A Plug for handling BoldSign webhooks.

This plug verifies the webhook signature and dispatches the event to a handler.

Usage

In your endpoint.ex, before Plug.Parsers:

plug Boldsign.WebhookPlug,
  at: "/webhook/boldsign",
  handler: MyApp.BoldsignHandler,
  secret: "your_webhook_secret"

The secret option can also be a zero-arity function for runtime resolution:

plug Boldsign.WebhookPlug,
  at: "/webhook/boldsign",
  handler: MyApp.BoldsignHandler,
  secret: fn -> System.fetch_env!("BOLDSIGN_WEBHOOK_SECRET") end

Your handler should implement the Boldsign.Webhook.Handler behavior.
