Seismic Card Issuance API

Programs

A program is a card product definition. It sets the product type and currency for the cards issued under it.

Field	Values
`productType`	`DEBIT`, `PREPAID`, `CREDIT`
`currency`	ISO currency code, e.g. `USD`
`status`	`ACTIVE`, `PAUSED`, `CLOSED`

cURL

curl -s -X POST 'https://api.seismic-cards.systems/v1/programs' \
  -H 'Authorization: Bearer YOUR_TOKEN' -H 'Content-Type: application/json' \
  -d '{ "name": "USD Virtual Debit", "product_type": "DEBIT", "currency": "USD" }'

The underlying issuing rail is chosen and managed by Seismic. It is an implementation detail and never appears in your API responses.

Each program can use wallet service (Seismic deposit address) or bring-your-own wallet (byo_wallet). Configure with PUT /v1/programs/{id}/funding-config. Full walkthrough: Card funding (wallet & BYO).

Accounts

An account holds funds and backs the cards issued under a program. Create an account before issuing cards — card issuance references account_id and provisions issuer-side funding on first use.

Balances are reported in minor units (cents). available is what’s spendable after holds.
