API v1 Reference


Limitations of Use

We set and enforce limits on your use of the APIs (e.g. limiting the number of API requests that you may make or the number of users you may serve), at our sole discretion.

The current limitation in place is a quota for the number of concurrent server process threads a given customer may use. We do not currently enforce any quotas on total amount of bandwidth or number of API requests allowed in a given time period.

Please do not attempt to circumvent limitations documented with each API. These limitations are not intended to be punitive and exist to ensure all API users enjoy the same level of quality of service.


Neon CRM has had 99.95% uptime since 2004. We will do everything in our power to ensure our system is always up and running. Our current uptime and related messages are always available on our status page.


If you discover an issue with an API method, please submit a ticket to our support team. A support agent will investigate and follow up with you. Some issues may need to be resolved as part of a scheduled development cycle. The Neon CRM Product and Engineering teams fix bugs and launch new features within monthly sprints, the content of which are planned months in advance. API issues will be prioritized and scheduled accordingly.

We will support and test issues with API methods, but we cannot be responsible for issues related to code hosted on third-party servers (specifically, that which is not written by our team).

Change Management Policies

Neon CRM is constantly being improved, and we will continue to develop API capabilities. We reserve the right to create new API methods, modify the specifications for existing API methods, and deprecate (remove) existing API methods. We strive to keep our API community informed about these updates, and will attempt to inform users of changes as early as possible.

  • New API methods may be announced at any time prior to implementation.
  • Deprecation of API methods will be announced no later than 4 weeks prior to implementation.

Information about changes will be posted to our Developer Center updates page.

Communication with Neon CRM

We may send you certain communications in connection with your use of the APIs. Please ensure that Neon CRM has your current email address for these communications. You may unsubscribe at any time through a link in the email.


If you provide feedback or suggestions about our APIs, then we (and those we allow) may use such information without obligation to you.
