Reads the order templates on your supplier account live from the supplier, so you can choose which ones to save into Zuper with Create Order Template; order_template_imported is true for templates already saved for this provider. SRS returns the templates on the provider's customer account (only the name, description, ID and product count) and responds 404 when the account has none. ABC Supply combines templates from every Bill-To account the connection can see, adds the branch each one was created against, and caches the combined list for up to 12 hours (updating the supplier provider refreshes it). QXO returns templates across all of your accounts, most recently changed first, with the account and job number, and caps limit at 100. ABC Supply and QXO require at least one saved branch for this provider (otherwise 400), and the supplier provider must be CONNECTED (otherwise 403).
