Setup a Slack Webhook for Sending Messages From Applications
Slack is amazing and I cant live without it.
We can also use custom webhook integrations to allow applications to notify us via slack in response of events.
What we will be doing
We will be configuring a custom slack webhook integration and test out the api to show you how easy it is to use it to inform us via slack, whenever something is happening.
Configuration
Head over to:
- https://{your-team}.slack.com/apps/manage/custom-integrations
curl -XPOST -d 'payload={"channel": "#system_events", "username": "My-WebhookBot", "text": "This is posted to #general and comes from a bot named <https://alert-system.com/alerts/1234|webhookbot> for details!", "icon_emoji": ":borat:"}' https://hooks.slack.com/services/xx/xx/xx
Will result in:
Message Attachment, Error:
1
curl -XPOST -d 'payload={"channel": "#system_events", "username": "My-WebhookBot", "text": "*Incoming Alert!*", "icon_emoji": ":borat:", "attachments":[{"fallback":"New open task [Urgent]: <http://url_to_task|Test out Slack message attachments>","pretext":"New open task [Urgent]: <http://url_to_task|Test out Slack message attachments>","color":"#D00000","fields":[{"title":"Notes","value":"This is much easier than I thought it would be.","short":false}]}]}}' https://hooks.slack.com/services/xx/xx/xx
Results in:
Message Attachment, OK:
1
curl -XPOST -d 'payload={"channel": "#system_events", "username": "My-WebhookBot", "text": "*Status Update:*", "icon_emoji": ":borat:", "attachments":[{"fallback":"New open task has been closed [OK]: <http://url_to_task|Test out Slack message attachments>","pretext":"Task has been closed [OK]: <http://url_to_task|Test out Slack message attachments>","color":"#28B463","fields":[{"title":"Notes","value":"The error has been resolved and the status is OK","short":false}]}]}}' https://hooks.slack.com/services/xx/xx/xx
