4. make directory whatever u want, in here fchatbot-kotlin then go inside and make directory again

   • src/main/kotlin/com/baihaqilp/fchatbot (this for package name so in the program will be "package com.baihaqilp.fchatbot") -src/main/kotlin/resources

5. make build.graddle inside fchatbot-kotlin dir

6. go inside directory fchatbot-kotlin then install gradlewrap

   • gradle wrapper --gradle-version = 5.5.1

7. make build.graddle like this.

9. make config.properties inside src/main/com/resources app_id=app id here verify_token=verify token here page_access_token=access token here log_console_status=false log_console_level=ALL log_file_status=false log_file_level=ALL log_file_path=src/main/java/resources/app.log log_file_limit=1 log_file_count=200000 log_file_append=true

10. open 2 terminal, 1 for "./gradlew run" and 1 for "./ngrok http 4567"

11. create a facebook page

12. create a facebook app Go to the Facebook Developer Page and click “Skip and Create App ID” at the top right. Then create a new Facebook App for your chat bot and give your app a name and contact email.

    You can get the app id and insert that id in config.properties file you created

13. choosee messenger . From the Messenger settings for your Facebook App, You can connect your app with the facebook page to get access token.

14. Then we need to setup our webhook like the following:

15. Please note that, You can set Verify Token to be any value and pass that value to our config.properties file and restart our app (Just stop it and run ./gradlew run).

Then click Verify and Save.

16. After you’ve configured your webhook, Just subscribe to the specific page you want to receive message notifications for.
