Rillet Integration
Integrating Rillet with Sphere enables a.) seamless transaction data import and b.) live tax calculation within Rillet invoices.
This guide provides step-by-step instructions on generating an API key in Rillet, linking it to Sphere for a secure integration.
It also covers configuring the Sphere Tax API within Rillet to ensure accurate tax calculations.
Part 1: Configure Data Synchronization from Rillet to Sphere
In your Sphere account, select the Rillet tile and click the “Connect” button.

A modal will appear — click the “Get Started” button to proceed.

Go to https://app.rillet.io/settings/api-access to access your Rillet API settings. From there, you can generate a new API key. Make sure to save the key securely, as you'll need it in later steps.

Go back to the Sphere app, paste the Rillet API key, and click Next.

You’re all set! If the connection is successful, data will begin importing, and after some time, your products will appear in Sphere.

Part 2: Configure Sphere Tax API Key for Tax Calculation
In Sphere, click on "Create a new API Key" to generate the Sphere Tax API Key. Be sure to save the newly generated key, as it cannot be viewed again later. You’ll need to provide this key to the Rillet team manually, as their app currently doesn’t support entering it directly.
