API version 2.2 deprecation
On April 15th, 2023, we will be deprecating version 2.2 of the Neon CRM API v2. After this date, requests to API v2 that include the header NEON-API-VERSION: 2.2 will receive a HTTP 410 error, indicating that the API version is no longer valid.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 2.2 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 already default to use the most recent version of the API.
This change will not affect version 1 of the Neon CRM API, and this legacy API will continue to be supported.
