I can consume SOAP APIs in my company with wso2 api manager. However when I want to consume REST endpoints I am unable to do so. I keep getting no response.
My endpoints are like such:
GET: http://{server}:{port}/api/broker/{brokerId}
POST: http://{server}:{port}/api/addresscleanse with json payload.
I am not seeing any configuration for the backend point where we can specify that the backend service is expecting json payload or queryparameter. I tried to scan the tutorial section and did not find any thing similar to my need.
Any help would be appreciated.
You can define your resources like below. To specify the message body type of the POST request, you can send Content-Type header.

Just started working on an existing project making use of the Exact Online API.
While I was debugging the project I suddenly only started receiving XML results instead of JSON results from the API. I did not change anything about the endpoints being queried I was just running the existing queries trying to figure some things out.
These are the REST API docs: https://start.exactonline.nl/docs/HlpRestAPIResources.aspx
These are the XML docs: https://support.exactonline.com/community/s/knowledge-base#All-All-DNO-Content-xmlsamplecode
Typical REST API endpoints look like this:
https://start.exactonline.be/api/v1/xxxxxx/salesinvoice/SalesInvoices
Typical XML endpoints look like this:
https://start.exactonline.be/docs/XMLDownload.aspx
I also did not change any settings. I only have access to the tokens and api. I don't have access to the account.
This is an example of an endpoint and query where I previously received JSON but am now receiving XML:
https://start.exactonline.be/api/v1/xxxxxx/salesinvoice/SalesInvoices?$filter=InvoiceID eq guid'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxx'&$select=InvoiceID
I tried this manually with Postman and also using the existing code from the project.
Is there some setting I am unaware of? Am i querying the wrong way? Maybe there have been some changes to the API I am unaware of that aren't listed in the release notes?
Please provide the request header Accept in your HTTP request that specifies what content format you prefer to receive: application/json. The default of Exact Online APIs is XML (but seldom to never used).
I need to configure JSON to JSON transformations with API Manager 2.0 very efficiently.
By default, WSO2 API Manager makes transformations JSON-> XML-> and after processing -> XML->JSON
I'd like to know how can I do so directly in JSON to reduce latencies.
Thank you for your help!!
By default, APIM uses PassThrough transport which does not build your message unless it needs to access your message body. So, your json won't be converted to XML in that case.
For example, if you have configured custom mediation and have a content-aware mediator like <log level="full"/>, APIM has to build (i.e. convert to XML) your message body so that it can log the entire message.
If you don't try to access the message body like that, json will be sent to backend as it is.
I want to generate a rest api in odoo so that it can be used in other languages. I have used below api's
http://URL_with_PORT/{}/xmlrpc/2/common
http://URL_with_PORT/{}/xmlrpc/2/object
but when I validated it using postman it is giving me error.
You don't need the curly braces in the URL. Just send it to the xmlrpc/2/common endpoint, as per...
http://<server:?port>/xmlrpc/2/common
You need to set the verb to POST, and the body to raw with XML.
Then send in the following XML in the form as per the documentation.
<?xml version='1.0'?>
<methodCall>
<methodName>version</methodName>
</methodCall>
This will return the server version info as per the examples used in the External API documentation in an XML response.
Postman isn't the best client to use XML-RPC calls, take a look at XML RPC GUI for developers in Windows?. You have to create a raw request and then send it. Using SoapUI would be much easier.
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
Does JSON messages sent over HTTP in response to a URL request make it REST-compliant?
I believe it is not.
But I am not sure on the detailed reason.
If i have a well-organized website,which responds to URL requests with json representation payload - what does it need to do further to comply with RESTful or JAX-RS?
A simple concise explanation will be much appreciated
There is no restriction regarding the payload of messages in REST and using JSON format in HTTP responses isn't enough to make a service RESTful.
To make short (since it's what you asked for ;-)), what is really important in REST is to respect the HTTP operations (GET, POST, ...) are designed for, the concept of resources and their states (idempotence, ...), leverages headers and status codes, ...
The following link could give you hints about the way to implement a RESTful service / Web API:

Hope it helps you,

JSON is a payload and does not play any role in making your Webservice REST-complaint.
Payload could be XML, CSV, plain text etc etc.
The Webservice will be REST-Complaint when it's following REST protocol (set of rules, not network protocol).
There are up to 4 levels where you can make your REST webservice complaint to.
One of the very basic rules to understand is that - Your Request must not be RPC i.e. you MUST not perform any action using a Payload (Typical SOAP) or URL tunnelling e.g. http://www.example.com/product?id=1234&action=delete
In RESTful world you would define one top level URI for the above. e.g. http://www.example.com/product
and then you will call various URLs to perform other actions.
Such as:
POST - create Data
http://www.example.com/product
Body{ here your payload will describe the Product.}
Assuming you rely on server gennerated product id then return type could be Product Id. Which is again should be set as LOCATION parameter of the return header.
PUT - Update Data
http://www.example.com/product/1234
Body{ here your payload will contain the Product details to change.}
GET - Get Data
http://www.example.com/product/1234
DELETE - Delete Data
http://www.example.com/product/1234
