Utilizes Python Requests and Beautiful Soup libraries to scrape Craigslist postings by keyword search. Listings are written to CSV, and posted to a Slack channel with Slack’s API. A text message is sent using Twilio's REST API if the listing is located in the user's city. Deployed on Heroku’s Cloud service. Note: Per my conversation with Slack's support team, there is a bug where Slackbot posts with unfurled images show as "edited". Their team is currently working on getting this fixed.

External Setup

• Slack workspace
• An App on workspace
• Add chat:write links:write OAuth Token scopes under Add Features and Functionality --> Permissions:
  • 
• Install App to workspace
• Create Channel for bot to post into
• Add bot to channel:
  • 
• Store Slack API in secrets.sh file:
  • export SLACK_API_TOKEN='INSERT-TOKEN-HERE'
• Twilio REST API

Running Planter-Ropot locally on your computer

3. For a scraping of items outside of planters in the SF Bay Area, region and term in line 204 of scraper.py will need to be updated to fit your desired needs. The URL in line 62 can be adjusted according to the Craigslist link you wish to scrape.

4. Source the Slackbot and Twilio API by running the following command:
