Requirements

Building the API client library requires:

1. Java 1.7+
2. Maven

Prerequisites

To use GroupDocs.Signature Cloud SDK for Java you need to register an account with GroupDocs Cloud and lookup/create Client ID and Client Secret at Cloud Dashboard. There is free quota available. For more details, see GroupDocs Cloud Pricing.

Install GroupDocs.Signature-Cloud from Maven

Add GroupDocs Cloud repository to your application pom.xml

<repository>
    <id>repository.groupdocs.cloud</id>
    <name>repository.groupdocs.cloud</name>
    <url>https://repository.groupdocs.cloud/repo/</url>
</repository>

Install from source

To install the API client library to your local Maven repository, simply execute:

mvn clean install

To deploy it to a remote Maven repository instead, configure the settings of the repository and execute:

mvn clean deploy

Refer to the OSSRH Guide for more information.

Maven users

Add this dependency to your project’s POM:

<dependency>
    <groupId>com.groupdocs</groupId>
    <artifactId>groupdocs-signature-cloud</artifactId>
    <version>21.11</version>
</dependency>

Others

At first generate the JAR by executing:

mvn clean package

Then manually install the following JARs:

• target/groupdocs-signature-cloud-21.11.jar
• target/lib/*.jar

Get Started

Please follow the Quick Start instructions.

eSign Cloud Document with Image Signature via Java Cloud SDK

// For complete examples and data files, please go to https://github.com/groupdocs-signature-cloud/groupdocs-signature-cloud-java-samples
String MyClientSecret = ""; // Get ClientId and ClientSecret from https://dashboard.groupdocs.cloud
String MyClientId = ""; // Get ClientId and ClientSecret from https://dashboard.groupdocs.cloud

Configuration configuration = new Configuration(MyClientId, MyClientSecret);
SignApi apiInstance = new SignApi(configuration);

FileInfo fileInfo = new FileInfo();
fileInfo.setFilePath("Signaturedocs\\one-page.docx");
fileInfo.setPassword(null);
fileInfo.setVersionId(null);
fileInfo.setStorageName(Constants.MYStorage);

InfoSettings infoSettings = new InfoSettings();
infoSettings.setFileInfo(fileInfo);

SignImageOptions options = new SignImageOptions();
options.setSignatureType(SignatureTypeEnum.IMAGE);

// set signature properties
options.setImageFilePath("Signaturedocs\\signature.jpg");

// set signature position on a page
options.setLeft(100);
options.setTop(100);
options.setWidth(200);
options.setHeight(100);
options.setLocationMeasureType(LocationMeasureTypeEnum.PIXELS);
options.setSizeMeasureType(SizeMeasureTypeEnum.PIXELS);
options.setRotationAngle(0);
options.setHorizontalAlignment(HorizontalAlignmentEnum.NONE);
options.setVerticalAlignment(VerticalAlignmentEnum.NONE);

Padding padding = new Padding();
padding.setAll(5);
options.setMargin(padding);
options.setMarginMeasureType(MarginMeasureTypeEnum.PIXELS);

*set pages for signing (each of these page settings could be used singly)
options.setPage(1);
options.setAllPages(true);

PagesSetup pagesSetup = new PagesSetup();
pagesSetup.setEvenPages(false);
pagesSetup.setFirstPage(true);
pagesSetup.setLastPage(false);
pagesSetup.setOddPages(false);
pagesSetup.addPageNumbersItem(1);
options.setPagesSetup(pagesSetup);

SaveOptions saveOptions = new SaveOptions();
saveOptions.setOutputFilePath("Signaturedocs\\signedImage_one-page.docx");

SignSettings signSettings = new SignSettings();
signSettings.setFileInfo(fileInfo);
signSettings.addOptionsItem(options);
signSettings.setSaveOptions(saveOptions);

CreateSignaturesRequest request = new CreateSignaturesRequest(signSettings);

SignResult response = apiInstance.createSignatures(request);

Authorization & Authentication

Authentication schemes defined for the API is as follows:

JWT

• Type: OAuth 2.0
• Flow: application
• Authorization URL: https://api.groupdocs.cloud/connect/token
