# Authorize endpoint data provider
Use this plugin to configure the OAuth2 provider to return additional data from an authorization request, such as data from the user's session or from an external service.
* Default script
To view the default script, including the available script properties, refer to [oauth2-authorize-endpoint-data-provider.js](../am-scripting/sample-scripts.html#oauth2-authorize-endpoint-data-provider-js).
To view or modify the default script in the AM admin UI, go to Realms > *realm name* > Scripts and select OAuth2 Authorize Endpoint Data Provider Script.

## Example authorization endpoint data provider plugin
Complete the following steps to implement an authorization endpoint data provider script that returns custom user session data:
1. [Configure the authorization endpoint data provider script](#config-auth-endpoint-plugin)
2. [Configure AM to use the authorization endpoint data provider script](#configure-auth-endpoint-plugin)
3. [Create an OAuth2 client for authorization](#create-oauth2-client)
4. [Try the sample authorization endpoint data provider plugin](#try-auth-endpoint-plugin)

| - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| | To configure AM to use a *Java* authorization endpoint data provider plugin, refer to [Configure AM to use a Java OAuth 2.0 plugin](customizing-oauth2-scopes.html#configure-java-oauth2-plugin). |
### Configure the authorization endpoint data provider script
This task describes how to modify the default script to retrieve additional fields. To create a new script instead, refer to [Manage scripts (UI)](../am-scripting/manage-scripts-console.html), and reference the new script name when you configure the provider.
1. In the AM admin UI, go to Realms > *realm name* > Scripts, and click OAuth2 Authorize Endpoint Data Provider Script.
2. In the Script field:
* Enable the script by removing, or commenting out as in this example, the following block comments surrounding the function, on lines 40 and 90:
```javascript
// /* EXAMPLE
...
// */
```
* For the purposes of this simple test, comment out the call to add data from a third party service:
```groovy
//addAdditionalDataFromExternalService();
```
3. Save your changes.
The default authorization endpoint data provider script is now amended to return a static key/value pair, `"hello": "world"`, and to get the user's IP address from the session data.
### Configure AM to use the authorization endpoint data provider script
Perform this task to set up an OAuth2 provider to use the authorization endpoint data provider script.
1. [Configure the provider](customizing-oauth2-scopes.html#configure-scripted-oauth2-plugin) and ensure the following properties are set:
* Authorize Endpoint Data Provider Plugin Type to `SCRIPTED`.
* Authorize Endpoint Data Provider Script to `OAuth2 Authorize Endpoint Data Provider Script`.
If you created a new script rather than editing the default, you need to reference the new script name here.
2. Save your changes.
### Create an OAuth2 client for authorization
Create an OAuth 2.0 client to use in the authorization request.
1. In the AM admin UI, go to Realms > *realm name* > Applications > OAuth 2.0 > Clients, and click Add Client.
2. Enter the following values:
* **Client ID**: `myClient`
* **Client secret**: `mySecret`
* **Redirection URIs**: `https://www.example.com:443/callback`
* **Scope(s)**: `access|Access to your data`
3. Click Create.
AM is now prepared for you to perform an OAuth2 authorization request to try the sample plugin.
### Try the sample authorization endpoint data provider plugin
1. Log in to AM as a test user, for example:
```bash
$ curl \
--request POST \
--header "Content-Type: application/json" \
--header "X-OpenAM-Username: bjensen" \
--header "X-OpenAM-Password: Ch4ng31t" \
--header "Accept-API-Version: resource=2.0, protocol=1.0" \
'https://am.example.com:8443/am/json/realms/root/realms/alpha/authenticate'
{
"tokenId":"AQIC5wM…TU3OQ*",
"successUrl":"/am/console",
"realm":"/alpha"
}
```
Note the SSO token value returned as `tokenId` in the output.
2. Invoke the authorization server's [/oauth2/authorize](oauth2-authorize-endpoint.html) endpoint specifying the SSO token value in a cookie, and the following parameters:
* **client_id**=`myClient`
* **response_type**=`code`
* **redirect_uri**=`https://www.example.com:443/callback`
* **decision**=`allow`
* **csrf**=*SSO-token*
For example:
```bash
$ curl --dump-header - \
--request POST \
--cookie "iPlanetDirectoryPro=AQIC5wM…TU3OQ*" \
--data "scope=access" \
--data "response_type=code" \
--data "client_id=myClient" \
--data "csrf=AQIC5wM…TU3OQ*" \
--data "redirect_uri=https://www.example.com:443/callback" \
--data "state=abc123" \
--data "decision=allow" \
"https://am.example.com:8443/am/oauth2/realms/root/realms/alpha/authorize"
```
If the authorization server is able to authenticate the user and the client, it returns a successful HTTP 302 response, for example:
```bash
HTTP/1.1 302 Found
Server: Apache-Coyote/1.1
X-Frame-Options: SAMEORIGIN
Pragma: no-cache
Cache-Control: no-store
Date: Mon, 30 Jul 2018 11:42:37 GMT
Accept-Ranges: bytes
Location: https://www.example.com:443/callback?code=g5B3qZ8rWzKIU2xodV&ipAddress=127.0.0.1&scope=access&iss=https%3A%2F%2Fam.example.com%3A8443%2Fam%2Foauth2&hello=world&state=abc123&client_id=myClient
Vary: Accept-Charset, Accept-Encoding, Accept-Language, Accept
Content-Length: 0
```
As the example output indicates, the parameters injected by the authorization endpoint data provider script, `ipAddress=127.0.0.1` and `hello=world`, are both appended to the redirect URL.
## Authorization endpoint data provider scripting API
The following properties are available to authorization endpoint data provider scripts.
| Binding | Description |
| ------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `httpClient` | An HTTP client for making external HTTP requests. |
| [`logger`](customizing-oauth2-scopes.html#logger) | The logger instance for the script.Logger names use the format `scripts.OAUTH2_AUTHORIZE_ENDPOINT_DATA_PROVIDER.
