Slack

You can post all errors to a Slack channel. You'll need to create a webhook in Slack. Then use the following settings:

• ckanext.push_errors.url=https://hooks.slack.com/services/T02XXXXXX/B061XXXXXX/GASXXXxxxXXXxxx (something like this).
• ckanext.push_errors.method=POST
• ckanext.push_errors.headers={}
• ckanext.push_errors.data={"text": "{message}", "username": "CKAN PUSH ERRORS", "icon_url": "https://github.com/unckan/ckanext-push-errors/raw/main/icons/server-error.png"}: Slack requires the text field to be present.

To create a webhook in Slack:

• Create a new channel if you want to send this notifications to a new channel. If not, you can use any existing channel.
• Good look with this incredible complex way to create a webhook: https://api.slack.com/messaging/webhooks
• Probably going to https://api.slack.com/apps/YOUR-APP-ID/incoming-webhooks URL will help you.
