# Using integrations in the widget
Help for the people at your customer who use the integrations widget - connecting apps, customizing integrations, alerts and sync status.
Where this fits: stage 4 of the integration lifecycle
These tutorials are for the people at your customer who use integrations through the widget embedded in a SaaS product. You don't need a fastn account or dashboard access - everything happens inside the product you already use.
{% hint style="info" %}
**Note for SaaS companies:** Share this section with your customers when they ask how to use the integrations you've embedded. These tutorials describe the customer experience in the widget, not the fastn dashboard.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.fastn.ai/for-your-customers/end-user.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
