webhook-to-pubsub

Handles incoming requests and publishes their data up to Google PubSub. The payload must be encrypted before sent to ensure the data isn't spoofed.

Use AES128 encryption with a shared key and a random IV. When sent, the IV should be prepended to the payload. The result should be url-safe base64 (- instead of + and _ instead of /) and sent as the p over the query string.

Config should be loaded via environment variables:

• HTTP_PORT - the port that the service is exposed on
• KEY - the encryption key
• PUBSUB_CREDS - json containing ProjectID and TopicName

Example

GET /fulfillment/vanity-string?p=[iv+payload] HTTP/1.1
content-length: 0
