}

2. Initialize Bank Transfer

Initialize a bank transfer transaction:

curl --location '{{baseurl}}/banktransfer/initialize' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer YOUR_SECRET_KEY' \
--data-raw '{
    "email": "test@email.com",
    "amount": "100",
    "currency": "NGN",
