Save a QR code design, to keep codes consistent across locations. You'll need a name, a location (store_id) and the design type (template_type); the design options are optional. Each design counts towards the location's plan allowance for QR codes: when the plan doesn't include QR codes or the allowance is used up, the call returns 402. Returns the template with its id.

Prerequisites: a bearer token for the account, and a location id (store_id).

Authentication: Account token. store_id must be inside your own account tree (otherwise 422). QR designs belong to the account that created them and every QR endpoint matches on that account exactly, so a Partner token sees nothing.

Rate limit: none.
