Flinks provides multiple testing environments so you can develop, test, and validate your integration before going live.
Testing levels
| Environment | Purpose | Real FI connections | Credentials |
|---|
| Sandbox (Dashboard) | Explore the Dashboard with sample data | No | Found in Dashboard Settings > Environments |
| Toolbox | Full API sandbox with dummy data from Flinks Capital | No | Shared public credentials (below) |
| Production | Live environment with real financial institutions | Yes | Unique credentials from Flinks |
| Credential | Value |
|---|
| Instance | toolbox |
| API Base URL | https://toolbox-api.private.fin.ag |
| Iframe Base URL | https://toolbox-iframe.private.fin.ag |
| customerId | 43387ca6-0391-4c82-857d-70d95f087ecb |

Test user credentials
Use these credentials to log in to Flinks Capital in the Toolbox:
| Username | Password | Description |
|---|
Greatday | Everyday | Standard test account with MFA |
greatday_nomfa | Everyday | Test account without MFA |
These are shared public sandbox credentials for testing only. Never use production credentials in the Toolbox or vice versa.
Dashboard sandbox
The Flinks Dashboard includes its own sandbox environment with pre-populated sample data. This is useful for exploring the Dashboard interface without needing to make API calls.
To access sandbox credentials in the Dashboard:
- Navigate to Settings.
- Go to the Environments tab.
- Expand the Sandbox row to view your credentials.
Dashboard sandbox credentials are for exploring the Dashboard only. They will not work in API calls. Use the Toolbox credentials above for API testing.
Production environment
Your production environment uses a private instance with unique credentials provided by Flinks during onboarding.
| Component | Format |
|---|
| API Base URL | https://{yourcompany}-api.private.fin.ag |
| Iframe Base URL | https://{yourcompany}-iframe.private.fin.ag |
| customerId | Unique GUID provided by Flinks |
- Ensure all API calls and iframe URLs point to your production instance
- Verify your
redirectUrl domains are whitelisted
- Test with Flinks Capital in production at no cost before connecting real accounts
FDX end-to-end testing
If you are using the Flinks Outbound (Open Banking) product with FDX endpoints, follow this procedure to test the full flow:
- Prerequisites: Ensure you have your
client_id and client_secret from Flinks onboarding.
- Authorize: Call the
/api/v1/authorize endpoint to initiate an OAuth connection with a test Data Provider.
- Token exchange: Use the authorization code to obtain an
access_token via the /Token endpoint.
- Retrieve data: Call FDX endpoints (
/accounts, /transactions) with the access_token.
For details on each endpoint, see the Outbound API Reference.
