Change the Event Timings

You can change the default timings by supplying custom values for pin_expiry and/or next_event_wait in the initial request:

• pin_expiry:
  • The time after which the code expires
  • Must be an integer value between 60 and 3600 seconds
  • The default expiry differs between workflows but will be 300 seconds in most cases
• next_event_wait:
  • The time after which Nexmo triggers the next verification attempt
  • The default timing differs for each workflow

If you specify values for both pin_expiry and next_event_wait, the value of pin_expiry must be an exact multiple of next_event_wait.

Examples

The table below shows some example values and the effects when used with the default workflow (SMS -> TTS -> TTS):
