How long is a URL-link using a checksum token from CiviCRM valid?

And can you send multiple emails using same token?

When does the expiration clock start ticking?

1 Answer 1


I found it myself:


Default setting is 7 days.

  • To answer your follow-up - yes, you can send multiple emails with the same checksum, but the clock starts ticking when the checksum is first generated. Dec 18, 2020 at 17:03
  • so in that sense it isn't the 'same' checksum, it is just 'a' checksum token.
