I have two scenarios for the following API URL.
POST http://{{ip_port}}/oauth/token
When I put the user name and password correctly, it should return
200 and mock json response.
When I put user name and password incorrectly, it should return 401 and mocked json(error).
In Postman Mock server, I noticed that there is no matching algorithm logic for request param.
I want to filter by request param and return related mock responses. I don't want to add two URLs(/token and /failedtoken) for above scenarios.
Currently Postman only support three logic for matching algorithm logic.
Properly formatted responses
HTTP method
Filter by URL
Is there any way to add only one URL for many scenarios in Postman Mock Server?
Postman Mock Server now supports matching by request body. You can use it by specifying a custom header (x-mock-match-request-body to true).
You can also check out an example that demonstrates how this feature works by going to New->Templates and searching for Request Body Matching.

I'm trying to leverage Postman's mock server feature to mock an API that my application calls.
This is a Post request. I have gone through the documentation and as advised I have saved the responses as examples.
When I try hit the mock URL I get the postman error response
Here is my setup -
My Collection with saved examples
MY mock server
After going through your query, I can see that you're trying to match an example based on the body passed with the request.
To match an example based on the request body, you can leverage the body matching feature of mock servers by:
Enabling the body matching feature from the mock edit page (Reference: https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/setting-up-mock/#matching-request-body-and-headers).
OR
Passing an additional x-mock-match-request-body header with value as true along with your mock request to get the desired results.
You can find more information on how to use body matching feature with mock servers here: https://learning.postman.com/docs/designing-and-developing-your-api/mocking-data/matching-algorithm/#6-check-for-header-and-body-matching.
Do let me know if this doesn't solve your issue. In that case, it would be helpful if you can share the mock request that you're sending to get the response.
In my postman mock server I would like to use data from the request. Is this possible? I can't seem to find any reference to this scenario.
For example, my request includes a documentId value. I would like to capture that value and use it in the response.
Thanks.
Postman supports capture of URL path parameters for use in the response body, so e.g. if your example has https://my.example.com/v1/users/{{user_id}} in the URL, then you can use {{user_id}} in the response.
That's about as far as it goes though. You can't at present use data from query parameters, headers or the request body in your responses.
If you need to use other types of request data in your mock responses, you might want to check out MockLab. I've written up a detailed comparison of Postman mock servers and MockLab including a specific on dynamic responses and request data.
I have an API gateway which is a kind of url shortner, it accepts all
the get requests and return the long url associated with that short
url path. example
input GET => xxx.com/abc
return => aaa.com/blablablabla
I want to implement some validation on this so that I don't get
unnecessary junk requests based on path with a regular expression
suppose path should start with "a" in incoming request xxx.com/abc
How can I do that via api gateway request validator, any help
You better try Lambda Authorizer for requests validator.
Your Lambda function will have 2 main tasks
Validate the URL of the request.
Validate the request's Auth header.
Lambda supports various of languages: Python3, Go, Java, Node.js ... so you are freely to use ReGex to filter your requests.
Reference: https://docs.aws.amazon.com/apigateway/latest/developerguide/configure-api-gateway-lambda-authorization-with-console.html
I am trying to write automated tests with Postman. I am new to postman automation world so sorry if the question will seem dumb.
In the api that I need to test when I send a request I immediately receive a response with a transactionID, no matter transaction succeeded or not. Along with my request I send a CallbackURL to the server where I expect the actual transaction result to be called back. The server will do a PUT request back to the CallbackURL that I have provided with the transactionID and the actual response or error.
So the question is, can I have such kind of scenarios in my postman tests?
I guess I should run a web server and expose an endpoint which will expect a PUT request and I should get the body of this PUT request in my tests to check it, and respond back to it with success.
In other words, within my script I need to perform the following actions:
Do a request to the server passing a callback URL
check the immediate response from the server and keep the returned transactionID
Have a webserver run with an endpoint that I passed as a callback URL
Expect a request to that endpoint with transactionID and actual response
Check that the response is what I actually expected
Respond to the request with success
I was thinking about Postman Mock server, but seems it is not designed for such usage.
I also think may be I can run some JS Webserver (may be nodeJS) inside the postman Sandbox...
Actually I am very new to postman testing and I am really confused about this kind of issue. Is it even possible to do this with postman or I need something else?
There are some features provided by POSTMAN which can help you to resolve your problem
When you do request to server passing callback URL it gives you transactionID in response. Save that transactionID in environment variable or global variable. Same you can do it for callbackURL.
Eg. pm.environment.set("transactionID", transactionID);
Then you can do the second request where you passed callback URL and transactionID which you have already.
In short in POSTMAN there are features like
Set global and environment variable which helps to pass some values fetched from response to another request.
call other request on success of first request
eg. postman.setnextRequest({{requestname}});
If you can mentioned your problem statement little bit in details it will be easy to answer in better way.
Hope This Will Help You
I try to send an HTTP POST request to a service endpoint using Play2/Scala WS API. Since there is no parameters to be sent in the HTTP POST body, how can I send it using
WS.url("http://service/endpoint").post()
I have tried post() without argument but it gave me an error.
Cannot write an instance of Unit to HTTP response. Try to define a
Writeable[Unit]
Can you please help on this ?
thanks in advance...
Since post awaits a value that implements the Writeable and ContentTypeOf type classes,
you can use the Results.EmptyContent from play.api.mvc. (See API)
So I guess
WS.url("http://service/endpoint").post(Results.EmptyContent())
should do. (Didnt test)
For Play 2.6 and after, you have to use play.api.libs.ws.EmptyBody.
import play.api.libs.ws.{EmptyBody, WSClient}
WS.url("http://service/endpoint").post(EmptyBody)
Typical error is:
Cannot find an instance of play.api.mvc.Results.EmptyContent to WSBody. Define a BodyWritable[play.api.mvc.Results.EmptyContent] or extend play.api.libs.ws.ahc.DefaultBodyWritables
As of Play 2.8, you cannot use the WSRequest.post(body) methods with an empty body, because the BodyWritable trait requires a non-empty Content-Type
Instead, you can do ws.url(u).execute("POST") to send an HTTP POST request with no body.
