Slack Integration
4.1 Activate the WebHooks in your WorkSpace and get the corresponding 'WebHook URL'
4.2 In server.js, set the 'WebHook URL' in SLACK_WEBHOOK_URL = 'https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX';
SendGrid Email Integration
5.1 Create a SendGrid Free Account
5.2 Create and get an API KEY with Full Access
5.3 In server.js, set the 'API KEYS' in SENDGRID_APY_KEY = 'AA.AAAA_AAAAAAAAAAAAA.AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA';
5.4 In server.js, set the sender email in the emailFrom variable. Code: emailFrom = "aaa@aaa.com";
Now, to avoid falling into the "SPAM" folder there are two options:
a) Configure SendGrid to white list your sender email.
Go to https://app.sendgrid.com/settings/mail_settings > Address Whitelist > Edit > Add your email address (Eg: myemail@gmail.com) > Switch to ON
Note: For a less chance to fall in the SPAM folder, use an email address that you own and one of these methods to validate it.
b) Put any email address in the emailFrom
variable and add it to the white list in the receiver email client.
5.5 In server.js, set the emailsToAlert array. Code: emailsToAlert = ["emailOneToSend@theAlert.com", "emailTwoToSend@theAlert.com"];
