# Toggling marketing consent

This endpoint is used for toggling the marketing permission for an email. The marketing permission for an email is normally gathered [via the customer tagging](/techdocs/implementing-nosto/implement-on-your-website/manual-implementation/adding-the-customer-information.md).

This endpoint is only intended for use when the consent needs to be programmatically managed and should be a considered an advanced use case.

### Token
