Step-by-step implementation guides for common integration patterns, production hardening, and debugging.
Correlation IDs & Tracing (Connect Your App Logs to Delivery Runs)
Add correlation IDs and tracing to webhook consumers so you can match delivery runs to application logs; implement propagation, structured logs, and triage queries.
Delivery Log Search & Filters
Find the single delivery run that matters using filters: event key, status, time window, and endpoint. Practical queries and interpretation to speed root-cause analysis.
Monitoring & Alerting for Webhook Deliveries
Create actionable webhook alerts for failure rates, sustained retries, latency spikes, and signature failures, with runbooks and thresholds to reduce noise and speed response.
Replay Webhook Deliveries from the Delivery Log (Safely)
Replay webhook deliveries safely from your delivery log: preserve dedupe keys, use idempotent handlers, validate fixes, and replay carefully to avoid duplicate side effects.
Verify Webhook Signatures Securely: Common Pitfalls
Learn how to verify SendPromptly webhook signatures in Laravel using raw request bodies, HMAC-SHA256, timestamps, and constant-time comparison—plus the top mismatch failure modes
Build a Webhook DLQ in Laravel (Replay Failed Events Safely)
Store every webhook in an inbox table, process async, and move poison events to a dead-letter queue so you can replay safely without duplicate side effects.
Debug Webhooks with Delivery Logs (Message Log Workflow)
A practical workflow to debug missing or failed webhooks using Message Log: confirm attempts, status codes, timeouts, retries, and where your endpoint breaks.
Webhook Retries: Backoff & Jitter
Understand webhook retry behavior with backoff and jitter, how to use 2xx/4xx/5xx correctly, and how to keep your endpoint idempotent.
Idempotent Webhook Handling in Laravel
Prevent duplicate side effects from webhook retries with proven idempotency patterns: inbox table + unique keys, Redis SETNX, and replay-safe processing in Laravel.
Webhook Retries: Headers and Correct Endpoint Responses
Learn how retries really behave (even without special headers), how to use 2xx/4xx/5xx/429 correctly, and how to avoid duplicate side effects with retry-safe Laravel handlers.
Email Provider Webhooks: SendGrid, Mailgun & SES
Implement SendGrid, Mailgun, and AWS SES/SNS event webhooks with signature verification, fast ACK patterns, idempotent processing, and canonical normalization into SendPromptly.
AWS SES Notifications via SNS: Bounces & Deliveries
Configure AWS SES to publish bounces, complaints, and deliveries to SNS, subscribe your Laravel endpoint, parse SES payloads, and forward normalized events into SendPromptly.
Best Practices for Webhook Observability
Monitoring and observability patterns for webhooks: logging, tracing, alerting, and metrics to detect failures, latency, and retry backlogs before they impact users.
Handling Out-of-Order Webhook Events
Design consumers that tolerate out-of-order webhook events: use idempotency, versioned state, reorder windows, and conflict-proof processing patterns to preserve correct state.
Mailgun Webhooks in Laravel
Build a Laravel endpoint for Mailgun webhooks: parse form-encoded and JSON payloads, enqueue processing, normalize events, and forward them into SendPromptly.
Rotate Webhook Signing Secrets Without Downtime
Rotate webhook signing secrets without downtime using a dual-secret window, safe comparisons, middleware checks, and a concise cutover runbook to keep deliveries uninterrupted.
Scale Your Webhook Consumer: Ack Fast & Apply Backpressure
Handle webhook bursts without duplicate side effects using ack-fast queueing, concurrency controls, 429 Retry-After responses, and retry-aware backoff.
SendGrid Event Webhook in Laravel (Receive, Queue, Normalize)
Implement a reliable SendGrid event webhook in Laravel: receive batched JSON events, ACK fast, dedupe, normalize, and forward canonical events into SendPromptly.
Test Webhooks Locally: Tunnels, Signing & Message Log
A reliable local webhook loop: expose localhost with a tunnel, verify signatures using raw body, trigger real deliveries via SendPromptly, and debug outcomes in Message Log.
Verify AWS SNS Signatures in PHP
Validate AWS SNS message signatures in PHP: enforce trusted SigningCertURL, verify signature versions, pin TopicArn, and safely handle SubscriptionConfirmation in Laravel.
Verify Mailgun Webhook Signatures in Laravel
Verify Mailgun webhook authenticity in Laravel with HMAC-SHA256, timestamp checks, token replay protection, and middleware test steps.
Verify SendGrid Signed Event Webhooks in Laravel
Secure your SendGrid Event Webhook by verifying the ECDSA signature using the `X-Twilio-Email-Event-Webhook-Signature` + timestamp and the raw request bytes.
Webhook Observability: Correlation IDs & Structured Logs
Add correlation IDs and structured logs to webhook consumers so you can triangulate retries and failures with SendPromptly delivery runs; covers propagation and safe logging.
Webhook Payload Design: Thin vs Fat Payloads
Choose between thin and fat webhook payloads: when to send identifiers vs actionable snapshots, schema versioning, and migration patterns to avoid breaking consumers.
Webhook Retry Strategies
Implement webhook retry strategies with exponential backoff, jitter, and idempotency to handle transient failures while avoiding retry storms and duplicate side effects.
Webhook Security Checklist (Ship It Without Getting Burned)
A practical security checklist for webhook endpoints: signature verification, replay protection, rate limiting, payload validation, idempotency, DLQ, and audit-friendly logging.
Webhook Signature Verification Cookbook
A cookbook of signature verification patterns for Laravel/PHP: raw body, HMAC-SHA256, constant-time comparisons, timestamp windows, and local test vectors.
Webhook Signing Methods Compared: HMAC vs Public-Key
A practical comparison of webhook signing approaches across popular APIs (Stripe, Paddle, SendGrid, Mailgun) and how to design a single verification layer in Laravel.
