Passing a value from a feature file into a JSON body in specflow c#

Question

Scenario: Create System X Report
Given I have accessed System x's endpoint
When I make a Post request for the report 7890 with the title Report number 7890
Then I get a response
Then I verify the response

That is my scenario in my feature file, I want to pass "7890" & "Report number 7890" into this JSON body, which is on the post request within the Step Definition.

[When(@"I make a Post request for the report (.*) with the title Report number (.*)"), Scope(Tag = "post")]
    public void WhenIMakeAPostRequest(int report, String reporttitle)
    {
        RestRequest request = new RestRequest("upload_with_associations", Method.POST);
        request.AddHeader("Content-Type", "application/json");
        request.AddParameter("application/json", "report_urn\": \"{report}        " +
            "\"_links\": {\n            \"curies\": title\": \"**{reporttitle}**                 \"href\": \"https://report-service-apps.domain/docs/{rel}\",\n       " +
            "             ,\n        " +
            "    \"get-report-documents\": [\n                {\n                    \"href\": \"/api/report/<report_urn>/documents\"\n             " +
                   ]\n        },\n        \"report_urn\": \"**{report}**\",\n        \"report_source\": {\n          " +
             "          get-report-documents , ParameterType.RequestBody);
        IRestResponse response = client.Execute(request);
        statuscode = response.StatusCode;

    }

So I am passing in the values from the feature file into the step definition and then I am trying to replace the value in the json body as {report}, but I know this is wrong, so how can I pass the values into the json body?

[When(@"I make a Post request for the report (.*) with the title Report number (.*)"), Scope(Tag = "post")]
public void WhenIMakeAPostRequest(int report, String reporttitle)


request.AddParameter("application/json", "report_urn\": \"{report}

Answer 1

Try to use some json serializer, for example Newtonsoft.Json .

1. Create a model (or several models) for the request body
2. Create an instance of that model and apply incoming parameters to that model.
3. Mark properties of that model by attribute `[JsonProperty] and use the name from your json
4. Serialize it and use string instead of existing json string

Answer 2

The idea goes like this

1. Take the parameter from feature
2. Create a templete json with a identifier for dynamic usage
3. Create aa script for read the items as map and replace the identifier by value from feature file Pli will post the code shortly
