SDK Installation

Getting started

JDK 11 or later is required.

The samples below show how a published SDK artifact is used:

Gradle:

implementation 'live.ding:dingsdk:0.8.3'

Maven:

<dependency>
<groupId>live.ding</groupId>
<artifactId>dingsdk</artifactId>
<version>0.8.3</version>
</dependency>

How to build

After cloning the git repository to your file system you can build the SDK artifact from source to the build directory by running ./gradlew build on *nix systems or gradlew.bat on Windows systems.

If you wish to build from source and publish the SDK artifact to your local Maven repository (on your filesystem) then use the following command (after cloning the git repo locally):

On *nix:

./gradlew publishToMavenLocal -Pskip.signing

On Windows:

gradlew.bat publishToMavenLocal -Pskip.signing

SDK Example Usage

SDK Example Usage

Send a code

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

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CreateAuthenticationResponse;
importlive.ding.dingsdk.models.shared.CreateAuthenticationRequest;
importlive.ding.dingsdk.models.shared.Security;
publicclassApplication {
publicstaticvoidmain(String[] args) throwsErrorResponse, Exception {
Dingsdk = Ding.builder()
.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();
CreateAuthenticationRequestreq = CreateAuthenticationRequest.builder()
.customerUuid("cf2edc1c-7fc6-48fb-86da-b7508c6b7b71")
.phoneNumber("+1234567890")
.locale("fr-FR")
.build();
CreateAuthenticationResponseres = sdk.otp().createAuthentication()
.request(req)
.call();
if (res.createAuthenticationResponse().isPresent()) {
// handle response
}
}
}

Check a code

Check that a code entered by a user is valid.

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CheckResponse;
importlive.ding.dingsdk.models.shared.CreateCheckRequest;

.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();

FeedbackResponseres = sdk.otp().feedback()
.request(req)
.call();
if (res.feedbackResponse().isPresent()) {
// handle response
}
}
}

Get authentication status

Get the status of an authentication.

packagehello.world;

importlive.ding.dingsdk.models.errors.ErrorResponse1;
importlive.ding.dingsdk.models.operations.LookupResponse;
importlive.ding.dingsdk.models.shared.Security;

}
}

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 builder method 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

Example

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CheckResponse;
importlive.ding.dingsdk.models.shared.CreateCheckRequest;
importlive.ding.dingsdk.models.shared.Security;
publicclassApplication {
publicstaticvoidmain(String[] args) throwsErrorResponse, Exception {
Dingsdk = Ding.builder()
.serverIndex(0)
.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();
CreateCheckRequestreq = CreateCheckRequest.builder()
.authenticationUuid("eebe792b-2fcc-44a0-87f1-650e79259e02")
.checkCode("123456")
.customerUuid("64f66a7c-4b2c-4131-a8ff-d5b954cca05f")
.build();
CheckResponseres = sdk.otp().check()
.request(req)
.call();
if (res.createCheckResponse().isPresent()) {
// handle response
}
}
}

Override Server URL Per-Client

The default server can also be overridden globally by passing a URL to the serverURL builder method when initializing the SDK client instance. For example:

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CheckResponse;
importlive.ding.dingsdk.models.shared.CreateCheckRequest;
importlive.ding.dingsdk.models.shared.Security;
publicclassApplication {
publicstaticvoidmain(String[] args) throwsErrorResponse, Exception {
Dingsdk = Ding.builder()
.serverURL("https://api.ding.live/v1")
.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();
CreateCheckRequestreq = CreateCheckRequest.builder()
.authenticationUuid("eebe792b-2fcc-44a0-87f1-650e79259e02")
.checkCode("123456")
.customerUuid("64f66a7c-4b2c-4131-a8ff-d5b954cca05f")
.build();
CheckResponseres = sdk.otp().check()
.request(req)
.call();
if (res.createCheckResponse().isPresent()) {
// handle response
}
}
}

Error Handling

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

By default, an API error will throw a models/errors/SDKError exception. When custom error responses are specified for an operation, the SDK may also throw their associated exception. You can refer to respective Errors tables in SDK docs for more details on possible exception types for each operation. For example, the check method throws the following exceptions:

Error Type	Status Code	Content Type
models/errors/ErrorResponse	400	application/json
models/errors/SDKError	4XX, 5XX	*/*

Example

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CheckResponse;
importlive.ding.dingsdk.models.shared.CreateCheckRequest;
importlive.ding.dingsdk.models.shared.Security;
publicclassApplication {
publicstaticvoidmain(String[] args) throwsErrorResponse, Exception {
Dingsdk = Ding.builder()
.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();
CreateCheckRequestreq = CreateCheckRequest.builder()
.authenticationUuid("eebe792b-2fcc-44a0-87f1-650e79259e02")
.checkCode("123456")
.customerUuid("64f66a7c-4b2c-4131-a8ff-d5b954cca05f")
.build();
CheckResponseres = sdk.otp().check()
.request(req)
.call();
if (res.createCheckResponse().isPresent()) {
// handle response
}
}
}

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 builder method when initializing the SDK client instance. For example:

packagehello.world;
importjava.lang.Exception;
importlive.ding.dingsdk.Ding;
importlive.ding.dingsdk.models.errors.ErrorResponse;
importlive.ding.dingsdk.models.operations.CheckResponse;
importlive.ding.dingsdk.models.shared.CreateCheckRequest;
importlive.ding.dingsdk.models.shared.Security;
publicclassApplication {
publicstaticvoidmain(String[] args) throwsErrorResponse, Exception {
Dingsdk = Ding.builder()
.security(Security.builder()
.apiKey("YOUR_API_KEY")
.build())
.build();
CreateCheckRequestreq = CreateCheckRequest.builder()
.authenticationUuid("eebe792b-2fcc-44a0-87f1-650e79259e02")
.checkCode("123456")
.customerUuid("64f66a7c-4b2c-4131-a8ff-d5b954cca05f")
.build();
CheckResponseres = sdk.otp().check()
.request(req)
.call();
if (res.createCheckResponse().isPresent()) {
// handle response
}
}
}

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!
