Creating an authorization without capture

This payment mode allows to verify that the buyer's card data is correct without debiting it.

If needed, the merchant will be able to debit the card with the desired amount by using the Duplicate function of the Back Office. To do so:

  • the manual validation mode must be used,
  • the merchant must not validate transactions manually.
  1. Use all the fields of the table below to create your payment form.
    Table 1. Field list - Authorization without a capture
    Field name Description Value
    vads_site_id Shop ID E.g.: 12345678
    vads_ctx_mode Operating mode TEST or PRODUCTION
    vads_trans_id Transaction number Eg.: 123456
    vads_trans_date Date and time of the payment form in UTC format E.g.: 20140129130025
    vads_amount Payment amount (in the smallest currency unit) 100 (for 1 euro)
    vads_currency Code of the payment currency Eg.: 978 for euro
    vads_action_mode Acquisition mode for credit card data INTERACTIVE
    vads_page_action Action to perform PAYMENT
    vads_version Version of the exchange protocol V2
    vads_payment_config Payment type SINGLE
    vads_capture_delay Delay before capture by the bank 0
    vads_validation_mode Payment validation mode 1
  2. Set the value of the vads_amount field to a small amount. It will not affect the authorization limit of the card.
  3. Set vads_validation_mode to 1.
  4. Fill in the vads_currency field with the code of the desired currency using the currency table (example: 978 for Euro; 840 for US dollar).
  5. Add optional fields according to your requirements (see chapter Using additional functions).
  6. Compute the value of the signature field using all the fields of your form starting with vads_ (see chapter Computing the signature).
