This article picks up from the end of Part 4: Using the URL Generator.
With both our listings and details extractors created, you then can chain the extractors together to take the URLs collected in the listings extractor and extract data from them using the details extractor
To do this, go to the Details extractor and in the Extract from drop-down menu, choose columns from another extractor. This will reveal the option to set a Parent Extractor, which sets the extractor to pull the URLs from. After setting the option to your listings extractor, it will prompt you to select the URL column that the URLs are present in.
With the chain setup, you also have the option to set it to Always run the parent first, which means everytime you trigger that extractor or its parent extractor, it will run them both in order. With that option enabled, you can then click the Save Input Mapping button. Click Run Inputs to run our listings extractor and then run our details extractor.
After the extractors finish running, you will want to move on to Part 6: Downloading Your Data.
