Returns the current mock testing configuration for the sandbox environment. Use specific transaction amounts to simulate different outcomes.

Mock testing is only available in the sandbox environment.

Mock Rules

The 10.01, 10.02, and 10.03 amounts have been retired. They collided with genuine small-value sandbox orders, so a real 10.01 transaction was silently completed by the mock path. If your integration is pinned to any of those amounts, move it to the 1000.0x band below.

On-Ramp Transactions

Use fiatAmount to trigger specific behaviors:

Fiat Amount	Expected Status	Description
`1000.01`	`COMPLETED`	OTC transaction completes successfully
`1000.02`	`CANCELLED` (NAME_VERIFICATION_FAILED)	OTC bank beneficiary is not the KYC’d user

Off-Ramp Transactions

Use cryptoAmount to trigger specific behaviors:

Crypto Amount	Expected Status	Description
`1000.01`	`COMPLETED`	OTC transaction completes successfully
`1000.02`	`CANCELLED` (NAME_VERIFICATION_FAILED)	OTC bank beneficiary is not a KYC’d user
`1000.03`	`CRYPTO_NOT_RECEIVED`	OTC failure due to no crypto transfer

Cross-Ramp Transactions

Use sourceAmount to trigger specific behaviors:

Source Amount	Expected Status	Description
`2000.01`	`COMPLETED`	Walks the full lifecycle: `PENDING_FUNDS` → `FUNDS_RECEIVED` → `IN_PROGRESS` → `AWAITING_FUND_TRANSFER` → `COMPLETED`
`2000.02`	`CANCELLED` (NAME_VERIFICATION_FAILED)	Bank beneficiary is not a KYC’d user
`2000.03`	`AWAITING_FUND_TRANSFER`	Halts at `AWAITING_FUND_TRANSFER` so the payout leg can be exercised

For example, to create a cross-ramp that halts at AWAITING_FUND_TRANSFER:

{
  "userId": "12a121ad-cbea-4ec4-9e0a-5c861e528bba",
  "sourceAmount": 2000.03,
  "sourceCurrency": "MXN",
  "targetCurrency": "USD",
  "targetBankAccountId": "0b7e1c9f-3a4d-4f21-9a2e-5d8c6b1f4e30"
}

Cross-ramp uses its own 2000.0x band rather than reusing the on/off-ramp amounts. The internal on-ramp leg of a cross-ramp inherits the parent’s source amount, so a cross-ramp at 1000.01 would trigger the on-ramp rule underneath the cross-ramp one.

Cross-ramp specifics:

Only sourceAmount triggers a mock. On the targetAmount path the source amount is fee-derived and will never match a magic value.
If you create the transaction from a quoteId, the quote itself must have been created with sourceAmount set to one of the magic values.
The transaction advances through the real state machine, so every cross-ramp webhook fires in order — CREATED_CROSS_RAMP, FUNDS_RECEIVED_CROSS_RAMP, STARTED_PROCESSING_CROSS_RAMP, AWAITING_FUND_TRANSFER_CROSS_RAMP, and COMPLETED_CROSS_RAMP (or CANCELLED_CROSS_RAMP for 2000.02).

Important Notes

You must use the exact amounts specified above (1000.01, 1000.02, 1000.03, 2000.01, 2000.02, 2000.03).
Transaction amount limits are not enforced for mock amounts. All other validation rules still apply (KYC status, etc.).
The system automatically handles state transitions to reach the target status.
