# Go live

> Here are the four steps between a working sandbox integration and real money.

If your integration works in sandbox, it works in production. Going live is four steps, not a migration.

## The checklist

1. **Subscribe.** In the [dashboard](https://app.agentcard.sh) or with `agent-cards companies subscribe`. The subscription is what unlocks production.
2. **Create production credentials.** A production `client_id` and `client_secret` from **Settings → Developers → Credentials**. Nothing else in your code changes; the base URL stays `api.agentcard.sh`.
3. **Point webhooks at production.** Create a production webhook endpoint and verify signatures against its own secret. Sandbox and production endpoints are separate.
4. **Run the loop once with real money.** Connect a real user, add a real card, make a small real purchase. Watch the same webhooks you saw in sandbox arrive with `livemode: true`.

## The gate fires at use time

You can create production credentials before subscribing, and they will authenticate. What they can't do is act: calls that create wallet links, add cards, or issue cards fail with `subscription_required` (HTTP 402) until the subscription is active. If production suddenly returns 402 where sandbox worked, this is why.

## What changes with real money

* Identity verification is real: documents and a face check, no simulate endpoint.
* Card eligibility is enforced for real. Almost any credit or debit card works; the known exception today is Chase.
* Balance funding uses real payment providers, including ones sandbox can't simulate.
* The one-time code is never `111111` again.
