SDK Example Usage

SDK Example Usage

Send a code

Send an OTP code to a user's phone number.

using DingSDK;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

CreateAuthenticationRequest req = new CreateAuthenticationRequest() {
    CustomerUuid = "cf2edc1c-7fc6-48fb-86da-b7508c6b7b71",
    Locale = "fr-FR",
    PhoneNumber = "+1234567890",
};

var res = await sdk.Otp.CreateAuthenticationAsync(req);

// handle response

Check a code

Check that a code entered by a user is valid.

using DingSDK;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

CreateCheckRequest req = new CreateCheckRequest() {
    AuthenticationUuid = "eebe792b-2fcc-44a0-87f1-650e79259e02",
    CheckCode = "123456",
    CustomerUuid = "64f66a7c-4b2c-4131-a8ff-d5b954cca05f",
};

var res = await sdk.Otp.CheckAsync(req);

// handle response

Perform a retry

Perform a retry if a user has not received the code.

using DingSDK;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

RetryAuthenticationRequest req = new RetryAuthenticationRequest() {
    AuthenticationUuid = "a4e4548a-1f7b-451a-81cb-a68ed5aff3b0",
    CustomerUuid = "28532118-1b33-420a-b57b-648c9bf85fee",
};

var res = await sdk.Otp.RetryAsync(req);

// handle response

Send feedback

Send feedback about the authentication process.

using DingSDK;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

FeedbackRequest req = new FeedbackRequest() {
    CustomerUuid = "cc0f6c04-40de-448f-8301-3cb0e6565dff",
    PhoneNumber = "+1234567890",
    Status = DingSDK.Models.Components.FeedbackRequestStatus.Onboarded,
};

var res = await sdk.Otp.FeedbackAsync(req);

// handle response

Get authentication status

Get the status of an authentication.

using DingSDK;
using DingSDK.Models.Requests;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

var res = await sdk.Otp.GetAuthenticationStatusAsync(authUuid: "d8446450-f2fa-4dd9-806b-df5b8c661f23");

// handle response

Look up for phone number

Perform a phone number lookup.

using DingSDK;
using DingSDK.Models.Requests;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

var res = await sdk.Lookup.LookupAsync(
    customerUuid: "69a197d9-356c-45d1-a807-41874e16b555",
    phoneNumber: "<value>"
);

// handle response

Available Resources and Operations

Available methods

Lookup

• Lookup - Look up for phone number

Otp

• Check - Check a code
• CreateAuthentication - Send a code
• Feedback - Send feedback
• GetAuthenticationStatus - Get authentication status
• Retry - Perform a retry

Server Selection

Select Server by Index

You can override the default server globally by passing a server index to the serverIndex: number optional parameter when initializing the SDK client instance. The selected server will then be used as the default on the operations that use it. This table lists the indexes associated with the available servers:

#	Server	Variables
0	https://api.ding.live/v1	None

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the serverUrl: str optional parameter when initializing the SDK client instance. For example:

Authentication

Per-Client Security Schemes

This SDK supports the following security scheme globally:

Name	Type	Scheme
APIKey	apiKey	API key

You can set the security parameters through the security optional parameter when initializing the SDK client instance. For example:

using DingSDK;
using DingSDK.Models.Components;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

CreateCheckRequest req = new CreateCheckRequest() {
    AuthenticationUuid = "eebe792b-2fcc-44a0-87f1-650e79259e02",
    CheckCode = "123456",
    CustomerUuid = "64f66a7c-4b2c-4131-a8ff-d5b954cca05f",
};

var res = await sdk.Otp.CheckAsync(req);

// handle response

Error Handling

Handling errors in this SDK should largely match your expectations. All operations return a response object or throw an exception.

By default, an API error will raise a DingSDK.Models.Errors.SDKException exception, which has the following properties:

Property	Type	Description
Message	string	The error message
StatusCode	int	The HTTP status code
RawResponse	HttpResponseMessage	The raw HTTP response
Body	string	The response content

When custom error responses are specified for an operation, the SDK may also throw their associated exceptions. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the CheckAsync method throws the following exceptions:

Error Type	Status Code	Content Type
DingSDK.Models.Errors.ErrorResponse	400	application/json
DingSDK.Models.Errors.SDKException	4XX, 5XX	*/*

Example

using DingSDK;
using DingSDK.Models.Components;
using System;
using DingSDK.Models.Errors;

var sdk = new Ding(security: new Security() {
    APIKey = "YOUR_API_KEY",
});

try
{
    CreateCheckRequest req = new CreateCheckRequest() {
        AuthenticationUuid = "eebe792b-2fcc-44a0-87f1-650e79259e02",
        CheckCode = "123456",
        CustomerUuid = "64f66a7c-4b2c-4131-a8ff-d5b954cca05f",
    };

    var res = await sdk.Otp.CheckAsync(req);

    // handle response
}
catch (Exception ex)
{
    if (ex is ErrorResponse)
    {
        // Handle exception data
        throw;
    }
    else if (ex is DingSDK.Models.Errors.SDKException)
    {
        // Handle default exception
        throw;
    }
}

Development

Maturity

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning usage to a specific package version. This way, you can install the same version each time without breaking changes unless you are intentionally looking for the latest version.

Contributions

While we value open-source contributions to this SDK, this library is generated programmatically. Feel free to open a PR or a Github issue as a proof of concept and we'll do our best to include it in a future release!
