Ploy Webhook Ingest API
The only public HTTP endpoint Ploy documents. An authenticated inbound ingest endpoint that accepts any well-formed JSON object (up to 1 MB) from an external system — Clay, Stripe, Zapier, or a custom backend — stores it verbatim with its timestamp and source endpoint, and optionally runs a Ploybook with the payload injected as prompt context. Each endpoint has its own bearer key, shown once at creation. POST only; 202 on acceptance; documented 400/401/403/404/413/415/429 failures. Ploy does not retry inbound events and publishes no idempotency key, so senders must retry on 5xx and 429 with backoff and dedupe on their own side.
