Get the account's email templates, to pick one for a campaign. Each entry's value is the email_template_id for POST /api/v1/campaign/template/email/update. Returns one entry per template, sorted by name: your account's templates, the shared (global) templates and, when you send store_id, that location's templates. Not paginated.

Prerequisites: a bearer token. Optional: a location id (store_id) to include that location's templates.

Authentication: Account token. Lists the templates of the account of the user behind the token, plus the shared templates. store_id must be inside your own account tree; otherwise 422.

Rate limit: none.
