# Certificate Of Registration credential schema
## When to use
Use this skill when you issue or ask for a **Certificate Of Registration**. A
business register issues this credential to attest that a company exists: its
registered name and number, its legal form and status, its business activity,
the date of registration, and its registered address. It is a core credential of
a European Business Wallet (EUBW) integration.
The registry publishes this schema in **all three formats**:
| Format | Metadata flag | Identifier to send |
| --- | --- | --- |
| `dc+sd-jwt` | `isSdJwt: true` | `vct` |
| `jwt_vc_json` | `isJwt: true` | `type` |
| `mso_mdoc` | `isMsoMdoc: true` | `doctype` |
This page describes registry version **2025.7.1**, the latest version of the
template.
## Prerequisites
- An **iGrant.io Organisation Wallet Suite (OWS) API key**. Get it from
[support@igrant.io](mailto:support@igrant.io). Keep it on the server, in
an environment variable or a secret manager. The browser never sees it.
- The **OWS environment** the key belongs to. The default is **demo**
(`https://demo-api.igrant.io`). Use **staging**
(`https://staging-api.igrant.io`) only when the integrator asks for it.
A key works only in its own environment.
## Ask the integrator first
Ask one question at a time. Wait for the answer. Give the recommended
default with each question. Look up facts in the project (framework,
environment variables, an existing backend) instead of asking for them.
