The java version of wiremock supports Post-serve actions mentioned here http://wiremock.org/docs/extending-wiremock/.
By using this we can send request to a specific URL after serving mocked response to a request. Is it possible to with wiremock.net? if yes, can we configure it via JSON and does it support authentication?

You are looking for a hook / callback which will be triggered after the response has been returned?

Yes. Hook/Callback would be generic. So, that we can do something like this https://blog.jdriven.com/2020/10/using-wiremock-in-an-async-environment/

But in addition, if we can have some predefined post-serve hook like sending request to URL and surface it via JSON configuration, so that one can configure it via JSON mapping files then it would be great. Although I am not sure is it possible to inject stub code here in json config file or not because most people will need some mechanism to get actual token and send in Auth header.

Something like below:

{
    "Request": {
            "Url": "/api/v1/checkin",
            "Methods": ["post"],
            "Body": {
                  "Matcher": {
                        "Name": "JsonMatcher",
                        "Pattern": {
                    "messageId": "mockMessageId409"
                },
                        "IgnoreCase": true
                     
            }
        }
    },
    "Response": {
            "StatusCode": 409,
            "Body": "{\"errors\":[{\"code\":\"wrong_checkin\",\"message\":\"messageId : {{JsonPath.SelectToken request.body \"$.messageId\"}} conflicted\"}]}",
            "UseTransformer": true,
            "Headers": {
                  "Content-Type": "application/json"
               
        }
    },
    "PostServe": {
        "Request": {
            "Url": "http://auditmyoperation.com",
           "Method" : "Post",

             "Authorization": " skslsljd ",
             "Content-Type": "application / json"
           },
           "Body": {
             "messageId": "{{JsonPath.SelectToken request.body \"$.messageId\"}}"
           },

@StefH commented on GitHub (Mar 5, 2021):

Dear @samiransaha, I did update your question with some code formatting so that it it's better readable.

I think this can be implemented, however it will take some effort.

And maybe instead of letting the user define the content, it's maybe easier to just forward the complete request and response to that callback hook. So that all data is present.

  "Hook": {
        "Request": {
            "Url": "http://auditmyoperation.com",
           "Method" : "Post",
           "Headers": {
             "Authorization": " skslsljd ",
             "Content-Type": "application / json"
           }
    }

Thanks @StefH.
Glad to know.
I think there should be an option to send custom request body while sending request in hook along with the option to send complete request body received the way have mentioned.

I've created a preview nuget on myget:, can you please test vesion WireMock.Net.1.4.7-ci-14761 ?
-- >https://github.com/WireMock-Net/WireMock.Net/wiki/MyGet-preview-versions

Only Body or BodyAsJson is supported. No transformation (yet)

@samiransaha A new version WireMock.1.4.7-ci-14768 should now also support transformation.

Add "UseTransformer": true

Thanks @StefH, I will check it.
Another thing not related to webhook, I wanted to know is it possible to configure delay before sending response via JSON or not sending any response entirely?
Something like this in java version of wiremock http://wiremock.org/docs/simulating-faults/

Can we add Faults like no response at all? Correct me if I am wrong with the exiting Faults I will not be able to add delay before response or completely no response, to simulate server is down. Both are good candidate for fault for integration tests.
Thanks @StefH, sorry I missed that in myget link.

Hi @StefH,

I used following rule it didn't work for me looks like.
I got the response, but the webhook request generation failed.
And I see following error is console. Any Idea?

Very strange, according to WIKI it looks fine. (https://github.com/WireMock-Net/WireMock.Net/wiki/Webhook)

See also this unit tests (819629125c/test/WireMock.Net.Tests/WireMockServer.WebhookTests.cs)

Did you try another address?
