What it takes to connect it to your AI chat with Hypamoon, with sources." url: https://hypamoon.com/connect-to/sovos --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Sovos Payments and billing # Connect Sovos to Hypamoon Possible, with help from Sovos. The API is documented, but you cannot just create a key: access goes through Sovos first. Possible ## The check Three questions about the API of Sovos, answered from its own docs. **Public API docs**\ **Yes.** Sovos Docs publishes the Indirect Tax API with authentication, workflows and country guides; some product documentation is gated. [Read the docs](https://docs.sovos.com/en/e-invoicing/indirect-tax-api/connect-to-sovos) **A key you create yourself**\ **No.** You can register and create sandbox apps yourself, but production applications are registered through your Sovos account manager. [docs.sovos.com](https://docs.sovos.com/en/e-invoicing/indirect-tax-api/connect-to-sovos) **Versions or a changelog**\ **Yes.** Endpoints are versioned, and older endpoints are kept in a separate section. [docs.sovos.com](https://docs.sovos.com/en/e-invoicing/indirect-tax-api/older-endpoints/e-archiving-v1/prerequisites) **How it signs in**\ OAuth with an API key and secret from an app in the Sovos developer portal. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Production apps need a Sovos contract and are set up through your account manager. ## What you can build Send invoices from your own system to the tax authority's e-invoicing platform through Sovos, and ask your chat which invoices were rejected. Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Sovos signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Sovos takes more work: ask your chat to check this first. - Sovos covers e-invoicing and tax reporting in many countries through one Indirect Tax API. ## Try it in your chat First get access from Sovos. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Sovos. API docs: https://docs.sovos.com/en/e-invoicing/indirect-tax-api/connect-to-sovos. Read: \[what\]. Write: \[what, or nothing\].
