Webhooks Updates {#webhooks-validations-decommission}
=====================================================

We have added new validations for version 1 of webhooks:

* Only alpha-numeric data and spaces are allowed in the name field of newly created or updated subscriptions. Existing version 1 subscriptions are not affected unless they are updated.
* Most webhooks fields for newly created or modified subscriptions will not accept HTML tags. Existing version 1 subscriptions are not affected unless they are updated.
* The securityType field in `Create` and `Patch` requests accepts only one of the following values: `key`, `oAuth`, or` oAuth_JWT`

Version 1 will be decommissioned in April 2026. We recommend that you begin using [webhooks version 2](https://developer.cybersource.com/api-reference-assets/index.md#webhooks "").
