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
Prerequisite: Note: Rillet authenticates API requests using API keys. To get started, reach out to the Rillet team to enable access. Once enabled, you can create and manage your API keys from the Organization Settings page.
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.

Tax Calculation in Rillet
Ensure all your 'Subscribed Regions' in Sphere have 'Tax Calculations' settings switched to Yes (see video here on how to ensure this is done).

You can go ahead and create an invoice in Rillet for that region. After saving your changes, taxes will be added to the invoice by Sphere through an asynchronous process. This might take some time, so they may not appear immediately.
