# 4b. Create a Trusted URL

{% hint style="info" %}
NOTE: This step is new due to Salesforce tightening their Content Security Policy (CSP) settings on June 16, 2025.
{% endhint %}

Go to **Setup** > **Security** > **Trusted URLs** and click the **New Trusted URL** button.

When creating the Trusted URL:

* [ ] **API Name:** enter *SlapFive*.
* [ ] **URL:** type *https\://\*.slapfive.com*. The wildcard is needed to handle different subdomains such as app.slapfive.com, your\_client\_name.slapfive.com, and auth.slapfive.com.
* [ ] **CSP Context:** Leave set to *All*.
* [ ] **CSP Directives:** Check all 6 checkboxes. The critical CSP Directive is *frame-src (iframe content)*, but the iframe can also contain these other elements. 

Click the **Save** button to create the new Trusted URL.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.slapfive.com/integrations/salesforce/slapfive-app-spring-2024-4.0-and-earlier-versions/4b.-create-a-trusted-url.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
