How to extract e-mail addresses from websites

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:

1. Third party API webscraping tool: https://app.scrapingbee.com/
2. Third party spreadsheet software: https://app.smartsheet.com/
3. Postman
4. 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.

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.

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:

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.

PROCESIO (Create process that extracts e-mail addresses)

There are multiple actions involved in extracting e-mails from a website. The complete process should look like this:

Step 1. From within PROCESIO go to "Credential Manager", press the Add new button and use these values:

Name: ScrapingBee Credential type: REST API Configuration Step 2. Press the Next step button and use these values: URL: https://app.scrapingbee.com Method: GET Test endpoint: /api/v1 Authentication method: API key authentication Key: api_key

Value: Your API Key obtained at ScrapingBee Step 1

Step 3. Press the Save button

Step 4. From within PROCESIO, "Credentials Manager, press the Add new button and use these values: Name: SmartSheet Credential type: REST API Configuration URL: https://api.smartsheet.com Method: GET Test endpoint:/2.0/sheets Authentication method: API key authentication Key: Authorization

Value: Bearer Your API Key obtained at SmartSheet Step 4



Step 5. Add a ForEach Action, name it's node ForEach site.

Configure the Action by (select Action):

• Configure field For Each Item, by typing Iterator (this will automatically add a variable of type string to named Iteratorto the field.
• Configure field In List by pressing add variable button-> Create New Variable, URLList. Once the variable is created select it to this field.

• Configure field Action timeout, by typing 600 (this impies that after 600 seconds, the process will timeout)

Step 6. Inside the ForEach frame previosly named "ForEach site", add a Call API Action and in the side panel set the Node name to ScrapingBee Step 7. In Select API configuration select ScrapingBee

Step 8. Press the Configure Request button and add these values:

Verb: Get Endpoint: /api/v1 Query Params:

Form Configure Request, for the Status Output field, add a variable named StsOut of type integer, by clicking the Add Variable button-> Create New Variable. Once the variable is created select it to this field.

Form Configure Request, for the Body Output field, add a variable named HTMLObjectOut of type object, by clicking the Add Variable button-> Create New Variable. Once the variable is created select it to this field.

Step 9. Inside the ForEach frame previously named "ForEach site" , add a Map Process Data Action.

Configure the Action by (select Action):

• Adding in the right input field, the variable HTMLObjectOut
• Adding in the left input field a new variable named HTMLString by hitting the Add Variable button-> Create New Variable. Once the variable is created select it to this field.

Step 10. Inside the ForEach frame previously named "ForEach site" , add a RegEx Extract Action (contained in Platform Actions under the Beta Folder).

Configure the Action by:

• Adding in the field String to Extract from, the variable HTMLString
• Adding to the field Regex Expression ([_\.0-9a-zA-Z-]+@([\-0-9a-zA-Z]+\.)+[a-zA-Z]{2,6})
• Adding to the field Lists of results a new variable named EmailList by hitting the Add Variable button-> Create New Variable. Once the variable is created select it to this field.



Step 11. Inside the ForEach frame previously named "ForEach site" , add a Concatenate Lists Action (contained in Platform Actions under the Beta Folder). Configure the Action by:

• Adding in the field First List, a new variable named MasterEmailList by hitting the Add Variable button-> Create New Variable. Once the variable is created select it to this field.

• Adding in the field Second List, the variable EmailList
• Adding in the field Concatenated List, the variable MasterEmailList

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
• Configure field Action timeout, by typing 600 (this impies that after 600 seconds, the process will timeout)



Step 14. Inside the second ForEach frame, add an Add operation Action.

Configure the Action by (select Action):

• Adding in the field First Number, a new variable named Increment by hitting the Add Variable button-> Create New Variable. Once the variable is created select it to this field.

• Adding in the field Second Number, the value: 1
• Adding in the field Result, the variable Increment



Step 14. Inside the second ForEach frame, add an Call API Action and in the side panel set the Node name to SmartSheet

Step 15. In Select API configuration select SmartSheet

Step 16. Press the Configure Request button and add these values:

Verb: POST Endpoint: /2.0/sheets/{Your Sheet ID}/rows

• {Your Sheet ID} was obtained in Postman Step1.



Body:



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.
