Quickstart
Ten minutes, one terminal. You'll accept an invite, mint an API key, create your first subscriber, start a subscription, and receive your first webhook. Everything runs against the sandbox.
Prerequisites
- An invite from a Helium MVNE super-admin (check your inbox).
curland a shell that supports$(uuidgen).
1. Accept the invite
Click the link in the invite email. You'll land on the Helium MVNE admin dashboard and be prompted to set a password. Once you're signed in, you're an operator admin on your operator's sandbox.
2. Create a sandbox API key
In the dashboard, open Developers → API keys and click
Create key. Choose Restricted for this walkthrough and grant
subscribers:write, subscriptions:write, and webhooks:read.
Copy the key — it starts with rk_sandbox_. You'll see it exactly
once.
export MVNE_KEY=rk_sandbox_...
export MVNE_URL=https://api.mvne.example
3. Create a subscriber
The response contains a public_id that starts with sub_.
4. Register a webhook endpoint
Point the platform at an endpoint you control. For the quickstart, webhook.site works fine.
Webhook endpoints are registered from the dashboard, not the
API — open Settings → Webhook endpoints in your operator
workspace, paste the URL, select subscription.created under
enabled events, and save. Copy the signing secret the dashboard
shows once (it's not retrievable later), and stash it in your
backend's secret store for signature verification.
See Webhooks for HMAC code samples and the full lifecycle.
5. Start a subscription
curl $MVNE_URL/v1/subscriptions \
-H "Authorization: Bearer $MVNE_KEY" \
-H "Idempotency-Key: $(uuidgen)" \
-d subscriber_id=sub_... \
-d plan_id=plan_sandbox_basic
Within a few seconds, webhook.site shows a subscription.created
event. That's your platform loop end-to-end.
Next steps
- Authentication — key tiers and rotation.
- Webhooks — verify signatures, handle retries.
- SIMs lifecycle — provision your first SIM and walk it through activation.
- Testing in sandbox — drive state transitions without touching a real carrier.
