Developer sandboxes

Developer sandboxes are Enterprise Grid environments that can be used to build against all of Slack's features both safely and securely, and without an additional cost. The ability to provision sandboxes is a benefit offered by the Slack Developer Program.

Sandbox statuses

A sandbox can have one of the following statuses:

  • Active: Active sandboxes have a default lifespan of six months. As long as you are still eligible to provision sandboxes, you can extend the lifespan of the active sandbox to another six months, every six months.
  • Archived: Once a sandbox reaches the end of its lifespan, it will be automatically archived. Once archived, all users (including you as the admin and owner of the sandbox) will no longer be able to access it.
    • You will receive an email reminding you that your sandbox will be archived 30 days before the sandbox reaches the end of its lifespan.
    • All data will be retained for a three month grace period after the sandbox is archived, except for messages and files based on the limits below. Workflows cannot be executed once the sandbox is archived, including scheduled and webhook workflows.
    • During the grace period, you can choose to unarchive the sandbox; however, the rest of the users in the sandbox must be reactivated via the sandbox Enterprise Management panel.
    • If you lose your eligibility, your sandboxes will be automatically archived within 30 days. If you regain eligibility, you can extend the lifespan of the sandbox.
    • After the grace period, the sandbox will be automatically deleted.
  • Deleted: Once you delete a sandbox, all data including messages, files, workflows, and users will be irretrievable.

What is a developer sandbox?

Who can create a developer sandbox?

Any developer enrolled in the Slack Developer Program can provision or delete a developer sandbox. However, in order to provision a sandbox, you must either be on a Paid plan already, or you must provide a valid payment method for the account.

Are developer sandboxes available to developers without a paid plan? Why is a payment method required for provisioning?

How do Enterprise sandboxes work?

If you belong to an Enterprise organization and your Org Admin has enabled Allow developer sandboxes > Require approval for sandbox provisioning within your organization's settings, you'll need to make a request before you can provision a sandbox.

The steps for provisioning a sandbox will remain much the same, except that you can enter an optional reason for your request. After you click Request Access, your request will be submitted to your Org Admin, who will receive a Slackbot notification.

Your Org Admin will then review your request and, if approved, you'll receive a Slackbot notification that you can go ahead and provision your sandbox. If they deny your request or they have disabled sandbox provisioning for your organization, you'll see the relevant message displayed on both your Dashboard and Sandboxes pages.

Your Org Admin also has the ability to manage the sandbox you createβ€”they can choose to archive it, extend its archive date, or delete it. You'll receive Slackbot notifications when any of these actions are taken.

What features and limitations are applicable to developer sandboxes?
