Hey Yurii - First, since you want to make requests to the API with different URL endpoints, I suggest using the API Enrichment step instead of the API Import step.
You would want to import a table of the list of domains you listed in #1, whether it be a Google Sheet, CSV, or Excel file.
Then, in your API Enrichment step, you’ll want you API endpoint to look like this: https://awis.api.alexa.com/api?Action=UrlInfo&Count=10&ResponseGroup=Rank,LinksInCount&Start=1&Url={column_name_of_domain}
Be sure to update what’s inside the curly braces {} based on your own column name.
For authenticating the API Enrichment step, select None in the Authentication dropdown.
Instead we’re going to create two custom headers.
Header Key: Accept
Header Value: application/xml
Header Key: x-api-key
Header Value: your own API key
Note that you can type in values to the Header Key field. You don’t have to select from the dropdown.
