# Generic Integration Module
The [`GenericIntegrationModule`](https://docs.rs/subscan/latest/subscan/modules/generics/integration/struct.GenericIntegrationModule.html) is primarily used for simple `API` integrations. To understand how it works, check the source code on the [docs.rs](https://docs.rs/subscan/latest/subscan/modules/generics/integration/struct.GenericIntegrationModule.html) page. Additionally, looking at the source code of other modules that use this implementation will help you understand how to utilize it
A module that uses this one internally would look like the following
```rust,ignore
pub const EXAMPLE_MODULE_NAME: &str = "example";
pub const EXAMPLE_URL: &str = "https://api.example.com/api/v1";
pub struct ExampleModule {}
impl ExampleModule {
pub fn dispatcher() -> SubscanModuleDispatcher {
let requester: RequesterDispatcher = HTTPClient::default().into();
let extractor: JSONExtractor = JSONExtractor::new(Box::new(Self::extract));
let generic = GenericIntegrationModule {
name: EXAMPLE_MODULE_NAME.into(),
auth: AuthenticationMethod::NoAuthentication,
funcs: GenericIntegrationCoreFuncs {
url: Box::new(Self::get_query_url),
next: Box::new(Self::get_next_url),
},
components: SubscanModuleCoreComponents {
requester: requester.into(),
extractor: extractor.into(),
},
};
generic.into()
}
pub fn get_query_url(domain: &str) -> String {
format!("{EXAMPLE_URL}/{domain}/subdomains")
}
pub fn get_next_url(_url: Url, _content: Content) -> Option<Url> {
None
}
pub fn extract(content: Value, _domain: &str) -> Result<BTreeSet<Subdomain>> {
if let Some(items) = content["items"].as_array() {
let filter = |item: &Value| Some(item["hostname"].as_str()?.to_string());
return Ok(items.iter().filter_map(filter).collect());
}
Err(JSONExtract.into())
}
}
```
