Disconnecting Airtable integration from miniExtensions will break all your extensions (stop them from working) but will not delete any of your existing extensions. To ensure a seamless transition to integrating with the correct Airtable account, please verify that the new Airtable account has the necessary permissions and access to the bases that you are working on in miniExtensions.
Provided that the new account has the appropriate permissions, this process should only take around a minute, during which your extensions would become unavailable to your end users.
How to "reconnect" the integrated Airtable account or change it
Go to the settings page and select the correct workspace on the left.
Find the Danger Zone section at the bottom.
Click on Disconnect Airtable account.
To remove the integration, you need to confirm in the dialog box.
You will then be redirected to the dashboard. Select the correct workspace on the left and click Connect to Airtable. Make sure that the correct Airtable account is currently logged in in the same web browser as miniExtensions.
Once the connection has been made, verify that there are no errors shown on the miniExtensions dashboard and that your extensions are working. If you forgot to add a base during reconnection, you can add it back in as explained here.
You can also reconnect to Airtable from the workspace settings page, through the Danger Zone section at the bottom.
