Ex Libris Developer Network and API Terms of Use

Welcome to the Ex Libris Developer Network. The Developer Network provides a platform for customers of Ex Libris and developers to share code, applications and other content relating to Ex Libris programs and/or services (the “Platform”) through the Ex Libris website located at developers.exlibrisgroup.com (the “Site”). Ex Libris also makes available through the Platform information, resources and/or access to many of Ex Libris’ proprietary product application programming interfaces (each an “API”), an API console, API use data and related documentation and resources (collectively, “API Materials”) solely for non-commercial use by authorized users of such APIs and API Materials in accordance with these terms of use. As used herein, “Ex Libris” means Ex Libris Ltd. and its worldwide affiliates who control, are controlled by or are under common control with Ex Libris Ltd.

By accessing the Site or using the Platform, you agree to be bound by these terms of use (the “Terms”), whether you are a “Visitor” (which means that you are only browsing the Site) or a “Member” (which means that you have registered with the Site). The term “User” refers to a Visitor or a Member. Your use of the Platform and the Site is subject at all times to these Terms (whether as a Visitor or a Member, regardless of whether your access or use is intended). The Site and Platform are always evolving, so it is important that you periodically check here for updates. If we revise the Terms, such revision will take effect immediately upon being posted on the Site. By using the Platform or accessing the Site or any APIs or API Materials you agree to review the Terms periodically to become aware of such revisions. If you do not agree to any of the Terms stated herein, you should discontinue using the Platform, the Site and any APIs and API Materials. Ex Libris reserves the right, in its sole discretion, at any time to modify, discontinue or terminate the Site and the Platform without notice.

For the sake of clarity, the content, code, applications and other materials which are available on the Site are provided separately from Ex Libris programs and services and are not licensed or otherwise provided under a User’s existing license or subscription agreement with Ex Libris for the Ex Libris programs or services provided thereunder. User is responsible for ensuring that it complies with any license or subscription agreement governing Ex Libris programs or services, respectively, and with any terms covering code or applications used by User in connection with such Ex Libris programs or services.

Member Account and Password

In order to contribute and to take advantage of certain features of the Platform, you will have to create an account. When you register for a Member account you will be asked to provide your name, email, organization and a password. You agree that all information submitted to Ex Libris upon registering will be true, accurate, complete and will be kept current. Ex Libris reserves the right to refuse a registration request or to terminate a Member account for any reason. Issues concerning collection and use of your information by Ex Libris are described in Ex Libris’ privacy policy available at http://www.exlibrisgroup.com/privacy-policy. If Ex Libris has grounds to suspect that any information you provide is untrue, inaccurate or incomplete, or in the event of a breach by you of these Terms of Use, Ex Libris has the right to suspend or terminate your account. You agree that Ex Libris may send you important information and notices regarding the Developer Network and your Member account by email.

It is your responsibility to maintain the confidentiality of the account password, and you are responsible for any activities that occur in your account. Ex Libris will not ask you to reveal your password. If you forget your password, you can request to have a new password sent to your registered e-mail address. You agree to indemnify and hold Ex Libris harmless for any unauthorized, improper or illegal use of your account.

You may cancel your account at any time by clicking on the “report a problem” link at the bottom of the Site

Ex Libris APIs and API Materials

The APIs and API Materials are made available for use and access by Members that are customers of the relevant Ex Libris programs and services for their internal purposes and to other developers that can certify that they will not, on their own or on another party’s behalf, use or access such APIs or API Materials for any commercial purpose, including, without limitation, in connection with the marketing, sale, distribution, development or availability of any commercial third party products or services. Any use or access of the APIs or API Materials for commercial purposes or by or on behalf of third parties that are marketing, developing or distributing commercially available products or services is strictly prohibited without a separate license agreement signed by Ex Libris.

Subject to the foregoing and to the other terms and conditions set forth in the Terms and to compliance with any other rules and restrictions regarding API use published by Ex Libris on the Site (such as, without limitation, API governance thresholds), Ex Libris hereby grants to relevant Members a non-exclusive, royalty free, revocable, non-transferrable license to use the Ex Libris APIs and API Materials solely for the purpose of developing applications which are interoperable with Ex Libris programs and/or services and for facilitating interoperability between Ex Libris programs and/or services with existing third party applications.

In order to access some of the available APIs, whether to an Ex Libris guest sandbox, a customer’s Ex Libris programs and services or otherwise, a User must generate a unique service key on the Site (the “API Key”) which shall be subject to the terms and conditions set forth in these Terms.

You acknowledge that enablement of APIs and API Keys linked to a customer’s Ex Libris programs and services may provide third party programs access to your personal and other data which is stored in your Ex Libris programs and/or services (“Data”). Please be aware that the testing, installation or enablement of APIs may result in the transmission of your Data outside of Ex Libris’ programs and/or services during normal use. Furthermore, third parties may be able to obtain access to your Data through the APIs, which may result in the disclosure, modification or deletion of your data by those third parties. Ex Libris is not responsible for any such transmission, disclosure, modification or deletion of your Data by or through the APIs.

You may not sell, transfer, sublicense or otherwise disclose the API Keys to any third party, except for disclosure to third parties who are providing services to you in compliance with the Terms and subject to your remaining responsible for such third party’s activities and for their compliance with the Terms. You are responsible for maintaining the confidentiality of all API Keys and for any activities that occur using the API Keys. You agree to indemnify and hold Ex Libris harmless for any unauthorized, improper or illegal use of your API Keys.

Customers may find information relating to the usage of the APIs and the performance of the APIs on the Ex Libris API Dashboard. All APIs, related documentation and information available on the Ex Libris Dashboard are provided “as is”. Ex Libris has no obligation to provide support services for APIs or to update the APIs to support the latest programs and/or services of Ex Libris or any third parties.
