Scrape Product IDs

One of the most useful tips and tricks from my experience is to scrape the target product ID first before using the free API. It’s because generally, the API has a limited quota for you to call every month. For saving costs, we could only use the API to refresh the target product price rather than waste the quotas in scraping the product ID. And as you might be aware, basically free APIs can offer a free quote to scrape product information using product id.

Take Home Depot for example. We could code a SERP scraping first using selenium and your target product keywords. Below is an example we scrape the security camera google nest in the smart home category. You can refer to the home depot search URL parameter structure to code

From this script, we can scrape the product title, price, and ID from the SERP. The ID can be used the moment you set up the automatic price tracker in the other script.

Google Shopping Price Tracker

SERP API provides rich parameters for developers to filter the Google Shopping product information, such as by country, and by language. You can also add the no_cache parameter to get the latest information and enhance the accuracy of the price tracker

from serpapi import GoogleSearch 

params = { 

"engine": "google_product", 

"product_id": "4172129135583325756", 

"gl": "us", 

"hl": "en", 

"api_key": "cf16ea6ebf32764c3c13fae81d14425734dbc6ac776878c373ab80d7fba43bb9" } 

search = GoogleSearch(params) results = search.get_dict() 

product_results = results['product_results'

From the product ID, you can grab the product title, original price, current price, rating, reviews, etc.

Walmart Price Tracker

Similar to Google Shopping product API, you can add the engine parameter value, no_cache, and product ID data you are going to fetch, it’s super straightforward and the data response is fast.

params = {

"engine": 'walmart_product',

"product_id": '808410926',

"api_key": apiKEY,

"no_cache": 'true'

}

search = GoogleSearch(params)

results = search.get_dict()

shopping_results = results['product_result']

Home Depot Price Tracker

Same to the Walmart price tracker, you just need to replace the engine name value and product ID, you can grab the data. The data type from SERP API is a dictionary format. It’s super convenient to select the product information you need. However, the accessible data options are slightly different from Walmart. Please go to SERP API documentation to double-check, you can’t just copy and paste the Walmart code used to Home Depot.

params = {

"engine": 'home_depot_product',

"product_id": productID,

"api_key": apiKEY,

"no_cache": 'true'

}

search = GoogleSearch(params)

results = search.get_dict()

shopping_results = results['product_results']
