Template Variables

Content coming soon

Full documentation for template variables and dynamic field substitution is coming soon. Check the changelog for updates.

Template variables let you inject dynamic values into envelope fields at send time — names, dates, reference numbers, and any other text that changes per recipient. This page will cover:

  • How to declare variables in a template
  • Passing variable values when creating an envelope from a template (POST /v1/envelopes)
  • Required vs optional variables and default values
  • Validation errors when required variables are missing
