Bank Transfers

Test bank transfers in the sandbox environment with simulated scenarios for ACH, Turbo, Transfiya, and Bre-B transfers.

In the sandbox environment, you can simulate successful and declined bank transfers. To develop your system correctly, keep in mind that two validations occur before the money is credited to the payee's account.

  1. To simulate ACH or Turbo cases, please set the corresponding value option in the routing field. 2. The simulation are evaluating the field payee.document_number.

ACH

These cases are available to simulate for ACH:

Origin bank validations

The first validation is done by our bank partner to ensure you have enough balance, including the GMF tax, and that you haven't exceeded the origin account's transactional limits (any admin user can adjust these limits directly in the user interface). Origin bank declinations in production are usually informed in less than 10 minutes through a webhook.

Test case: payee.document_number starts with 888 and ends with 000 (e.g., 88814235000)

Destination bank validations

The second validation is performed by the destination bank to check the account information and status. In production, these declinations take up to three ACH cycles, or around 12 working hours, to be received. In the sandbox, these are simulated in 2 minutes.

Test case: payee.document_number starts with 999 and ends with 000 (e.g., 99914235000)

Successful ACH bank transfer

The transfer should be approved.

Test case: payee.document_number does not meet the criteria for any of the other test cases.


Turbo

These cases are available to simulate for Turbo:

ScenarioDescriptionTest case
Global limit exceededThe transfer exceeds the global limit allowed for the account.Starts with 777, ends with 000
Insufficient fundsThe origin account doesn't have sufficient funds to complete the transfer.Starts with 777, ends with 111 or starts with 111, ends with 000
Turbo not supportedThe destination bank doesn't support Turbo transfers (signer not found).Starts with 777, ends with 222
Transaction deadline exceededThe transfer was rejected by the destination bank due to timeout.Starts with 777, ends with 333 or starts with 100, ends with 001
Disabled accountThe destination account is disabled.Starts with 777, ends with 444
Successful Turbo transferThe transfer should be approved.Does not meet any other criteria

Transfiya

These cases are available to simulate for Transfiya:

ScenarioDescriptionTest case
Global limit exceededThe transfer exceeds the global limit allowed for the account.Starts with 555, ends with 000
Disabled accountThe destination account is disabled.Starts with 555, ends with 444
Insufficient fundsThe origin account doesn't have sufficient funds to complete the transfer.Starts with 555, ends with 111
Transaction deadline exceededThe transfer was rejected by the destination bank due to timeout.Starts with 555, ends with 222
Transaction not completedThe user rejected or didn't complete the transaction through Transfiya.Starts with 555, ends with 333
Successful Transfiya transferThe transfer should be approved.Does not meet any other criteria

"global_limit_exceeded" is the only case that allows routing simulation with a permitted error for fallbacks.


CoopCentral Bre-B

CoopCentral Bre-B provides instant transfers through the Bre-B network. The sandbox allows you to simulate different scenarios using specific patterns in the Bre-B key (for key lookups) and description field (for transaction operations).

Bre-B Transfer Process

A Bre-B transfer follows a three-step process:

  1. Key Lookup: First, the system validates the Bre-B key and retrieves the associated account information from the network.
  2. Transaction Initiation: Once the key is validated, the transfer is initiated with the destination participant.
  3. Status Verification: Finally, the transaction status is checked to confirm whether it was completed successfully or failed.

The simulation sections below correspond to each of these steps, allowing you to test different scenarios at each stage of the transfer process.

Identity Validation

For successful Bre-B transfers in sandbox, when sending identity document information, you must use:

  • document_type: CC
  • document_number: 12345678

Important: If you send document identity information and it differs from these values, the transfer will generate errors. You can also choose not to send the document identity information to skip this validation.

Bre-B Key Lookup Simulation

These cases are available to simulate Bre-B key lookup by using specific Bre-B key patterns:

ScenarioDescriptionTest case
Key not foundThe Bre-B key doesn't exist in the network.Key contains key_not_found
Participant unavailableThe destination participant/bank is temporarily unavailable.Key starts with key_unavailable
Key blocked or inactiveThe Bre-B key is blocked or inactive in the network.Key contains key_blocked
TimeoutThe key lookup request timed out.Key contains key_timeout
Successful lookupThe Bre-B key lookup should succeed and return account information.Key doesn't match any error pattern

Bre-B Transaction Initiation Simulation

These cases are available to simulate Bre-B transaction initiation by using specific description patterns:

ScenarioDescriptionTest case
TimeoutThe transaction initiation request timed out.Description contains tx_timeout
Disabled accountThe destination account is disabled.Description contains tx_disabled
Invalid Bre-B keyThe provided Bre-B key is invalid.Description contains tx_invalid_key
Daily amount limit exceededThe transfer exceeds the daily amount limit.Description contains tx_limit_daily_amount
Daily count limit exceededThe account has exceeded the daily transaction count limit.Description contains tx_limit_daily_count
Fraud detectedThe transaction was flagged as fraudulent.Description contains tx_fraud
Insufficient fundsThe origin account doesn't have sufficient funds.Description contains tx_insufficient
Monthly amount limit exceededThe transfer exceeds the monthly amount limit.Description contains tx_limit_monthly_amount
Monthly count limit exceededThe account has exceeded the monthly transaction count limit.Description contains tx_limit_monthly_count
Invalid accountThe destination account information is invalid.Description contains tx_invalid_account
Account blockedThe destination account is blocked.Description contains tx_blocked
Unknown errorAn unknown error occurred during processing.Description contains tx_error
Successful initiationThe transaction should be initiated successfully.Description doesn't match any error pattern

Bre-B Transaction Status Simulation

These cases are available to simulate Bre-B transaction status checks by using specific Bre-B key patterns:

The transaction status simulation uses the same Bre-B key that was used during the key lookup step. The system validates the pattern of the Bre-B key to determine which status to return.

ScenarioDescriptionTest caseStatus code
Transaction not foundThe transaction ID doesn't exist.Key contains status_not_found-
TimeoutThe status check request timed out.Key contains status_timeout-
Participant unavailableThe participant is unavailable for status checks.Key contains status_unavailable-
Failed transactionThe transaction has failed.Key contains status_failed91
Pending transactionThe transaction is still pending.Key contains status_pending-
Successful transactionThe transaction has completed successfully.Key doesn't match any error pattern00
