What it takes to connect it to your AI chat with Hypamoon, with sources." url: https://hypamoon.com/connect-to/commerzbank --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Commerzbank Payments and billing # Connect Commerzbank to Hypamoon Possible, with help from Commerzbank. The API is documented, but you cannot just create a key: access goes through Commerzbank first. Possible ## The check Three questions about the API of Commerzbank, answered from its own docs. **Public API docs**\ **Yes.** The Commerzbank Developer Portal has a quickstart guide, an API catalog and sandbox specs, including a Corporate Payments API for corporate and small business customers. [Read the docs](https://developer.commerzbank.com/how-to/quickstart-guide) **A key you create yourself**\ **No.** You create a project and sandbox credentials yourself, but live use is requested through the portal, then Commerzbank sends a contract and issues a client certificate from your CSR. [developer.commerzbank.com](https://developer.commerzbank.com/how-to/quickstart-guide) **Versions or a changelog**\ **Yes.** APIs carry a version in their path, such as customers-api v2 and securities-api v4. [developer.commerzbank.com](https://developer.commerzbank.com/products/api-catalog) **How it signs in**\ OAuth 2.0 with credentials from your portal project, over mutual TLS with a client certificate issued by Commerzbank. **Webhooks**\ **Yes.** It can tell your app when something changes. [developer.commerzbank.com](https://developer.commerzbank.com/how-to/quickstart-guide) **Hosting**\ Cloud **Condition**\ Live use needs a signed contract with Commerzbank and a client certificate that Commerzbank issues. ## What you can build Collect account information and send payments from your own cash management or ERP through the Corporate Payments API, with you approving every payment. 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 - Commerzbank signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Commerzbank takes more work: ask your chat to check this first. - The Corporate Payments API is meant for corporate and small business customers who connect their own systems. A Webhook API exists, with certificate pinning. ## Try it in your chat First get access from Commerzbank. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Commerzbank. API docs: https://developer.commerzbank.com/how-to/quickstart-guide. Read: \[what\]. Write: \[what, or nothing\].
