going through all the documentation that is available but could not come across anything that could help.
I am new to API and any help is appreciated.

I need to validate incoming json requests structure in wso2. I will be able to validate incoming json using default json validator in mediation sequence, but I want to apply json validation only for POST request and not for GET request in an API. It can be achieved by adding custom in flow sequence.
I'm having json validator file for schema validation(like jsonvaldiator.json).
Where should I keep this file in wso2 api manager 2.6.0 and how to mention the validator file path in filter added in the custom in flow sequence?
Any comments would be appreciated.
Yes, you need to add a custom In sequence to the default message mediation flow in order to achieve this. Please have a look at this blog post about validating JSON request payload. This might help to do this for APIM-2.6. Because the blog has been written for an older version but you can get the idea. :)

I've been doing research in order to write an API for a school project, and when referencing the API documentation of YouTube and Twitter, I see API URLs like this
https://api.twitter.com/1.1/account/settings.json
My understanding was that you execute a method on the backend which will return information to the caller, but I thought those files had to be of extension type .py or .java or whatever language you're using, and JSON was just the return type. I've been unable to find any information on how a .json file works in this example. Is there code in settings.json that is being executed?
JSON is just a format of your data, that you can then use, for example in JavaScript.
It is back-end language independent. By this I mean, that front-end of the application does not care who produced .json file.
Maybe it was Java application, maybe it was Python, or PHP application it does not matter. It can be also static file, with fixed content which just has json format.
After you receive such thing in front-end, you can do with it whatever you want. From your perspective it will be probably some kind of nested array.
In example you provided, I get:
{"errors":[{"code":215,"message":"Bad Authentication data."}]}
And it is fine, it's just data you get. It is JSON format - that is true. But you don't care that path has .json in the URL, it could have any extension, what is important is what's inside.
That is a beauty of JSON. You can prepare for yourself static file with mocked data in JSON format, and use it while developing front-end of the application. When you wish, you can have back-end application which will return real data for your app.
You can also see here, how to return json file from PHP:
Returning JSON from a PHP Script
Or here to see how to do it in Python (Django Framework):

How to call a rest service that returns JSON in a APIKit based message flow. I want to prepare the request for Rest service and want to extract the JSON message in a message flow.
Can any one help me to do this?
Thanks
The recommended way to invoke/consume REST services in mule is the use of HTTP Request
Do let us know if there is a specific you are facing
The request connector is especially handy when consuming a RESTful API
that is described in a RAML file. If you reference the API's RAML file
in the connector's configuration, it will proactively offer you the
set of available resources and operations contained in the RAML file,
as well as enforce the policies described in the file. It will also
expose the API metadata to Studio, which can then be used by other
elements such as DataWeave to autocomplete fields and make
configuration much easier
Use Rest URI path to invoke the Service and you can also get json response as output based on the type of service you invoke
I am new to wso2 API Manager, trying to set it up expose my plain HTTP POST back end calls as a REST API. I am sure this is not a new pattern that I am trying to achieve here. The requirement is to convert the JSON data coming in (has array structures) into the HTTP URL query string parameters.
After some research through the documentation and other posts on this forum, decided to go with the script mediator that would parse the JSON data and convert it to a string that can be appended to the endpoint URL. Some how I am not able to achieve this.
I have followed the following post that seems to be very straight forward. As the original poster suggested, I am also not able to use getPayloadJSON() method. Even have trouble using the work around suggested there due to JSON.parse() not working.

Also, this approach of editing the service bus configuration from source view does not sound like the correct option. Is there another elegant solution to achieve this? Thanks for the help in advance.
I was able to get both methods working by using an external script instead of the inline java script. Thanks
I am trying to pass the data from the database to the controller through a service (WCF Data Service), which is an independent application. While running the service for testing, the data is shown in XML format. I need to view the data in JSON format. Any solutions??
Thanks in Advance
For JSON support:
Download the JSONPSupportBehavior.cs from the Microsoft Code Gallery
Locate the JSONPSupportBehavior.cs file in the downloaded project and include it in your web project.
Add a reference to System.Runtime.Serialization.dll.
Mark your service with the JSONPSupportBehavior attribute.
[JSONPSupportBehavior]
public class WcfDataService : DataService<SampleDbEntities>
Please refer this link
A Beginner's Tutorial for Creating WCF Data Services
Hope this helps
WCF Data services supports JSON out of the box.
In order to receive a response in JSON format, you can include application/json in the accept header of the request. Or you can use $format=json in your request url.
