Flash call verification

[Pepe91]

In API flashCall verification is it possible to use a part of flashedCall number as an OTP code (e.g. last 4 numbers) instead of entering the whole number?

It doesn't have a good user experience to enter whole numbers in 30-40 seconds.

Hi,

Yes, by default the last six digits of your flashCall number is used - which is recommended to ensure sufficient security.

However, iIf you want to change this, contact Sinch Support who can help configure a different value. 

Thanks and kind regards,
