}Provider sandbox on this deployment. Our backend targets the bank provider’s sandbox: bank details are test details, no real transfer settles, and settlement lands on a testnet (read
network from GET /v1/config). Known limits: only the EUR/IBAN rail is wired for the simulated pay-in, and identity checks run on test-mode applicants. Every response says which environment answered in its environment field.Authorizations
Your API key, issued by us and shown once at creation.
Body
application/json
One-time authorization code from the identity provider's button in your UI.
Minimum string length:
1The two fields the identity provider does not share and the bank provider requires.

Response
Onboarded, or consent still needed.
- Option 1
- Option 2
Which environment answered. sandbox: at least one money upstream is the provider's sandbox - no real money moves there, and the card corridor is the sandbox's asset (read GET /v1/config), not the documented production one. production: every configured upstream is real. Derived from the configured upstream hosts at boot, never a flag.
Available options:
sandbox, production Example:
"sandbox"
Allowed value:
"onboarded"The user's account id at the bank provider.
The linked wallet id (the settlement destination).
KYC status right after creation.
Example:
"pending"
