SkyWatch EarthCache Slack Webhook CDK Template

This is an AWS CDK template for creating a service that receives outgoing subscription messages from SkyWatch EarthCache and sends block-formatted messages to a Slack incoming webhook app.

Setup and Usage

1. Create a Slack webhook app. You will create a Webhook URL and install the app to a channel in your Slack workspace.
2. Set environment variables like those found in .envrc_template:

• SKYWATCH_API_KEY = your SkyWatch EarthCache API key
• SLACK_WEBHOOK_URL = Slack webhook URL created above, starting with /services/...

3. Synth (cdk synth) and deploy (cdk deploy) the CDK stack within this repo, which creates an API Gateway and a Lambda Function in your authenticated AWS account.
4. Once the stack has been created, use the output API Gateway URL + Lambda Function name as the callback_uri when creating a subscription to SkyWatch EarthCache.
