    Designing Reliable CPaaS Webhooks: Delivery Logs, Retries, and Testing on Devotel Orbit

    A receiver-side guide to building webhook integrations on Devotel Orbit: every event the platform emits, the delivery logs, event sources, and sinks behind it, the four receiver-side patterns that make at-least-once delivery safe (signature verification, idempotency, backoff-aware retries, dead-letter handling), a worked Node.js receiver handling message delivery events with the Orbit SDK, and the build-test loop that runs through the Webhook Tester before you ship.

    SMPP vs REST for high-volume SMS — a practical choice framework

    High-volume SMS senders must eventually decide whether traffic enters the platform as an SMPP bind or as REST API calls with webhooks. Both doors reach the same routing and receipts on Orbit — so the choice is about throughput, latency, and how much session machinery you want to operate. This framework gives you a decision tree, both paths with real anchors, a worked campaign with MPS numbers, a hybrid migration pattern, and a trade-off table.

    Webhook Retry Logic: Framework Retries vs Delivery-Guaranteed Retries, Compared

    A buyer's comparison of the two webhook retry architectures: application-framework retries (Sidekiq, Celery, BullMQ) that five-attempt a callback and forget it, versus delivery-guaranteed retries (Stripe-style, as implemented on Devotel Orbit) that retry for hours on an exponential schedule, land failures in a replayable dead-letter queue, and disable only proven-dead endpoints. Scored row by row on schedule, deduplication, failure classification, observability, and what each model costs the receiver.

    Idempotency and safe retries: how the Devotel Orbit API avoids double-sends

    One POST per logical action, retried safely — how Orbit's Idempotency-Key contract, its 24-hour replay cache, the 409 body-mismatch guard, and wallet-level re-entry protection keep retries from becoming duplicate sends and double charges.
