For more information about products please see [the reference](#products) ## Query Products for Location - [POST /queryProductsForLocation](https://ala-api.docs.cityfibre.com/openapi/products/queryproductsforlocation.md): Check the available products for a given location using the location's UPRN. The seller will then respond with a list of one or multiple available products (if any) along with information about the need for an appointment (yes/no/maybe). For more information on products see the reference Some products such as auxiliary services could depend on other products (this is indicated via the dependsOn property). For example ResVOIP1 can depend on CPEInst1, meaning if ResVOIP1 is ordered then CPEInst1 needs to be requested as well.
