# Account Provisioning API: Account State Operations

The Twilio SendGrid Account Provisioning API provides a platform for Twilio SendGrid resellers to manage their customers. This API is for companies that have a formal reseller partnership with Twilio SendGrid.

You can access Twilio SendGrid sub-account functionality without becoming a reseller. If you require sub-account functionality, see the Twilio SendGrid Subusers feature, which is available with [Pro and Premier plans](https://sendgrid.com/pricing/).

The Account Provisioning API account state operations allow you to update and retrieve the state of your customer accounts. Accounts can be in one of five states: `activated`, `deactivated`, `suspended`, `banned`, and `indeterminate`.
