00 / HOW IT WORKS

From send to delivered, with retries.

STEP 01

You send

One API call. Three lines. SDKs or raw curl.

POST /applications/{applicationId}/messages
STEP 02

We sign

Each payload signed HMAC-SHA256. Timestamped. Replay-safe.

webhook-signature: v1,g0hM9SsE…
STEP 03

We deliver — and retry

Up to 20 attempts over 5 days. Exponential backoff. Manual replay.

01 / PRODUCT

Built for webhooks
in production.

No email, no SMS, no "all-in-one platform." Just webhooks. Done right. With the guarantees you expect from a trusted third party.

01

HMAC signature

SHA-256, webhook-signature header, replay protection via timestamp.

02

Exponential retries

Up to 20 attempts over 5 days. Backoff configurable per endpoint. Dead-letter queue visible.

03

Manual replay

Replay one event, one endpoint, or an entire batch from the Portal. Idempotency preserved.

04

Detailed logs

Payload, headers, response, timing. Filterable, exportable, inspectable. Everything traceable.

05

Built-in rate limiting

Per-organization quotas, per-endpoint throttling, upstream DDoS protection. No bad surprises.

06

SDKs & examples

Node, PHP, Python, Go. Signature verification examples copiable in one line. Open docs.

02 / TRUST STACK

03 / SOVEREIGNTY

Hosted in France.
Period.

Most webhook platforms store your events in the United States, behind opaque subprocessors. We take the opposite approach.

06 / FAQ

Questions we
get asked.

Can I try it for free? +
Yes. The Seed plan is free forever up to 10,000 messages per month. No credit card required. You upgrade to Startup only when you exceed the quota or need more endpoints.
How do retries work? +
Up to 20 attempts spread over 5 days, with exponential backoff. You can adjust the strategy per endpoint (max count, delays, conditions). After exhaustion, the message moves to the dead-letter queue — visible and manually replayable.
Where is my data stored? +
In France, on Scaleway, Paris region. Your event data never leaves the EU. Billing is handled by Stripe (listed in our DPA) and never touches your webhook payloads.
What if I exceed the quota? +
We alert you by email at 80% consumption. If you exceed, messages are processed normally (we never cut your service) and you are billed at the overage rate. No bad surprises.
