Is there any ability to perform administrative tasks via the API?

Due to the lack of JIT or SCIM provisioning in the current SAML integration, we'd like to be able to automate provisioning ourselves by either a webhook (triggered by a new team member added) or poll team members via the API for new members added (and then use the Okta API to automatically assign the SAML application to the new team member) and also automatically remove team members if their Okta account is deactivated. I know JIT provisioning is on the road map for Pinpoint, but it still wouldn't solve the deprovisioning piece, so I am wondering if this is something we can do via webhooks or the API.
