Autenticação

Obter Token de Acesso

Obtém um token de acesso (JWT) via OAuth 2.0 Client Credentials. As credenciais api_key e api_secret devem ser enviadas no header Authorization: Basic, com o valor em base64 da string api_key:api_secret.

As credenciais são gerenciadas pelo Internet Banking da Conta Simples.

Importante:

O token expira em 1 hora (expires_in: 3600).
Renove o token antes da expiração para evitar interrupções.
Use Content-Type: application/x-www-form-urlencoded no body (apenas grant_type=client_credentials).

  -H "Content-Type: application/x-www-form-urlencoded" \
  -H "Authorization: Basic YOUR_CREDENTIALS" \
  --data-urlencode grant_type=client_credentials
