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.
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.
