Everything you need to publish your first message.

1. Create an application

Issue an app ID from the console. Each app has its own key pair and rate limits.

2. Connect over gRPC

The API listens on port 443 and requires TLS with ALPN h2. Any HTTP/2 capable gRPC client works.

3. Publish

Call Publish with a channel and payload. Delivery receipts arrive on the same stream.
