Sandbox - Senderz API

Overview

All endpoints are available in sandbox mode using sz_test_ API keys. Sandbox mirrors production behaviour with simulated external systems.

Messaging sandbox

Messages are validated and logged but not dispatched to any carrier.
Delivery report callbacks are simulated: delivered after 2 seconds.
To test failure flows, send to a number ending in 0000 (e.g. +61400000000). These messages return failed status.
You are not charged for sandbox messages.

curl -X POST https://api.senderz.ai/v1/messaging/messages \
  -H "Authorization: Bearer sz_test_xxxxxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{
    "to": "+61412345678",
    "sender_id": "TestBrand",
    "body": "Sandbox test: your order SYD-12345 has been dispatched.",
    "market": "AU"
  }'

Sender ID sandbox

Registrations are validated against market rules but not submitted to any register.
Status transitions are simulated on a 5-minute cycle: pending_review > pending_register > registered.
To test rejection flows, use a match_value starting with REJECT (e.g. REJECT Test Pty Ltd). These SIDs move to rejected status with a simulated rejection reason.

Brand sandbox

Verification is simulated. Brands with valid identifiers are auto-verified within 10 seconds.
ABNs starting with 99 are auto-rejected for testing error flows.
