Besides the production environment, KeyToCheck offers a sandbox environment.

The sandbox is the exact copy of our production environment and it benefits from production updates synchronously. The only difference being that the sandbox is completely free. Thus, we highly recommend that you take advantage of this environment to develop your integration without the hassle to impact your production account.


The sandbox environment can be accessed freely and is completly free !
