This Developer Addendum (“Developer Addendum”) applies to all Customers that, through their Developers, utilize our Developer Tools to create or distribute Integrations. This Developer Addendum supplements and comprises part of the Agreement. 


For purposes of this Developer Addendum, the “Agreement” refers to either the Terms of Service or the Main Services Agreement between you and Mural  (as applicable to you). Some capitalized terms are defined in this Section 1, and others are defined contextually elsewhere in this Developer Addendum. Any capitalized terms that are not defined in this Developer Addendum have the meanings assigned to such terms in the Agreement.

Developer Tools” means any software (including APIs, SDKs, scripts, and libraries) related to Private Apps, Unlisted Apps, or Public Apps, and any related Documentation, tools and Materials,  that we make available to Customers and their Developers through our Sites, and are considered part of the Services under the Agreement.

Developers” are your Authorized Users who use our Developer Tools.

Private App” means an Integration that is visible to and usable only by the Developer who created it.

Public App” means an Integration that you choose to distribute and make available for use by all Mural customers and collaborators in connection with the Services.

Unlisted App” means an Integration that a Developer chooses to share using a private link.


2.1 License and Use. The Developer Tools are part of the Services and subject to all license and use provisions and restrictions in the Agreement. For the avoidance of doubt, Mural grants you and your Developers a limited, non-exclusive, non-sublicensable, non-transferable right and license to access and use the Developer Tools as detailed in our Documentation and this Developer Addendum. We may place limits on access to the Developer Tools, including limiting the number of network calls, file size or requests you may make on the platform. You agree to follow the registration or credentialing requirements (if any) established by us for access to the Developer Tools. All Developer Tools access keys or credentials are Mural Confidential Information. Mural reserves the right to make updates to our Developer Tools, including potential break updates. Developers are responsible for updating their Integration(s) accordingly. 

2.2 Your Integrations. The scope of your rights to your Integrations created using our Developer Tools is a matter between you and your Developers. Subject to our rights (or those of our licensors) in and to the Services, including the Developer Tools, Mural claims no ownership in your Integrations. By accessing and using the Developer Tools, you grant us a license to host, use, transmit, display, perform, copy, distribute, and modify your Integrations to enable us to provide the Services. (We may need to modify your Integrations to conform to technical requirements for viewing on your computer or mobile device.) This above license is non-exclusive, royalty-free, sublicensable (as expressly provided for below), revocable and worldwide. Mural may only sublicense to third parties with whom Mural has a contractual relationship and only for the limited purpose of providing the Services. 

2.3 Third Party Components. The Developer Tools may be provided in conjunction with other components, including third party software components that are provided by their authors under separate license terms. Such third party components are considered “Third Party Services” under the Agreement.

2.4 Listing Information. You represent and warrant that your Integration listing information is truthful, accurate and complete. You will maintain updated and accurate listing information for your Integration. 

2.5 Support & Maintenance.  You are solely responsible for all support, operation and maintenance of your Integration, including any necessary user agreements, privacy notices, data processing agreements, and other terms and conditions that pertain to your Integration. Failure to provide and maintain adequate support for your Integration may result in low ratings, less prominent placement, removal from the Services, and suspension or termination of access to and use of the Developer Tools. THE MURAL SLA (IF APPLICABLE TO YOU) DOES NOT EXTEND TO THE DEVELOPER TOOLS OR YOUR INTEGRATIONS. The parties will redirect any customer support inquiries related to the other’s products or services, and will cooperate in good faith to troubleshoot technical issues related to the Developer Tools.

2.6 Acknowledgement. You acknowledge and agree that Mural may be independently engaging in Product Research or developing Integrations, content, software, or other products or services that may be similar to your Integrations. Nothing in the Agreement will be construed as restricting or preventing Mural from such Product Research or development, or from fully exploiting your Integrations as contemplated in this Developer Addendum. Whether your Integration will be a Private App, an Unlisted App, or a Public App, is your decision and your responsibility; once an app is distributed as an Unlisted App or Public App, it cannot be made a Private App.  We reserve the right (but undertake no obligation) to, in our sole discretion and without notice or liability, take down or delete any Integrations, and to suspend or terminate access to and use of the Developer Tools or Services by any person, for breach of our Agreement or Documentation. You will provide reasonable cooperation in any investigation or action regarding suspected or alleged violations of our Agreement or Documentation related to your Integrations. 


We do not have an obligation to monitor, and will not monitor, your Private Apps or Unlisted Apps for compliance with our Agreement or Documentation. We do not have, and do not undertake, any obligation to prescreen, monitor, edit, or remove any Private Apps or Unlisted Apps. Distribution of a Private App or Unlisted App through our Services does not constitute a Mural endorsement or warranty of you or such Integrations. 


4.1 Prior Approval Required. Your Public App must be approved by Mural prior to public distribution. Mural may approve or decline your Public App for public distribution in our sole discretion.

4.2 Branding. You will not make any statements that imply a Mural endorsement, certification, affiliation, or partnership with you without our prior express written consent. You will adhere to our brand guidelines and trademark guidelines, as we may update from time to time, and will respect our trademarks, service marks, brand and brand assets. Any and all goodwill that arises from your use of our trademarks and service marks shall inure solely to our benefit.

4.3 Publicity. You grant us a non-exclusive, limited, perpetual license to use your trademarks, service marks, logos or trade names, as well as any descriptive materials you provide about your Public App, for purposes of supporting, marketing and promoting your Public App, the Developer Tools and the Services, whether by Mural directly or through our third party partners and vendors. We will adhere to any trademark or content guidelines that you provide to us, and any goodwill that arises from our use of your marks shall inure solely to your benefit. 

4.4 Security Reviews & Audits. You grant permission to Mural and its designated personnel or authorized third party partners or vendors to perform, at times and dates selected by Mural, one or more security reviews on your Public Apps for purposes of determining and establishing safety and fitness of your Public Apps for distribution. All information and materials associated with such security reviews are considered Mural Confidential Information. You may request that Mural stop the security reviews of your Public Apps at any time, however, such a request may result in a 'Failed' review and your Public App being denied approval for distribution or taken down. You have sole responsibility for adequate protection and backup of your data and systems used in connection with these reviews, and you agree not to make a claim against Mural for any lost data, re-run time, inaccurate output, work delays or lost profits resulting from these reviews. Mural further reserves the right to audit your Public Apps at any time to ensure they do not violate our Agreement or Documentation. You will provide reasonable cooperation and assistance to us in our security reviews and audits of your Public Apps, including by providing requested documentation in a timely manner.

4.5 Termination and Material Changes.  You will provide us with at least ninety (90) days prior written notice of any termination or material change in function, distribution or support for your Public App, or termination of the Agreement or this Developer Addendum. Mural reserves the right to immediately terminate this Developer Addendum in the event of a material breach of our Agreement or this Developer Addendum, including a failed security review or audit or repeated material complaints from end users or customers. Upon notice of termination, the parties will wind down all activities related to your Public App, remove your Public App from public distribution, and cease distribution of any marketing or other materials related to your Public App. The wind down period will expire ninety (90) days after notice of termination.
