The Keepa Amazon price tracker API offers large number of data points for Amazon products. Our free "Keepa API Connector" addon helps downloading Asins using seller or category id. You can also download buybox price, 30 days average, monthly sold quantity, title, model, brand and weight(kg) using our "Asin Lookup" feature.  You can select any marketplace; it works for both buybox types (used and new).

To start, first click "Register". Once registration is done please reload spreadsheet. Load addon and click "Config" and enter your Keepa API key, select your most used marketplace then click "Save". Click "Test" to confirm your entered API key is correct. 

Now you are ready to download data from Keepa. Click "Keepa", to download Asins by seller id, go to "Find Asin" section. Select “By Seller ID" from dropdown, enter seller id and click "Run", soon you will see Asins downloaded in column A of your opened sheet. 
Similarly, you can select "Category ID" from dropdown and enter category id in the text box and click "Run". To download Asin lookup data, enter your target Asins in column A of your sheet starting from row 2, go to "Asin Lookup" section, select buybox type and click "Run". Soon Asin lookup data will start downloading, maximum 100 Asins lookup data will download on single click if enough Keepa tokens are available.
