Hello ThomasH5307,
Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
While there is no ETA at this time, we are in the process of developing endpoints for the V3 API related to the new Events tool that was recently released. While our legacy V2 API has Event endpoints**, they are only compatible with the legacy Events tool, which will soon be retired. However, it is possible that there could be a period of time in between where there are no event endpoints available via either version of the API.
On April 1st, 2024, our legacy event tool will no longer be available. Any existing legacy events will become "read-only" and you will not be able to create new legacy events or the copy functionality for existing legacy events.
Effective July 1st, 2024, the legacy events tool will be retired from our product completely. At that time, you will not be able to create, copy, migrate to 2.0, or view prior legacy events.

You can view our available V3 endpoints via the Constant Contact Developer Portal:

**While there are Event endpoints available via our legacy V2 API, it is not advised that you develop a new integration for this purpose, as there will be a point in the near future where our legacy V2 API (as well as the legacy events tool) will begin deprecation. Due to this, while we will continue to deploy critical bug fixes at this time, we will not be doing any more development for V2 or its endpoints (it is not currently up to date regarding more recent campaign types and features), and strongly recommend all new applications be created using our V3 API, which is the current version.
Please have a look and let us know if you have any other questions!
