HigherStack Answer piping
Insert what someone typed earlier into later text — labels, messages, emails and redirect URLs.
Piping personalizes a form by dropping a previous answer into later text. Wrap a field’s name in double curly braces and it’s replaced with that answer.
Syntax
Thanks, {{first_name}}! We'll email your quote to {{email}}.Where you can pipe
- Completion screen heading and message (see Completion screens).
- Confirmation emails to the respondent, and notification emails to you (see Notification & confirmation emails).
- Redirect URLs — append answers as query parameters, e.g.
https://example.com/thanks?email={{email}}. - Field labels and placeholders — reference an earlier answer in a later question, updating live as they type.
Note
If a referenced field has no answer yet, the placeholder simply resolves to nothing — so piped text never shows raw {{…}} braces to the respondent.
