Authentication V2

Authentication service for SW services using a username and password. It generates a temporary token, valid for two hours, that you can use to connect to SW services.

✓ Before you start
1 Request sandbox credentials through our form. For production, use the username and password of your SW account.
2 Choose your environment. Sandbox credentials don’t work in production, and vice versa.
3 Cache the token and renew it before it expires. Check expires_in before each call; don’t request a new token for every stamping request.
💡 Recommendation: If you need a non-expiring token, you can get an infinite token assigned to your account from the Stamp Manager (Administrador de Timbres).

URLs
