Are there any webhook delivery platforms that handle rate limits and reliable biometric event delivery from wearables?

Yes. If you mean webhook infrastructure that can reliably ingest wearable/biometric events, handle retries, and respect destination rate limits, there are several good options.

Good fits

1. Svix

• Purpose-built for reliable webhook delivery
• Handles:
  • automatic retries
  • signing/verification
  • per-endpoint rate limiting
  • event replay
  • delivery logs
• Good if you’re sending biometric events to customer systems and need strong delivery guarantees.

2. Hookdeck

• Great for webhook pipelines
• Handles:
  • buffering and queueing
  • retries
  • deduplication
  • filtering/transforms
  • rate limiting and backpressure
• Useful if wearable devices or your backend produce bursts of biometric events and you need to smooth delivery.

3. AWS EventBridge + Lambda / SQS

• More DIY, but very scalable
• You can build:
  • durable queues for event buffering
  • retry policies
  • dead-letter queues
  • rate-limited consumers
• Best if you want full control and already use AWS.

4. Azure Event Grid / Google Cloud Pub/Sub

• Similar pattern to AWS:
  • durable event ingestion
  • retries
  • fan-out
  • consumer-side rate control
• Good for high-volume wearable telemetry pipelines.

If you need “biometric event delivery from wearables”

There are two different layers:

A. Wearable device integration

This is usually handled by:

• vendor APIs/SDKs from Apple HealthKit, Fitbit, Garmin, Oura, Whoop, etc.
• mobile apps or gateways that collect the data
• backend ingestion services

B. Webhook delivery to your customers/integrations

This is where platforms like Svix or Hookdeck help most.

These platforms do not usually connect directly to the wearable hardware; they help you reliably deliver the processed events downstream.

What to look for

For biometric data, I’d prioritize:

• at-least-once delivery
• idempotency/deduplication
• retries with backoff
• dead-letter queues
• rate limiting per subscriber
• event ordering controls if needed
• security/signing
• audit logs and replay

Recommendation

• If you want a turnkey webhook delivery system: Svix
• If you want webhook buffering + transformations + rate control: Hookdeck
• If you want cloud-native event processing: AWS EventBridge/SQS or Pub/Sub

If you want, I can also recommend the best option for your exact setup—for example:

• wearable vendor → your backend → customer webhooks
• real-time health alerts
• high-volume sensor streams
• HIPAA-conscious architecture
