Use FreeClimb in the language of your choice to get up and running quickly. Each SDK section will provide instructions on how to download and set up the SDK. We are working to add more SDKs, so please let us know in the forum if there is a language you are looking for that we do not currently support.

Testing Your Installation

Testing your installation of an SDK can be done by sending yourself an SMS. Instructions for how to do this are included with each SDK. If you are a trial account user, you'll want to add one or more Verified Numbers in your Dashboard (for example, your personal number). During your trial account period, FreeClimb can only contact Verified Numbers.
