/issue_sila

Initiates an ACH Debit transaction from an external source and issues those funds into a Sila wallet.

The /issue_sila endpoint starts the ACH Debit transaction of an end user's linked bank account (or other payment instrument); once that transaction has officially settled, the funds will be issued to the end user's Sila wallet.

🚧

To be deprecated

/issue, /redeem, and /transfer will, in the long-term, be deprecated in favor of our /transact endpoint. We have no current date set for that deprecation, and we will continue supporting existing use of these endpoints until all customers can implement /transact.

Please implement /transact for all transaction types.

📘

Transaction Amount in Decimal Units

Please be aware that the amount value for this endpoint is in decimal units.

EX:

Transaction for $10 USD

/issue amount value = 1000

For ECDSA, be aware that unless specified otherwise, the wallet to which funds are issued is the one used to generate the usersignature header.

For OAuth2, you will need to specify the source_id and destination_id. Please see key chart below for more details.

👍

/issue Timing

In SANDBOX, issuing funds can take up to five minutes.

In PROD, issuing funds will take a few business days, depending on when the request is sent. Read more about ACH timing here.

When issuing funds from a debit card (Checkout.com integration), funds are available almost immediately.

You can check the status of a transaction using the /get_transactions endpoint. You can also use webhooks to receive a notification when a transaction status is updated.

📘

Note for Debit Card issue transactions

As of February 2024, we have added support for Visa AFT. See more here.

Requests

Authorization / Authentication

Apps using Access Token Authorization

Use a valid access token in an Authorization: Bearer request header.

See Authenticating with an Access Token for more details.

Apps using ECDSA Authentication

Both authsignature and usersignature headers are required for this request. The usersignature header should be generated with a keypair registered to the user (either registered from the /register endpoint or the /register_wallet endpoint).

See the section on ECDSA Authentication for more detail about ECDSA signature generation.

Note - We recently renamed the field auth_handle to app_handle. For backward compatibility, auth_handle is still valid but has been removed from our documentation.

👍

/issue_sila - The Unhappy Path

Standard and Same Day ACH: In the sandbox only, you can simulate an ACH return by sending any amount ending in 420, like 1420 ($14.20), 78420 ($784.20), or 420 ($4.20). This will always simulate an ACH return of type R01-Insufficient Funds

👍

Sandbox business UUID

For the purposes of testing /issue_sila in the Sandbox environment, you can use the business_uuid: a9f38290-ce34-42db-95ab-630ebba6084a.

The account_name field is the name of the handle's linked account from which to debit the equivalent dollar amount. DO NOT include if you are using your bank account as the source_id.

The source_id field is the payment method ID that is the source of funds. Please see key chart below for more details.

The destination_id field is the payment method ID that is the destination of the funds. Please see key chart below for more details.

The optional descriptor field is a 100-character field used to describe the transaction on the end-user’s bank statement.

The optional business_uuid field identifies a business which has an approved "ACH name."

The optional processing_type field allows specifying either "STANDARD_ACH"to use the standard ACH schedule "SAME_DAY_ACH" to use the Same Day ACH schedule.


For ECDSA, there are several valid combinations of optional parameters (account_name, source_id, destination_id) that can be used to identify the source and destination that will be used for the transaction. Below is that list:

  • account_name - for this, the source will be the linked bank account with that account name, and the destination will be the end users wallet as inferred from the user signature.
  • card_name - for this, the source will be the linked debit card with that card name, and the destination will be the end users wallet as inferred from the user signature.
  • source_id, destination_id - for this, the source will explicitly be the payment method specified with source_id, and the destination will explicitly be the payment method specified with the destination_id.

For OAuth2, source_id and destination_id are required.

📘

Descriptors

Currently only the first 10 characters of the 100-character descriptor field will appear on the customer's statement. Default values are Debit or Credit and do not carry a surcharge. The use of a descriptor will incur an additional fee per transaction

📘

ACH name

This is a 16 character field that appears on the end-user’s bank statement and reflects the company name responsible for the transaction. There is an additional application fee and process to approve the use of the company name.

KeyTypeDescription
headerJSON objectRequired. Requires these keys in JSON format: created, app_handle, user_handle. See the /check_handle endpoint for the complete list of fields in this object.
amountIntegerRequired. Min Length 1, Max digits 35 Example: 1000
Max value: 10000000
Please contact Sila to increase.
account_nameStringOptional. Max Length 40. Name of the linked account to debit from that is the source of funds.

DO NOT include if you are using your bank account as the source_id.

Example: default
descriptorStringOptional. Max Length 100
Note that only the first 10 characters show on the resulting bank statement. Example: transaction descriptor
business_uuidStringOptional. UUID of a business with an approved ACH name.
The format should be a UUID string.
Example: 5167160d-9d12-4fa8-a8cd-302507782de0
processing_typeStringOptional. Choice field.
Examples: STANDARD_ACH, SAME_DAY_ACH, INSTANT_SETTLEMENT, CARD_CKO
source_idStringFor ECDSA:
Optional. Payment method ID that is the source of funds. This can be used as an alternative to account_name. Valid values for this field can be viewed using /get_payment_methods and looking for the **_id value. Example: bank_account_id = 5167160d-9d12-4fa8-a8cd-302507782de0.

For OAuth2:
Optional. ID that is the source of funds. Valid values for this field can be viewed using /get_payment_methods and looking for the bank_account_id value or card_id value.
destination_idStringFor ECDSA:
Optional. Payment method ID that is the destination of the funds. If not provided, the wallet in the usersignature of the header will be credited. Valid values for this field can be viewed using /get_payment_methods and looking for the **_id value. Example: blockchain_address_id = 5167160d-9d12-4fa8-a8cd-302507782de0.

For OAuth2:
Optional. Valid values for this field can be viewed using /get_payment_methods, which will return a "ledger_account_id" that will be used as the destination_id.
transaction_idempotency_idStringOptional. UUID to uniquely identify the transaction to make it idempotent. If transaction is submitted multiple times with the same transaction_idempotency_id it will only be processed once.
card_nameStringOptional. Max Length 40

Name of the linked card to debit from that is the source of funds. Example: default_card
