For security reasons, form links expire after a set period of time. The expiration window depends on how the link is generated or delivered.
When sending links by email:
Standard form links expire 60 days after they are created.
When sending links by SMS:
When a form link is sent via SMS, a shortened link is used to save characters. These SMS short links expire after 14 days.
When manually entering a code, or scanning a QR code:
Forms accessed manually expire after 1 hour.
Note: If the same form is sent to the patient again, the expiration timer resets.
