Additional Functions

The MWPayframe and tdsCheck object also have some additional functions that can assist with your implementation.

Function	Description
mwCardTypeUpdated	This is a callback function that is called whenever the card number field is updated. It returns the cardType, cardBin, and whether the card is valid (in that order) as parameters of the function.
reset	This function is used to reset the payframe in order to process a second transaction. After processing your first transaction, you won't be able to submit the payframe again unless it is reset.
refresh	This function is used to refresh the styling of the payframe. If the payframe loads incorrectly or incompletely, you can use this function to reapply the styling.
loading	This is a callback function that is called when the payframe begins loading, after being deployed. You can use this to trigger a loading animation or effect if you wish.
loaded	This is a callback function that is called when the payframe has finished loading. You can use this to disable any loading animations you may have started.
disable	This function is used to disable the payframe object to stop it listening to messages from the payframe iframe. Use this function before instantiating a new payframe, so that messages will be sent to the new payframe instead of the old payframe.

Function	Description
destroy	This function is used to close the 3DS verification window after verification has completed
loading	This is a callback function that is called when the 3DS verification window begins loading. You can use this to trigger a loading animation or effect if you wish.
loaded	This is a callback function that is called when the 3DS verification window has finished loading. You can use this to disable any loading animations you may have started.
link	This function is used to link the tdsCheck to an already-created mwPayframe. If you have written loading and loaded functions for the mwPayframe, this function will make the tdsCheck use the same functions, so you don't have to write them again.
