API version 2.5 deprecation

February 28, 2024

On March 16, 2024, we will be deprecating Neon CRM API v2.5. After this date, requests to API v2 that include the header NEON-API-VERSION: 2.5 will receive a HTTP 410 error, indicating that the API version is no longer valid.

Learn more about versioning in API v2.

If your application currently specifies version 2.5 in your API request headers, we recommend updating to the most recent version of the API v2. API requests that do not include the NEON-API-VERSION header will default to use the most recent version.

This change will not affect Neon CRM API v1, and this legacy API is still currently supported.

API v2.8 will be released on March 16, 2024, and release notes will be available by March 16. API v2.6 and v2.7 will continue to be supported.
