There are no shared or public sandbox credentials: every developer registers and receives their own. This is the step before any of the four integration paths.

## How to get them

1. Complete the developer registration at https://tilopay.com/en/developers/registro
2. Tilopay enables a test account and issues that merchant's credentials.
3. With those credentials you obtain the API token (/en/developers/api/autenticacion) or the SDK token.

## Test and production

There is no separate sandbox host: test mode is switched from the merchant account. See /en/developers/entornos
