PaidMembershipsPro REST 403 error

I need to use PaidMembershipsPro API to programmatically change a membership of a user.

For my Admin user I created Application Password, then I created base64 from auth data:
const token = Buffer.from(${process.env.WP_USERNAME}:${process.env.WP_APP_PASSWORD}).toString( 'base64');

Set Basic Authorization:
axios.defaults.headers.common['Authorization'] = Basic ${token};

But any /pmpro/v1 route, I’m trying to trigger always returns me the error:

data: {
   status: 'error',
   error: 'Restricted',
   error_description: 'Sorry, you are not allowed to access REST API.'
}

My user has all pmpro capabilities.
