A .NET (Standard 2.0) client library to connect with researchnow/ssi demand api
See complete API reference here

• Account credentials to access researchnow/ssi demand api
• Or, a test account to explore the API on UAT server

The host URLs are configured while creating the client connection, described in the next section.

Prod settings:

• Authentication endpoint: "https://api.researchnow.com/auth/v1/token/password"
• API base url: "https://api.researchnow.com/sample/v1"

UAT (default) settings:

• Authentication endpoint: "https://api.uat.pe.researchnow.com/auth/v1/token/password"
• API base url: "https://api.uat.pe.researchnow.com/sample/v1"

The new client is initialized with production or UAT environment using SamplifyEnv parameter value in the constructor as described below:

• SamplifyEnv.UAT
• SamplifyEnv.Prod
• SamplifyEnv.CheckProcessEnv
  • Environment variable env could be set to "uat" or "prod". If none found, default "uat" value will be used.

SamplifyClient client = new SamplifyClient("client_id", "username", "password", SamplifyEnv.UAT);

The session expires after some time but the client will automatically acquire one by making an authentication request before sending out the actual request, again.

All the request functions are async Task<T> type and return their respective response objects with the Task. All those returned, response object types are derived from ResearchNow.SamplifyAPIClient.Response type. The response returned, consists of:

• Requested data object.
• HasError property to determine if the request executed successfully.
• ResponseStatus, which consists of:
  • API custom status related to the request's execution.
  • ErrorInfo array, containing un-marshaled error data from API response.
  • Http ErrorResponse object, containing http error code, url etc. in case of any error.

Some of the response objects (such as those that return a list) also contain a "Meta" field.

• Meta, contains metadata such as page navigation links etc.

private async void btnGetAllProjects_Click(object sender, EventArgs e)
{
    var r = await client.GetAllProjects(null);
    if (!r.HasError)
    {
        foreach (var p in r.Projects)
        {
            // ...
        }
    }
}

In the above example, the await operator is applied to GetAllProjects (async) method. To enable the await keyword, btnGetAllProjects_Click event handler is defined by using the async modifier.

All client functions that take QueryOptions parameter, support filtering/sorting & pagination. Nested fields are not supported for filtering and sorting operations. Default limit value is set to 10 but values up to 50 are permitted.

var options = new QueryOptions(10, 5); //offset=10, limit=5

options.AddFilter("title", "Test Survey");
options.AddFilter("state", StateConstants.Provisioned);

options.AddSort("createdAt", SortDirection.Asc);

var r = await client.GetAllProjects(options);

If multiple sort objects are provided, the order in which they are added in the list, is followed. Following is a list of filtering/sorting field values:

• id
• extProjectId
• extLineItemId
• createdAt
• updatedAt
• title
• name
• text
• type
• state
• stateReason
• stateLastUpdatedAt
• isoCode
• countryName
• countryISOCode
• languageISOCode
• launchedAt

• public async Task<ProjectResponse> CreateProject(ProjectCriteria project)
• public async Task<ProjectResponse> UpdateProject(ProjectCriteria project)
• public async Task<BuyProjectResponse> BuyProject(string extProjectID, BuyProjectCriteria[] buy)
• public async Task<CloseProjectResponse> CloseProject(string extProjectID)
• public async Task<GetAllProjectsResponse> GetAllProjects(QueryOptions options)
• public async Task<ProjectResponse> GetProjectBy(string extProjectID)
• public async Task<ProjectReportResponse> GetProjectReport(string extProjectID)
• public async Task<LineItemResponse> AddLineItem(string extProjectID, LineItemCriteria lineItem)
• public async Task<LineItemResponse> UpdateLineItem(string extProjectID, string extLineItemID, LineItemCriteria lineItem)
• public async Task<UpdateLineItemStateResponse> UpdateLineItemState(string extProjectID, string extLineItemID, string action)
• public async Task<GetAllLineItemsResponse> GetAllLineItems(string extProjectID, QueryOptions options)
• public async Task<LineItemResponse> GetLineItemBy(string extProjectID, string extLineItemID)
• public async Task<GetFeasibilityResponse> GetFeasibility(string extProjectID, QueryOptions options)
• public async Task<GetCountriesResponse> GetCountries(QueryOptions options)
• public async Task<GetAttributesResponse> GetAttributes(string countryCode, string languageCode, QueryOptions options)
• public async Task<GetSurveyTopicsResponse> GetSurveyTopics(QueryOptions options)
• public async Task<bool> RefreshToken()
• public async Task<bool> Logout()

Supports API functionalities, such as:

• Authentication, including automatic re-authentication on token expire.
• Project and Line Items related requests. Such as, create, update, get-all, get-by-id requests etc.
• Filtering & Sorting
• Pricing & Feasibility
• Data endpoint functions, serving attributes, categories and countries & languages data.
