# Sequence Integration

Integrating Sequence with Sphere enables seamless transaction data import and live tax calculation within Sequence. 

This guide provides step-by-step instructions on generating an API key in Sequence, linking it to Sphere for a secure integration.

It also covers configuring the Sphere Tax API within Sequence to ensure accurate tax calculations.\
\
**Note:** If you are attempting to connect to a Sequence sandbox, you will need to use a corresponding Sphere test organization.

### Part 1: Configure Data Synchronization from Nue.io to Sphere

1. In the Sphere account, click on the Connect button on the Sequence tile.
