Show the instructions bank details to your customer. When the customer pays, reconcile deposits with /v1/deposits and match rows by funding_account_id:

curl --request GET \
  --url 'https://api.sandbox.daya.co/v1/deposits' \
  --header 'X-Api-Key: YOUR_SANDBOX_API_KEY'

Create an offramp

First resolve the destination bank account:

curl --request POST \
  --url https://api.sandbox.daya.co/v1/banks/resolve \
  --header 'X-Api-Key: YOUR_SANDBOX_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "account_number": "0690000031",
    "bank_code": "044"
  }'

Then create a temporary offramp to accept stablecoins and settle as an NGN payout.
