# Get wallet by external ID

> Look up a wallet using its external ID with the ext_wal_ prefix

If a wallet has an [external ID](/wallets/wallets/external-ids), your app can use the `ext_wal_` prefix in place of the wallet ID to look it up. Prefix `ext_wal_` to the external ID value to form the identifier.

For example, if a wallet has `external_id` set to `order-12345`, your app can reference it as `ext_wal_order-12345`:

```bash theme={"system"}
curl --request GET https://api.privy.io/v1/wallets/ext_wal_order-12345 \
    -u "<your-privy-app-id>:<your-privy-app-secret>" \
    -H "privy-app-id: <your-privy-app-id>"
```

The `ext_wal_` prefix works on all wallet endpoints that include a wallet ID in the path, including [get wallet by ID](/wallets/wallets/get-a-wallet/get-wallet-by-id), [update wallet](/wallets/wallets/update-a-wallet), and RPC endpoints.

<Info>
  When using [authorization signatures](/api-reference/authorization-signatures), sign the request
  using the URL exactly as sent, including the `ext_wal_` prefix.
