How to extract e-mail addresses from websites

25min
Scenario: From different websites you will extract all email addresses using a third party Web-Scraping API tool. The extracted information will be moved to a spreadsheet software in this case “SmartSheet”

Let's build this process!
In this scenario we have three elements:
Third party API webscraping tool: https://app.scrapingbee.com/ 
Third party spreadsheet software: https://app.smartsheet.com/﻿
Postman
PROCESIO: https://procesio.app/﻿
ScrapingBee
Using a free account to obtain your API key.
Step 1. Go to https://app.scrapingbee.com/, log into your account and from your dashboard make sure you are able to obtain your API key. 
This API key will be used later when creating an REST API credential in PROCESIO.
Obtaining API key from ScrapingBee
﻿
SmartSheet
Step 1. Go to https://app.smartsheet.com/﻿, and log in. From the home screen click on create.
﻿
﻿
Step 2. Select the sheet type to be of type Grid, once selected name the Sheet and hit ok.
SmartSheet Grid Type
﻿
Step 3. In SmartSheet a sheet of type Grid will open. In this sheet we will only keep the first two columns. (Remove Columns 3-6, by selecting them, right click and hitting delete column)
﻿
Step 4. Obtain your API key from SmartSheet by clicking Account -> Personal Settings -> API Access -> Generate new access token. Once API key generated, keep it at hand for later use.
﻿
Postman
We will use Postman in order to obtain the column IDs of the SmartSheet, spreadsheet software in which we will write the extracted e-mail addresses from the websites.
Step 1. Open Postman, by using SmartSheet API documentation we will add the following get request in Postman
End point: https://api.smartsheet.com/2.0/sheets/{SheetId}
Request method: GET
Body: "{"version": 1}"
Body format: application/json
Headers:
Name
Direction
Type
Value
Authorization
In
String
the Bearer token you kept at hand from SmartSheet Step 4,(eg: Bearer *****)
The Sheet ID can be obtained from SmartSheet by navigating to Browse -> Sheets -> Right click on the Sheet -> Properties
Sheet Id
﻿
Step 2. From the response obtain the column IDs for the two columns in which you will write the data. Highlighted with red in below code box. Keep this two IDs at hand as we will use them in PROCESIO.

﻿
Step 12.  Outside the ForEach, on the Canvas, add a DeDuplicate Action (contained in Platform Actions under the Beta Folder).
﻿
﻿
Configure the Action by (select Action):

Adding in the field List to process, the variable MasterEmailList
Adding to the field Duplicate Identification Json configuration, {"MatchType": "Exact"}
Adding to the field Deduplicated list, the variable MasterEmailList
﻿
﻿
Step 13. Add a second ForEach Action on Canvas.
﻿
Configure the Action by (select Action):
Configure field For Each Item, by typing Iterator2 (this will automatically add a variable of type string to named Iterator2to the field.
Configure field In List by pressing add variable button and adding the variable MasterEmailList

Body:
JSON
[
   {
      "toTop":true,
      "cells":[
         {
            "columnId": your column id,
            "value": <%Increment%>
         },
         {
            "columnId":your column id,
            "value":"<%Iterator2%>"
           
         }
      ]
   }
]
[
   {
      "toTop":true,
      "cells":[
         {
            "columnId": your column id,
            "value": <%Increment%>
         },
         {
            "columnId":your column id,
            "value":"<%Iterator2%>"
           
         }
      ]
   }
]
﻿
Your column id is obtained in Postman Step 2. (posting below a screenshot of how the Body of the Call API looks in PROCESIO
﻿
As observed besides the column Id(s), the body contains two variables: Increment & Iterator2
Additional hit, for inserting in the body of a Call API Action, one ca press INSERT key
﻿
﻿
Step 17. Make sure that all your actions are connected in a sequence. Save the Process, Validate & Run.
﻿
﻿
Step 18. In SmartSheet, check for new e-mail address entries.
