What it takes to connect it to your AI chat with Hypamoon, with sources." url: https://hypamoon.com/connect-to/lloyds-bank --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Lloyds Bank Payments and billing # Connect Lloyds Bank to Hypamoon Possible, with help from Lloyds Bank. The API is documented, but you cannot just create a key: access goes through Lloyds Bank first. Possible ## The check Three questions about the API of Lloyds Bank, answered from its own docs. **Public API docs**\ **Yes.** Lloyds Banking Group implements the UK Open Banking Read/Write API Specification (currently v3.1.10) and publishes its ASPSP documentation through Open Banking. [Read the docs](https://openbanking.atlassian.net/wiki/pages/viewpage.action?pageId=3811999746) **A key you create yourself**\ **No.** Live Open Banking access needs regulatory permission as a provider; there is no self service key for a business's own accounts. [docs.yapily.com](https://docs.yapily.com/institution-configurations/uk/Lloyds) **Versions or a changelog**\ **Yes.** Implemented and planned versions of the Open Banking specification are listed per endpoint. [openbanking.atlassian.net](https://openbanking.atlassian.net/wiki/pages/viewpage.action?pageId=3811999746) **How it signs in**\ OAuth 2.0 and OpenID Connect per the UK Open Banking Standard, with Open Banking Directory certificates. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud **Condition**\ Only regulated providers can connect. A normal business reads its Lloyds accounts through a licensed aggregator, such as TrueLayer (https://docs.truelayer.com/docs/data-api-basics) or Yapily (https://docs.yapily.com/institution-configurations/uk/Lloyds). ## What you can build See your Lloyds business account transactions in your own dashboard through an open banking aggregator, and match incoming payments to 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 - Lloyds Bank signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Lloyds Bank takes more work: ask your chat to check this first. - Lloyds Banking Group (Lloyds, Halifax, Bank of Scotland) offers Open Banking APIs for regulated providers. Business accounts are covered as a separate brand, lloydsbusiness. ## Try it in your chat First get access from Lloyds Bank. Then fill in what to read and write, and send it. Say this in your chat > Build the Hypamoon recipe build-an-adapter for Lloyds Bank. API docs: https://developer.lloydsbanking.com/. Read: \[what\]. Write: \[what, or nothing\].
