With sources." url: https://hypamoon.com/connect-to/billtrust --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Billtrust Payments and billing # Connect Billtrust to Hypamoon We could not confirm it. Billtrust passes some of our checks, but not all three could be confirmed from its own docs. Unknown ## The check Three questions about the API of Billtrust, answered from its own docs. **Public API docs**\ **Not confirmed.** No public API documentation could be opened; billtrust.com mentions connectors and an MCP server. **A key you create yourself**\ **Not confirmed.** **Versions or a changelog**\ **Not confirmed.** **How it signs in**\ Not publicly documented on the pages we could open. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## What you can build Push invoices from your own system into Billtrust and pull payment status back, so your chat can tell you which customers have paid. 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 - Billtrust connects to ERPs through its own connectors and offers an MCP server for AI assistants. Ask Billtrust which API access your contract includes. ## Try it in your chat First get access from Billtrust. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Billtrust. API docs: . Read: \[what\]. Write: \[what, or nothing\]. [Open in Claude](https://claude.ai/new?q=Build%20the%20Hypamoon%20recipe%20build-an-adapter%20for%20Billtrust.%20API%20docs%3A%20.%20Read%3A%20%5Bwhat%5D.%20Write%3A%20%5Bwhat%2C%20or%20nothing%5D.) In Claude, or another chat with the full Hypamoon connection; adapters are not in ChatGPT yet. You paste the key in the portal, never in the chat.

Say this in your chat > Check if \[software\] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog.
