## Links

* [Developer Portal](https://developers.ybs.co.uk/)

## Scopes

* Account Information 🔒
* Payment Initiation 🔒

## Live Environment

**Precondition**: To connect to live Open Banking entities, whether you are accessing account information or initiating payments, your business must have the right regulatory permissions as per the [Open Banking Guide](/tools-and-services/open-banking/enrolment-guide).

1. Upload your transport and signing certificates (PEMs) created in the Open Banking directory, along with the keys into Yapily's [certificate vault](https://console.yapily.com/certificates).

2. Add **Chelsea Building Society** from the **Live** tab to your Dashboard application and add your `Signing key Id`, which can be obtained from the Open Banking Directory.

3. Select your Open Banking transport and signing certificates from the relevant drop-downs lists then click *Next*.

4. **Click to register** to auto-register with the bank. If registration is successful, the key and secret will be populated from the institution's response.

5. Make sure to click *Save* in order not to lose these credentials, as a further registration attempt with the same Open Banking software statement is likely to fail.

**Note:** If you first register with *Yorkshire Building Society* use the same credentials to connect to *Chelsea Building Society* by just coping the key and secret
