Home Depot API Adapter

This is a POC to query data from Home Depot's GraphQL isntance to get item and pricing data. I am trying to monitor for the lowest price on items like lumber, and sometimes they fluctuate a lot. All you need to run the check is the store ID and zipcode. With the API response you could theoretically monitor for lowest price.

Behind the scenes

To pull the item data from the hydration API, you need to POST data to the endpoint requesting details for an item at a particular store and zipcode. Below is a sample JSON POST request to the endpoint.

{
    "operationName": "productClientOnlyProduct",
    "variables": {
        "skipSpecificationGroup": false,
        "skipSubscribeAndSave": false,
        "skipKPF": false,
        "itemId": "305418731",
        "storeId": "534",
        "zipCode": "77449"
    },
    "query": "query productClientOnlyProduct(.....)"
}

We pull the graphql query from the file query.dat file, since we're not changing that data on the fly and it's a large amount of data.
