...bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we respect rate li...
