Get Sandbox Access
The NextAPI sandbox lets you test the full API without processing real transactions or moving real money. All features available in production are available in sandbox.
How the Sandbox Works
- Same API, same endpoints:
https://api.partners.nextpay.world/v2/ - Same authentication: Basic Auth with your sandbox Client ID and Client Secret
- No real money moves: Transactions are simulated end-to-end
- Full webhook support: Receive webhooks for sandbox events
Request Sandbox Credentials
To get started with sandbox access:
- Contact the NextPay partnerships team at [email protected]
- Provide your company name, use case, and expected volume
- Receive your Client ID and Client Secret within 1 business day
- Start building immediately
What You'll Receive
| Credential | Description |
|---|---|
| Client ID | Your unique identifier for API authentication |
| Client Secret | Your secret key for API authentication |
| Merchant ID | Pre-created test merchant for immediate use |
| Account ID | Pre-funded test account with sandbox PHP balance |
Quick Start
Once you have your credentials, make your first API call:
curl -X GET "https://api.partners.nextpay.world/v2/merchants" \
-H "Content-Type: application/json" \
-u "YOUR_CLIENT_ID:YOUR_CLIENT_SECRET"
See the Your First API Call tutorial for a complete walkthrough.
Sandbox Limitations
| Limitation | Details |
|---|---|
| Payouts | Simulated only — no real funds reach bank accounts |
| Payment channels | Some channels have limited simulation support |
| Data retention | Sandbox data is periodically reset |
Moving to Production
When you're ready to go live:
- Complete partner onboarding — submit your business details through the NextPay partnerships team
- Receive production credentials — a new Client ID and Client Secret scoped for live transactions
- Update your credentials — no endpoint changes needed; the API URL stays the same
- Go live — start processing real transactions immediately
