⚠️ Notice
This API License Agreement has been replaced by the Rebilly Subscription Agreement effective January 21, 2026.
For all new customers and renewals, the governing agreement is:
https://www.rebilly.com/legal/subscription-agreement
This legacy agreement continues to apply only to customers who accepted it prior to that date.
IMPORTANT: This API License Agreement ("Agreement") is a legally binding contract between you, as Licensee ("You" or "Licensee"), and Rebilly Inc. and applies to your use of Rebilly’s recurring billing software and Rebilly Resources, as defined herein, available through www.rebilly.com (collectively, the "Service"). The Service includes an Application Programming Interface ("API" or "Program"), which is further discussed and defined below. If you do not agree to be bound by the terms and conditions of this Agreement, please do not proceed with the use of our Service or the API. In this Agreement, the terms "you" or "your" mean any person or entity using the Service ("Users"). Unless otherwise stated, the terms "Rebilly," "we" or "our" will collectively refer to Rebilly Inc. acting on behalf of itself and its affiliated companies, including Rebilly SRL, the owner of the Rebilly intellectual property. This Agreement becomes effective as of the date you first access, download or use the API, or click the Acceptance button below ("Effective Date"). This Agreement shall continue until terminated either by us or by you. Even after termination of this Agreement, certain provisions will survive, as discussed herein. This Agreement incorporates the Data Processing Addendum ("DPA"), to the extent applicable, which governs Rebilly’s processing of Licensee Data in connection with the Service. Rebilly’s Website Terms of Use apply solely to use of Rebilly’s marketing website and do not govern the Rebilly platform, APIs, or Services.
YOU ARE ENTERING A LEGALLY BINDING CONTRACT: BY COPYING, DOWNLOADING, OR OTHERWISE USING THE REBILLY API YOU ARE EXPRESSLY AGREEING TO BE BOUND BY ALL TERMS OF THIS AGREEMENT. IF YOU DO NOT AGREE TO ALL OF THE TERMS OF THIS AGREEMENT, YOU ARE NOT AUTHORIZED TO COPY, DOWNLOAD, INSTALL OR OTHERWISE USE THE REBILLY API.
1.1. API License. Subject to the terms and conditions of this Agreement, Rebilly grants to you a non-exclusive, non-transferable, non-sublicense-able, limited license to use the Application Programming Interface ("API License") solely in accordance with the terms of this Agreement. The API License allows you to do only the following:
1.1.1. Access the Rebilly Resources ("Resources") and use the API certificate only in the manner provided by Rebilly; Rebilly Resources may include but are not limited to resources for customers, invoices, payment cards, subscriptions, transactions, block lists, disputes, layouts, plans, authorization options, credentials, and tokens;
1.1.2. Use the API as necessary to conduct your business;
1.1.3. Execute transactions using the Rebilly Service; and
1.1.4. Comply with this Agreement and all applicable laws in connection with your use of the API and Service.
1.2. Any combination of Sections 1.1.1-1.1.4 above shall be deemed "Permitted Use." Permitted Use is subject to all terms set forth in this Agreement. To enable your Permitted Use, Rebilly will provide you with a confidential identification code, Certificate, and User ID that shall permit you to use the API. The User ID will remain the property of Rebilly and may be revoked or terminated by Rebilly immediately if you fail to keep it confidential (for example by sharing it with any third party, other than a Third Party Service Provider), if compromised in any way, or if you use or access the Program or Rebilly Resources in any manner not expressly permitted under this Agreement. A "Third Party Service Provider" shall refer to any third party service provider who is reasonably needed to undertake the Permitted Use and who is subject to all restrictions herein, including confidentiality provisions at least as restrictive as those set forth in Section 7 ("Confidential Information"). “Affiliate” means any entity that directly or indirectly controls, is controlled by, or is under common control with Licensee.
1.3. General License Conditions and Restrictions. You agree that you will neither use the Resources or the Program in any way not expressly permitted under this Agreement, nor use any alternative means such as robots, spiders, scraping or other technology to access, query, or use www.Rebilly.com, or any other website owned or operated by Rebilly or any of its affiliates (the "Rebilly website"), Resources, or Program to obtain any information, other than as provided by Rebilly to you pursuant to this Agreement. You may not distribute, facilitate, enable or allow access or linking to the Rebilly Resources from any location or source other than your website. Following expiration or termination of this Agreement, you shall not use (or facilitate use of) any alternative means such as robots, spiders, scraping or other technology to access, query, or use the Rebilly website, Resources, or Program to obtain any information.
1.4. Restrictions and Conditions on Use. You agree that you shall not use the Program or Resources, or permit same to be used in any manner, whether directly or indirectly, that would (i) permit the disclosure of the Program or Resources, to, or the use of the Program or Resources by, anyone other than your your employees, Affiliates, and Third Party Service Providers, or (ii) enable the Program to be used in any location other than your website (unless Rebilly otherwise has agreed in writing for your use elsewhere). Licensee shall remain responsible for compliance with this Agreement by its Affiliates and Authorized Users.
1.4.1. Specific Prohibitions: Notwithstanding anything to the contrary in this Agreement, you are specifically prohibited from doing any of the following:
1.4.1.1. You shall not sell, transfer, sublicense, or disclose your User ID to any third party (other than Third Party Service Providers); and
1.4.1.2. You shall not modify, decompile or otherwise alter the Program or Resources.
2.1. Resources and IP Ownership. Except as otherwise expressly provided in this Agreement, as between Rebilly and You, Rebilly SRL (or its licensors) retains all right, title and interest in and to all intellectual property rights (including, without limitation, all patent, trademark, copyright, trade dress, trade secret, database and other intellectual property rights) embodied in or associated with the Program, the Rebilly Resources, the Rebilly website, and any and all Rebilly services, technology, documentation, and content created or derived therefrom. Rebilly Inc. is authorized by Rebilly SRL to grant the licenses set forth in this Agreement. This Agreement does not create any implied licenses, and all rights not expressly granted to You are expressly reserved by Rebilly SRL and its licensors. You shall not take any action inconsistent with Rebilly SRL’s ownership of the Program, the Rebilly website, or the Rebilly Resources.
2.2. No Sublicensing. Any license rights granted hereunder are granted exclusively to you and may not be sublicensed, transferred or assigned, except as otherwise provided herein.
2.3. Trademark Ownership. Rebilly owns all of its trademarks and service marks, including its logo ("Rebilly Marks"). While this Agreement remains in effect you are granted a non-exclusive, non-transferable, non-sublicenseable, non-assignable right to display the Rebilly Marks on your website. Rebilly may from time-to-time update or revise its trade dress and, in such event, you agree to immediately remove any non-current Rebilly Marks from your website. Rebilly may also revoke this limited grant at any time and for any reason. If you use the Rebilly Marks your use is at your own risk. Although Rebilly has taken reasonable efforts to ensure its Marks do not infringe upon the rights of others, you agree that you will not seek indemnity from Rebilly in the event of a claim from a third party arising out of your use of the Rebilly Marks. Rebilly makes no representation nor does Rebilly warrant or agree to defend or hold you harmless from any such claim. To the contrary, Rebilly shall not be liable for any costs or damages (including attorneys' fees) associated with claims made against you related to the Rebilly Marks. Because intellectual property law is inherently unpredictable, you expressly agree that your use of the Rebilly Marks is conditioned upon these terms. If you do not agree, do not use the Rebilly Marks.
2.4. Uptime; Rate Limiting. Rebilly does not guarantee uninterrupted availability of the Rebilly website or Rebilly Resources. Availability commitments, maintenance windows, response times, and service credits (if any) are governed exclusively by the applicable Subscription Agreement or service level agreement between the parties. Rebilly reserves the right to limit the rate and usage of its Resources as it deems appropriate and will use commercially reasonable efforts to provide advance notice of material rate-limit changes where practicable.
3.1. Termination. Either party may terminate this Agreement for convenience upon reasonable written notice. Either party may terminate this Agreement immediately for material breach that remains uncured after written notice, or immediately where required by law, security risk, or regulatory obligation.
3.2. Survival. Notwithstanding termination of this Agreement, the following Sections will survive and remain binding: Section 1.3 ("General License Conditions and Restrictions"), Section 1.4 ("Restrictions and Conditions of Use"), Section 2 ("Intellectual Property"), Section 3.2 ("Survival"), Section 6 ("Representations and Warranties"), Section 7 ("Confidential Information"), Section 8.4 ("Limitation of Liability"), Section 9 ("Indemnification"), and Section 10 ("General").
3.3. Effects of Termination. Upon termination of this Agreement, your User ID will be revoked and all licenses granted pursuant to this Agreement will immediately terminate unless such licenses are expressly stated as surviving.
4.1. Rebilly reserves the right to change the method of access to the Program and/or Resources at any time to ensure the safety and security of its environment. In the event of degradation or instability of Rebilly’s systems or in an emergency, Rebilly may, to the extent reasonably necessary, temporarily suspend Licensee’s access in order to protect the operational stability and security of the Rebilly system. Rebilly will use commercially reasonable efforts to notify Licensee of any such suspension where practicable.
5.1 The Service may provide you with access to, be integrated with, or contain links or references to, products, services, data, information, websites or other materials which are provided or operated by third parties (collectively, "Third Party Products"). In such cases, Rebilly only provides API services for connecting these Third Party Products to the Service provided by Rebilly not the Third Party Product itself. “Rebilly Website” means Rebilly’s public marketing website located at www.rebilly.com and excludes the API, Hosted Payment Pages, Admin UI, and operational platform components.
5.2 Any exchange of data between you and any third-party provider of a Third Party Product, is solely between you and the applicable third-party provider. By integrating with a Third Party Product, you acknowledge and agree that: (i) Licensee Data may be shared with the third party provider; and (ii) Rebilly shall not be held liable to and shall not accept any liability, obligation or responsibility whatsoever for any loss or damage in connection with the data we provide to such third parties. Rebilly only exchanges Licensee Data with third-party providers that are expressly configured or authorized by Licensee (including payment gateways). Rebilly does not disclose or sell Licensee transaction data to unrelated third parties for transaction processing purposes.
5.3 YOU ACKNOWLEDGE AND AGREE THAT YOUR ACCESS TO THE RESOURCES AND YOUR USE OF THE API IS PROVIDED HEREUNDER ON AN "AS IS" BASIS WITHOUT WARRANTY OF ANY KIND. EXCEPT AS EXPRESSLY PROVIDED IN THIS AGREEMENT, REBILLY DISCLAIMS ALL WARRANTIES AND CONDITIONS, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OR TERMS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. REBILLY DOES NOT REPRESENT OR WARRANT THAT THE REBILLY WEBSITE SHALL OPERATE SECURELY OR WITHOUT INTERRUPTION. You acknowledge that you have not entered into this Agreement in reliance upon any warranty or representation.

7.1. Confidential Information Defined. Rebilly may from time-to-time disclose to you information that is marked "Confidential" that contains proprietary information for your sole use in relation to this Agreement. If disclosed orally, Rebilly may identify certain information as "Confidential." All such information shall be considered "Confidential Information." In addition, the terms of this Agreement, Rebilly Resources, the Program, and your User ID shall be deemed Confidential Information regardless of whether marked or designated "Confidential."
7.2. Your Obligations. You agree to keep and hold Rebilly's Confidential Information in confidence and not disclose such Confidential Information to third parties nor use Rebilly's Confidential Information for any purpose other than as required to perform under this Agreement.

In such instances, you agree to use reasonable efforts to avoid disclosure of Confidential Information and, if necessary, use reasonable efforts to obtain confidential treatment or protection by order of any disclosed Confidential Information (e.g. via protective order). Notwithstanding any contrary provision in Section 10.6 ("Notice"), notification to Rebilly under this Section 7.2 must be provided by personal delivery on a same day or overnight basis, overnight courier, confirmed facsimile, or confirmed email. Your obligations under this Section shall survive the termination of this Agreement for a period of five (5) years.
7.3. Rebilly Obligations. Rebilly shall protect Licensee’s Confidential Information with at least the same degree of care it uses to protect its own confidential information, and in no event less than reasonable care, and shall notify Licensee without undue delay of any unauthorized access or disclosure of such Confidential Information.
