What your AI chat can build with it on Hypamoon, how it connects, and the sources we checked." url: https://hypamoon.com/connect-to/toconline --- 1. [Connect to](https://hypamoon.com/connect-to) 2. TOConline ERP and accounting # Connect TOConline to Hypamoon Yes, with one catch. TOConline has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of TOConline, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://api-docs.toconline.pt/) **A key you create yourself**\ **Yes.** A business owner gets the client ID, secret and URLs in TOConline under Empresa, Configurações, Dados API, and can send them to a chosen integrator through a 72 hour link. [api-docs.toconline.pt](https://api-docs.toconline.pt/autenticacao-detalhada) **Versions or a changelog**\ **Yes.** The docs keep a section for earlier API versions, and the OpenAPI file is versioned (1.0.0). [api-docs.toconline.pt](https://api-docs.toconline.pt/apis/versoes-anteriores) **How it signs in**\ OAuth 2.0 authorization code flow with the client ID and secret from Dados API, then a bearer access token. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## In practice What it takes in a real TOConline administration. **Getting access**\ Download the API configuration file under Empresa, Dados API in TOConline. **Limits**\ None published. **Writing**\ **Not confirmed.** **Cost**\ Not published. ## What you can build Create sales documents in TOConline from your own order flow, and ask your chat which customers still have open invoices. 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 - TOConline signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for TOConline takes more work: ask your chat to check this first. - The API covers company data, sales and purchases. A Postman configuration file comes with the credentials. ## Try it in your chat Fill in what to read and write, and send it.
