Slack API Terms of Service Agreement
Acceptance of Terms
If you are entering into this API TOS on behalf of a company or other legal entity, you represent that you have the authority to bind such entity to this API TOS. In that case, the terms “you” or “your” shall also refer to such entity. If you do not have such authority, or if you do not agree with this API TOS, you may not use the Slack API. You acknowledge that this API TOS is a contract between you and Slack, even though it is electronic and is not physically signed by you and Slack, and it governs your use of the Slack API.
API Key Definitions
- Application – Any software application, website, or product you create or service you offer using the Slack API (defined below).
- API Documentation – The documentation, data and information that Slack provides regarding the use of the Slack API through the Developer Site.
- Data – means any data and content uploaded, posted, transmitted or otherwise made available by users via the Services, including messages, files, comments, profile information and anything else entered or uploaded into the Service by a user of the Service.
- Developer Site – Slack’s Developer site found at https://api.slack.com/
- Slack API or “our API” – The publicly available Slack Application Programming Interface (“API”) as well as the related API Documentation.

The “Service” does not include Data or any software application or service that is provided by you or a third party (including Applications), whether or not Slack designates them as “official integrations”.
As long as you follow this API TOS, Slack grants you a limited, non-exclusive, non-assignable, non-transferable license to use the APIs to develop, test, and support any software application, website, or product, and to integrate the Slack APIs with your Application. Your license is subject to the limitations set forth in Section 4.2 through 4.11 and Section 9 below, and you agree that violation of Section 4 will automatically terminate your license to use the Slack APIs.
Use of APIs and Slack Data
The following identifies limitations on use related to the Slack API:
- Reliance on API. Slack is still evolving, and we need the flexibility to occasionally make changes to our APIs, including backwards incompatible ones. We will try to give notice of these changes, but you should follow the @slackapi Twitter account for updates. Also, parts of our API are undocumented, including certain methods, events, and properties. Given that these undocumented aspects of our API may change at any time, you should not rely on these behaviors.
- Applicable laws or agreements. You may not use the Slack API in violation of any law or regulation, or rights of any person, including but not limited to intellectual property rights, rights of privacy, or rights of personality, or in any manner inconsistent with this API TOS or Slack’s other agreements to which you are subject.
- Scope of acceptable use. You may not use the Slack API or any other technology in a manner that accesses or uses any information beyond what Slack allows under this API TOS or the Documentation; that changes the Slack Service; that breaks or circumvents any of Slack’s technical, administrative, process or security measures; that disrupts or degrades the performance of the Slack Service or the Slack API; or that tests the vulnerability of Slack’s systems or networks.
- Malware. You may not transmit any viruses or other computer programming that may damage, detrimentally interfere with, surreptitiously intercept, or expropriate any system or data.
- Reverse engineering. You may not attempt to reverse engineer or otherwise derive source code, trade secrets, or know-how in the Slack API or portion thereof;
- Functionality. You may not use the Slack API to replicate or compete with core products or services offered by Slack. You acknowledge and agree that Slack has or may in the future offer products or services that are similar to your Application, and nothing will prevent Slack from doing so;
- Commercial Use. You may charge for your Application. However, you may not sell, rent, lease, sublicense, redistribute, or syndicate access to the Slack API.
Advertising. You may place advertisements on and around your Application. However, you may not:
- Place any advertisements within Slack Service channels, and your advertisements may not resemble or be reasonably likely to confuse users as being a Slack Service message;
- Use Data or any content from Slack in any advertisements or for purposes of targeting advertisements, in your Application or elsewhere; or
- Use contact information obtained from Slack (including email addresses) to contact Slack users outside of Slack without their express permission.
- Rate Limits. You will not attempt to exceed or circumvent limitations on access, calls and use of Slack API, or otherwise use the Slack API in a manner that exceeds reasonable request volume, constitutes excessive or abusive usage, or otherwise fails to comply or is inconsistent with any part of this API TOS or the Documentation. See https://api.slack.com/docs/rate-limits.
- Use for promotion of gambling or adult content. You may not use the Slack APIs in any Application that includes adult content, promotes gambling, involves the sale of tobacco or alcohol to persons under 21 years of age, or otherwise violates any applicable law or regulation.
- Distribution of your application. You may not distribute or allow access to the Slack APIs to anyone other than, if applicable, the company on whose behalf you entered into this API TOS. Anyone who wants to access our APIs must agree to be bound by this API TOS.
- Use of Slack Brand or Marks. You must not use the Slack Brand in a way that suggests your service is endorsed by, sponsored by, or associated with Slack, and you must abide by Slack’s Brand Guidelines available at https://slack.com/brand-guidelines.
Storage of Data
- Caching Data. Where Data is cached, you should refresh the cache at least every 24 hours.
- Secure Storage Measures. All Data should be stored and served using strong encryption.
- Delete at User Request. You must delete all Data you have collected from a Slack user upon request by that user, and when the Slack user deauthorizes your Application or closes his or her account with you. Similarly, when a team stops using your Application, you should delete all Data obtained from that team. The restrictions of this Section do not apply to Data that Slack users also provide directly to you and that is separately entered or uploaded to you by the user of your Application.
- Deletion at Termination. If we terminate your use of the Slack APIs for any reason, then you must permanently delete all Data and any other information that you stored pursuant to your use of the Slack APIs, except when doing so would cause you to violate any law or obligation imposed by a governmental authority. This provision does not require a Slack user to delete Data stored in Slack if the Slack user is prohibited from accessing the Slack API.
- No Other Storing. You may not copy or store any Data or capture or store any information expressed by the Data (such as hashed or transferred data), except to the extent permitted by this API TOS.
- Protections. The network, operating system and software of your web servers, databases, and computer systems (collectively, “Your Systems”) must be properly configured to securely operate your Application and store Data. Your Application must use reasonable security measures to protect your users’ information. You must not architect or select Your Systems in a manner to avoid the foregoing obligation.
- Reporting. You must promptly report any security deficiencies in, or intrusions to, your Systems to Slack in writing via email to email@example.com or subsequent contact information posted on the Developer Site. This includes any unauthorized access, use, disclosure or destruction of Data. You will work with Slack to immediately correct any security deficiency, and will immediately disconnect any intrusions or intruder. In the event of any security deficiency or intrusion involving the Application, Slack APIs or Data, you will make no public statements regarding such deficiencies or intrusions (e.g., press, blogs, social media, bulletin boards, etc.) without prior written and express permission from Slack in each instance.
Government Access. You will not knowingly:
- Allow or assist any government entities, law enforcement, or other organizations to conduct surveillance or obtain data using your access to the Slack API in order to avoid serving legal process directly on Slack. Any such use by you for law enforcement purposes is a breach of this API TOS.
- Display, distribute or otherwise make available Data or any Application to any person or entity that you reasonably believe will use Data to violate the Universal Declaration of Human Rights (located at http://www.un.org/en/documents/udhr/), including without limitation Articles 12, 18, or 19. Any law enforcement personnel seeking information about Slack users will be referred to Slack’s User Data Request Policy, located at https://slack.com/user-data-request-policy. You will not conduct and your Application will not provide analyses or research that isolates a small group of individuals or any single individual for any unlawful or discriminatory purposes. Exemptions to these restrictions may be requested for exigent circumstances and are subject to prior written approval from Slack.
