## AI overview

This tutorial explains how to configure device-specific custom data during initial ESP32 provisioning using the unified provisioning infrastructure in ESP-IDF and ESP-Jumpstart. It covers the provisioning communication stack, custom API endpoints, and a callback-based implementation for configuring values such as a user-friendly device name.

## Source excerpt

One of the common requirements I have seen is, during the initial device provisioning, configuring some device specific custom data on the device. This could be something as easy as assigning a user-friendly name to the device, or something like initialising the Alexa credentials on the device. The unified provisioning infrastructure within the ESP-IDF/ESP-Jumpstart allows for this mechanism with ease.
