How do I get sandbox API credentials?

The short answer

client_id

(6-digit number) and

client_secret

are issued automatically to your dashboard. No sales call required.

What you get

Try it yourself

Free sandbox. Real Tier-1 carriers. 60 seconds from signup to credentials.

A dedicated sandbox
```
client_id
```
and
```
client_secret
```
50 EUR of sandbox credit pre-loaded
Full access to the eSIM provisioning endpoints against test carriers
No expiry as long as you stay active (credentials are reclaimed after 30 days of zero API activity)

First call

Use your credentials to mint an OAuth2 token:

bash
curl -X POST https://connect.test.firsty.app/api/v3/oauth/token \
  -d "grant_type=client_credentials" \
  -d "client_id=123456" \
  -d "client_secret=YOUR_SECRET"

The token is valid for 1 hour. Cache it, do not re-request on every call.

Going to production

Production credentials are issued after a short qualification call. Use the "Request production access" link in your dashboard.
