Learn how to encrypt a DDS configuration to a payDistributionConfig
.
To start the direct deposit update process in Link you must initialize it with the payDistributionConfig
parameter set to an encrypted version of your DDS configuration.
The encryption is necessary to ensure bank account and card details are never exposed on the front-end. Full routing, account, and card numbers always appear encrypted on the end user's device.
To encrypt your DDS configuration make a POST
request to pay-distribution-configs/encrypt
with your DDS configuration in the payload.
The request returns an encrypted version of the DDS configuration that will look similar to:
{
"encrypted_config": "CiQAB/5lecrbJVrkdodwk4sgqacFNCiaH638IgDAHa8/peRjEEoShwIA8Gmka0Ea+JAa75M5HxfTckMklvPVvRxPYV3ND+YisxMhcHk6Fig0bwUUJiotuw/L5YkbHysTMPU6PSvXnHs19lNDZfVO6qpo44U6eMRdqO65HC864QEEi5n/u7QQT3DcG43RiVoRCnDiBlcdGIOPxth+gX6JgygigFHLEFhfOKWaQdyOmHDuf9cZNxp3M26IBEEtgmznl4oSm1qFt6ZzMcvdvKd2nOMS5co3Nc4f6F67GlnCRHEjzszBUnkgpsj60KFKggQ0e/CRQWi5pM/wa7UCb80LAKKm8Tl07kDJVFZcb9rsGwcfPY8ZCxcD0MtV/Q+yflCbaLL4RYcKXCBZXv0yOJEhxw=="

Validation
When encryption is performed, types and values in the card
and bank_account
objects are validated. This validation ensures that:
- Each field is of the correct type.
- Required fields are specified.
account_number
,routing_number
,card_number
, andcard_cvc_cvv
fields contain only numbers and are the correct length.- The card expiration date is valid.
- If either the first or last name card fields are specified, then the other field is as well.
- If the cardholder title field is specified, the first and last name card fields are as well.
- The DDS configuration is self-consistent. This means that:
- At least one destination is set.
- If
bank_account
is set, the validation ensures that either amount or percent allocation is set, orentire_allocation
istrue
. - If
entire_allocation
istrue
, the validation ensures that neither amount or percent allocation is set. - Amount and percent allocations are self-consistent:
value
,min_value
,max_value
are valid decimal numbers.0 ≤ min_value ≤ value ≤ max_value
for amount allocation.0 ≤ min_value ≤ value ≤ max_value ≤ 100
for percent allocation.
When a card_source
object is defined in your DDS configuration, the Argyle API validates it before encryption. This validation ensures that:
- If the
card_source
object is defined, thenbank_account
orcard
objects cannot be present in the DDS configuration. - The value of the
partner
attribute must beunit
. Accepted values can potentially change when more partners are integrated in the future.
Example DDS configuration for RAW_BODY:
{
"bank_account": {
"bank_name": "YellowHorizon",
"routing_number": "084101234",
"account_number": "9483746361234",
"account_type": "checking"
},
"amount_allocation": {
"value": "177",
"min_value": "177",
"max_value": "177"
}
}
