# Send Apex context to a JavaScript search interface (Deprecated)
[.version.no-link.classic]
Salesforce Classic

> **Deprecated**
>
> This feature is still available, but no longer supported as of the August 2023 release of Coveo for Salesforce version [5.2](https://docs.coveo.com/en/n5bj0150#august-2023-release-v5-2-initial-release).

You may want to have access to some Apex variables in your JavaScript Search interface.
You can use the search context, a map of Apex values to do this as shown in the following example.

**Example**

In an on-premises Coveo REST Search API, you define a trusted application with its `secret key`.
You want to use the `secret key` to request a search token from your Apex page, and then use the received search token in your JavaScript search interface to set the `accessToken` to authorize the page to communicate with the REST Search API.

Here is how to do that:

. In Salesforce, create an Apex class (see [Adding an Apex Class](https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_qs_class.htm)) that allows you to get the token and create a search context with the token in it.

```apex
public class MySearchController {
​
  class UserId{
    public String name {get; set;}
    public String provider {get; set;}
    public String type {get; set;}
    public UserId(String name, String provider, String type){
        this.name = name;
        this.provider = provider;
        this.type = type;
    }
  }
​
  class TokenResponse {
    public String token;
  }
​
  public SearchContext getContext(){
    HttpRequest req = new HttpRequest();
    req.setEndpoint('https://YouRestApiUrl/rest/search/token');
    req.setMethod('POST');
    req.setHeader('Authorization', 'Bearer the_secret_key_for_the_application');
    req.setHeader('Content-Type', 'application/json');
​
    List<UserId> userIds = new List<UserId>();
    userIds.add(new UserId('foo@bar.com', 'Email Security Provider', 'User'));
​
    Map<String,Object> body = new Map<String, Object>();
    body.put('userIds', userIds);
    req.setBody(JSON.serialize(body));
​
    req.setTimeout(10000);
​
    Http http = new Http();
    HTTPResponse res = http.send(req);
​
    System.debug(res.getBody());
​
    String token = ((TokenResponse)JSON.deserialize(res.getBody(), TokenResponse.class)).token;
​
    SearchContext context = new SearchContext();
    context.put('token',token);
    return context;
  }
}
```

. Create a new Visualforce page (see [Defining Visualforce Pages](https://help.salesforce.com/apex/HTViewHelpDoc?id=pages_creating.htm)) that adds the search context in the component from the controller.

```xml
<apex:page standardstylesheets="false" sidebar="false" docType="html-5.0" controller="MySearchController">
    <Coveo:SearchInterface mobile="false" searchContext="{!context}" />
</apex:page>
```

. Using the Interface Editor (see [Accessing the Interface Editor for a Search API Hosted Page](https://www.coveo.com/go?dest=adminhelp70&lcid=9&context=1032)):

.. Select the **Advanced Mode**, and then select the **Code** tab.

.. In the page code, add the following code to set the token in the search interface endpoint options.

```html
<script type="text/javascript">
  $(function(){
    Coveo.Rest.SearchEndpoint.endpoints['default'].options.accessToken = Coveo.context.token
  })
</script>
```
