# Reference
## Schema Documentation
Our schema documentation lists all the content of our GraphQL API's schema. So you'll find all the queries and mutation that are available, as well as a description of the types manipulated by the API.
Do note that Apollo offers the same capabilities, but where Apollo requires to be authenticated with a valid iAdvize account, the static documentation is available and shareable publicly.
## Apollo
You can discover the schema and run queries on your iAdvize data using Apollo, an integrated development environment in your browser that includes the schema description, syntax highlighting, and validation errors.
### Using Apollo
#### Authentication
You'll need to be authenticated in order to test queries. If you weren't already, you'll automatically be prompted to sign-in when reaching the Apollo page, after which you'll be able to continue using the query editor.
You can test your access by querying your projects:
query {
projects {
edges {
node {
id
name
}
}
}
}
{% hint style="info" %}
[Test this query in our editor](https://ha.iadvize.com/apollo?explorerURLState=N4IgJg9gxgrgtgUwHYBcQC4QEcYIE4CeABMADpJFEAOeEAVglCgM4nmWUJgDmCrZFDpSQQwCNoKGUAlmHZThAQ0TyhAX1VENg7WpBqgA)
{% endhint %}

# Agent Instructions: 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:
```
GET https://docs.iadvize.dev/technologies/graphql-api/reference.md?ask=
```
The question should be specific, self-contained, and written in natural language.
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.
