Contentstack allows you to delete a taxonomy that you create in your stack.
Note: Unless you are the Owner or Admin of the stack, you cannot delete taxonomies created by other stakeholders.
To delete a taxonomy, log in to your Contentstack account, and perform the following steps:

Warning: Deleting a taxonomy removes its connections to any linked content types. This also increments the entry version because the terms associated with the deleted taxonomy were removed from the entry.

Alternatively, select a taxonomy and click the trash icon at the top-right corner to delete it.

Additional Resource: To recover a deleted term, consult our documentation on restoring deleted taxonomies.
To delete taxonomies via the API, refer to the Delete a Taxonomy API request.
Note: While restoring a taxonomy or term, or when creating or deleting a branch, avoid performing additional delete or restore operations until the ongoing process is complete. This restriction is implemented to prevent conflicts, as multiple entries are modified simultaneously during these processes.
