postmarkapp.com:server

Postmark sandbox and mock API

Postmark makes sending and receiving email incredibly easy. Writes persist, data moves on a schedule and every change can fire a signed webhook.

example request

curl https://your-postmarkapp-server.slurry.io/bounces \
  -H "Authorization: Bearer slurry_sim_..."

Your simulation gets its own hostname, key and IP allow-list. Built from API version 1.0.0.

What gets simulated

Collections, relationships and state machines are worked out from the spec when you start the simulation.

State. Creates, updates and deletes persist and show up in later reads.
Behaviour. Records move through their states on a schedule you control, and you can fast-forward up to 30 days.
Webhooks. Every change emits a signed, retried event.
Failure. Per-endpoint errors, latency and chaos rules, on demand.
