Environments

SatStacker Engine supports two environments:

Environment	Key prefix	Purpose
Sandbox	sse_test_	Integration testing and non-production validation
Production	sse_live_	Live partner traffic and real user trading

Both environments use the same base URL:

https://api.satstacker.app

The API key determines which environment your request uses.

Sandbox

Sandbox keys start with:

sse_test_

Use sandbox for:

• Initial integration work
• API contract testing
• Worker testing
• Execution polling and confirmation testing
• Billing/reconciliation validation

Sandbox executions do not represent real user trades unless your own system chooses to execute them against a live venue. Partners should keep sandbox workers isolated from production trading infrastructure.

Production

Production keys start with:

sse_live_

Use production only after:

• The sandbox flow has been tested end-to-end
• Your polling worker handles retries and idempotency correctly
• Your confirmation flow is stable
• Your team has received a production key from SatStacker

Production executions represent live Smart Timing instructions for real users.

Environment isolation

Sandbox and production data are isolated.

A sandbox key can only read and write sandbox records. A production key can only read and write production records.

This applies to:

• Partner users
• Plans
• Execution instructions
• Trade confirmations
• Billing reports

For example, if you create partner_user_id: "user_123" using a sandbox key, that user does not exist in production. Creating the same partner_user_id with a production key creates a separate production record.

Checking your environment

Call GET /partner/v1/me to confirm which environment your key is using:

curl https://api.satstacker.app/partner/v1/me \
  -H "Authorization: Bearer sse_test_YOUR_KEY_HERE"

Example response:

{
  "partner_slug": "your_partner_slug",
  "partner_name": "Your Partner Name",
  "status": "active",
  "environment": "test"
}

If you expected production but see "environment": "test", you are using a sandbox key.

Production cutover

To move from sandbox to production:

1. Complete sandbox testing.
2. Request a production key from SatStacker.
3. Deploy the sse_live_* key to your production environment.
4. Confirm GET /partner/v1/me returns "environment": "live".
5. Start production polling workers.

You do not need to change the base URL. Only the API key changes.
