Sandbox environments will contain a copy of these entities:
The following entities are not copied in an environment since they belong to a space:
No, space environments are available via API and inside the web app.
Our SLAs only cover the availability of content within the master environment of a space. Keep in mind that the primary use of sandbox environment is to do internal development and testing, not to be consumed by end users.
The duration of the process depends on the size of your space. A rule of thumb is around 7000 entities per second, which means that it will take just a couple of seconds to copy a master environment with 50000 records. Since the copy process happens server-side, you don't have to worry about running into rate limits or changing the original meta-data associated with the content (create dates, entity IDs).
Space environments can only be accessed by users who have a space admin role (don't mistake that with an organization admin role!). At the moment, users with other roles cannot access space environments. Also, we do not allow to selectively assign space environments to specific users.
We do not provide any functionality for merging the changes back into master on our side. Instead we recommend using the Migration CLI to reapply tested changed from a sandbox environment to master environments.
Yes, you can use CDA/CPA with sandbox environments in the same way you use them with the master environment. If you are using preview links, remember that these are configurable on a space level and not per individual environments.
Yes, webhooks can trigger for all environments. Use the webhook
filters peroperty to control that. See: https://www.contentful.com/developers/docs/concepts/webhooks/#filters
Yes, locales are isolated by environments, which means you can change, add, and remove locales when working within sandbox environments.
