Esper, an API-based platform, provides tools to automate device deployments while ensuring secure management. The Esper Dev Tools allow developers to fully control device deployments, making them more efficient and seamless. By using APIs such as whitelisting system apps on devices, Esper enables businesses to automate tasks like enabling the Calculator app on mobile inventory tablets, which was a critical part of a field worker use case for an inventory management company. The company used Python and the Esper SDK for Python to communicate with Esper APIs, mapping their workflow to specific API actions such as organizing API configuration, getting devices in a group, checking if an app is whitelisted, sending device commands to whitelist an app, and wiring up the application. This example demonstrates how Esper can be used to automate device deployments across various use cases, including installing or uninstalling apps, disabling features, enabling new user features, etc.
