## Server Authentication with External Credentials Exchange

:::callout{intent="warning"}
**Use the [Bot Token Endpoint](/guides/provisional-accounts-development-guides-bot-token-endpoint) if your game has an account system that uniquely identifies users.** It is simpler, requires no identity provider configuration, and is the recommended approach for most integrations.

Use External Credentials Exchange only if you have a hard requirement for a server-side custom OIDC integration. If you don't have a server-authoritative backend, use [Public Client Integration](/guides/provisional-accounts-development-guides-public-client) instead.
:::

Before using this method, you must [configure your identity provider](/guides/provisional-accounts-development-guides-identity-providers) in the Developer Portal. Exchange the external provider's token for a Discord access token from your game server:

```python
# filepath: your_game/server/auth.py
import requests

def get_provisional_token(external_token: str):
  response = requests.post(
    'https://discord.com/api/v10/partner-sdk/token',
    json={
      'client_id': CLIENT_ID,
      'client_secret': CLIENT_SECRET,
      'external_auth_type': EXTERNAL_AUTH_TYPE,  # See External Auth Types
      'external_auth_token': external_token
    }
  )
  return response.json()
```

See the [External Auth Types](/guides/provisional-accounts-development-guides-identity-providers#external-auth-types) table for the full list of supported `external_auth_type` values.

#### External Credentials Exchange Response

```python
{
  "access_token": "<access token>",
  "id_token": "<id token>",
  "token_type": "Bearer",
  "expires_in": 604800,
  "scope": "sdk.social_layer"
}
```

:::callout{intent="warning"}
If you are using OIDC, you may see a `refresh_token` in this response. Using it via the OAuth2 `refresh_token` grant is **deprecated** — re-authenticate using a fresh provider token instead. See [Refreshing Access Tokens](/guides/provisional-accounts-development-guides-managing-accounts#refreshing-access-tokens) for details.

### How the Flow Works

```mermaid
sequenceDiagram
    autonumber
    actor P as Player
    participant Prov as External Provider<br/>(OIDC, Steam, EOS)
    participant G as Your Game Server
    participant D as Discord API

    P->>Prov: Authenticate
    Prov-->>G: External auth token
    G->>D: POST /partner-sdk/token<br/>{ client_id, client_secret,<br/>external_auth_type, external_auth_token }
    alt No account for identity
        D->>D: Create provisional account
        D-->>G: 200 { access_token, id_token, ... }
    else Provisional account exists
        D-->>G: 200 { access_token, id_token, ... }
    else Full Discord account exists
        D-->>G: Error 530010 (use OAuth2 flow)
    end
```

Once authentication is complete, you can use the access token as you would a full Discord user's access token. See [Managing Provisional Accounts](/guides/provisional-accounts-development-guides-managing-accounts) for token refresh, storage, and display names.

## Error Handling

Common error codes and solutions when creating a provisional account:

| Code   | Meaning                      | Solution                                                                    |
| ------ | ---------------------------- | --------------------------------------------------------------------------- |
| 530000 | Application not configured   | Contact Discord support to enable provisional accounts for your application |
| 530001 | Expired ID token             | Request a new token from your identity provider                             |
| 530004 | Token too old                | Request a new token (tokens over 1 week old are rejected)                   |
| 530006 | Username generation failed   | Retry the operation (temporary error)                                       |
| 530007 | Invalid client secret        | Verify or regenerate your client secret in the Developer Portal             |
| 530010 | User account non-provisional | User already linked to Discord account - use standard OAuth2 flow           |

If you are using OIDC, you may encounter more specific errors:

| Code   | Meaning                      | Solution                                                                                                               |
| ------ | ---------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| 530002 | Invalid issuer               | Verify the `iss` claim in your ID token exactly matches the issuer URL in your OIDC configuration                      |
| 530003 | Invalid audience             | Verify the `aud` claim in your ID token includes the client ID in your OIDC configuration                              |
| 530008 | OIDC configuration not found | Verify your issuer URL is correct, accessible over HTTPS, and serves a valid discovery document without HTTP redirects |
| 530009 | OIDC JWKS not found          | Verify your JWKS endpoint is accessible over HTTPS without HTTP redirects                                              |
| 530020 | Invalid OIDC JWT token       | Verify your ID token is properly signed and uses a supported algorithm                                                 |
| 530027 | Missing `kid` header         | Ensure your ID token includes a `kid` (Key ID) header in the JWT header identifying the signing key                    |
