Sandbox Application

The Keap API enables third-party applications to communicate with Keap and process incoming data for a wide variety of uses. Empowering developers to test and effectively leverage our API Infusionsoft offers sandbox applications and Vendor API Keys to developers.

Sandbox Application

Keap sandbox accounts are typically used by developers providing on-going maintenance and services to their app (integration, add-on, plug-in, etc.) or for initial development. Some of the functionality of the sandbox applications is limited. Periodically we disable sandbox applications that have been inactive for long periods of time. Before taking action, we will notify the owner and provide a two week grace period. During this time, the owner can fill out a form to keep their sandbox application.


  • User License: 3
  • Contact Limit: 250
  • Emails: 100/month

Since these sandbox applications are for development and testing purposes we are able to offer these sandbox applications at *no charge. We do collect credit card information to allow the opportunity to test fax functionality. The only time a charge would be incurred to the credit card on file would be for the use of facsimile services. The fee for fax is $0.15/fax.

*No charge for the monthly service. There may be overage or usage rates that apply for facsimiles that are sent.
