ADXL345 on I2c protocol

Hi! I need help with my ADXL345
Saw a few codes for I2c Interface but none of them are of much help
On a I2c Scanner programme, I can sense my ADXL sensor, I just can’t read the value
Can’t find the correct API for the ADXL.h lib
Can anyone help me to read these value (x, y, z) ?

API? Are you sure you're on the right forum?

Adafruit's tutorial shows you how to hook it up to I2C
