A dedicated authentication and connection layer that handles HMRC's OAuth 2.0 requirements directly on your IBM Power server, running natively under IBM i. Token issuing, renewal and encrypted transport — all managed on the platform your data already lives on.
The OAuth Connector is installed directly on your IBM Power server and runs natively under IBM i. Access tokens, refresh tokens and client credentials are generated, stored and renewed on your own system — there's no third-party broker sitting between your business and HMRC.
Purpose-built for IBM i, the OAuth Connector handles the authentication HMRC requires so your other applications don't have to.
Implements the full OAuth 2.0 authorisation code flow required by HMRC's Making Tax Digital APIs, run natively on your IBM i system.
Access and refresh tokens are encrypted and held on your own IBM Power server, never passed through or cached by a third party.
Refreshes access tokens ahead of expiry in the background, so connected applications keep submitting without manual re-authorisation.
All traffic between your IBM i system and HMRC's gateway is encrypted in transit, meeting HMRC's connection security standards.
Every authorisation, token refresh & API call is logged on IBM i, giving you a complete record of access to HMRC on your behalf.
Built to be shared by your MTD VAT Portal and other HMRC-connected applications, so authentication is managed in a single place.
The OAuth Connector handles the security handshake so your applications only ever see a ready-to-use connection.
The OAuth Connector is deployed directly onto your existing IBM Power hardware, running natively under IBM i alongside your other applications.
A one-time authorisation grants the connector permission to act on your behalf, following HMRCs standard OAuth 2.0 consent flow.
Access tokens are issued, encrypted & stored on your IBM i server, with automatic renewal so connections don't expire mid-process.
Connected applications like the MTD VAT Portal call HMRC through the connector, which attaches a valid wowtoken to every request.
Once authorised, the connector keeps the connection alive without anyone needing to step in.
HMRC grants an access token and refresh token after successful authorisation.
Tokens are encrypted and stored locally on your IBM i system, not in any external service.
Every call to HMRC from a connected application carries a valid, current access token.
The connector renews tokens automatically ahead of expiry, with no interruption to service.
Keeping authentication on the same system as your data removes an entire category of external risk.
