+# Stripe Test OAuth Linking
+
+Use this when local tests say the test org has no linked Stripe account, or when Stripe Connect webhooks are visible in Stripe but Autumn cannot map events back to `unit-test-org`.
+
+The Connect webhook destination should be:
+
+```txt
+https://c.autumn.ngrok.app/webhooks/connect/sandbox
+```
+
+OAuth still needs the Autumn org row to store the connected account ID:
+
+```json
+{ "test_stripe_connect": { "account_id": "acct_..." } }
+```
+
+## Commands
+
+List recent connected accounts for the test org email:
+
+```sh
+bun stripe:link-test -- --list --email=unit-test-org@test.com
+```
+
+Link an explicit account:
+
+```sh
+bun stripe:link-test -- --account-id=acct_...
+```
+
+Link the newest account matching the test org email:
+
+```sh
+bun stripe:link-test -- --latest --email=unit-test-org@test.com
+```
+
+If the org has a direct Stripe secret key, `createStripeCli` will prefer that over OAuth Connect. To force the OAuth account for sandbox tests:
+
+```sh
+bun stripe:link-test -- --account-id=acct_... --clear-secret-key
+```
+
+After linking, rerun a focused checkout test before the full suite:
+
+```sh
+ENV_FILE=.env infisical run --env=dev --recursive -- bun test --timeout 0 server/tests/integration/billing/attach/checkout/stripe-checkout/prepaid/stripe-checkout-prepaid-basic.test.ts
+```
