Download the managed-account import template

Downloads the sample CSV that POST /v1/accounts/imports expects: the required headers plus one example row, separated by semicolons and written with a UTF-8 byte order mark so that Excel opens it with the accents intact — the same conventions as GET /v1/templates/customer-import.

• The example row is deliberately not importable: its tax id has a valid shape and an impossible check digit, so it is rejected instead of silently provisioning an account. Replace it with your own rows.
• customers_file: the optional second file of that import is not a new format; it is the customer import template, unchanged. Download it from GET /v1/templates/customer-import.
• Scope: the file is the same for every credential and does not depend on any account or on any NIF.
