# Conta Azul New client\_id format for new applications

Markdown version of <https://harbyn.com/changes/contaazul/2026-10-01-novo-formato-de-client-id-para-novas-aplicacoes>.

Behavior change - Conta Azul. low severity. Announced.

New applications created in the Conta Azul Developer Portal now receive a 48-character client\_id in a different format. Existing applications keep their credentials and need no new authorization. Integrations that treat client\_id and client\_secret as opaque values are unaffected; code that validates their format or length may reject the new values.
