Maintain, debug, or migrate a LEGACY Corppass integration — the pre-FAPI 2.0 Corppass Authorization API (entityInfo/userInfo ID-token claims, the comma-separated sub format, /authorization-info, Bearer access tokens, esrvcID) or Myinfo Business v1/v2 (/entity-person, PKI_SIGN, client_secret). Use this whenever an existing Corppass integration predates March 2026, when code or API responses reference CPEntID, CPAccType, ISSPHOLDER, TPAuthInfo, ESrvc_Row_Count, or authmode — even inside an…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Corppass legacy: maintain and migrate pre-FAPI 2.0 integrations

Every Corppass integration onboarded before 23 March 2026 runs on the legacy
Corppass Authorization API. It still works, but it has fixed migration deadlines:

| What you have | Deadline | After that |
|---|---|---|
| Legacy Corppass Authorization API | **migrate by 31 March 2027** | legacy security profile deprecated **1 April 2027** |
| Myinfo Business v1/v2 | **migrate to v3 by 31 May 2027** | v1/v2 deprecated |

Submit your migration plan (current progress + target date) at
https://go.gov.sg/cp-fapi-migration-plan. New services cannot onboard to legacy; for
anything greenfield, use the **sg-gov-corppass** skill. This skill covers two jobs:
keeping an existing legacy integration working until it migrates, and executing the
migration correctly.

## Source and currency

How to install

The exact contents, by fingerprint

mdr add kyleoliveiro/sg-gov-skills/sg-gov-corppass-legacy@sha256:d3d26d05c43f8cfb

The line at the top of this page pins the label git:20261027.6f21efa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
