Variables - HireData Docs

With variables you can drop live data, like a candidate’s name, a job title, or a salary, straight into your emails, WhatsApp messages, forms, and automations.

What a variable looks like

A variable is a field key wrapped in double curly braces:

Hi {{ candidate.first_name }}, thanks for applying to {{ job.title }}!

When this is sent to a candidate named Sofia applying for a Backend Engineer role, it becomes:

Hi Sofia, thanks for applying to Backend Engineer!

The spaces inside the braces are optional:

{{candidate.first_name}} and {{ candidate.first_name }} behave the same.

Where you can use variables

You can use variables anywhere you write content that gets sent or stored:

Email — subjects and bodies
WhatsApp — messages and templates
Forms — questions and follow-up logic
Automations — field mappings and scheduled tasks

Providing a fallback

If a field is empty for a particular record, the variable is replaced with nothing. To show a default instead, use the default modifier:

Hi {{ candidate.first_name | default: "there" }}!

If the candidate has no first name, this sends “Hi there!”.

Transforming values with modifiers

Variables can do more than insert raw data. A modifier changes how the value appears. It can uppercase text, format a date, round a number, and much more. You add a modifier with a pipe (|):

{{ candidate.first_name | uppercase }}        → SOFIA
{{ job.salary | format_currency: "EUR" }}      → €65,000.00
{{ application.created_at | format_date: "d M Y" }}  → 14 Mar 2026

You can chain several modifiers, and each one acts on the result of the previous:

{{ candidate.last_name | lowercase | capitalise }}

See the full list on the Modifiers page.
