Customization Updates for Checkboxes and Text Inputs

SignatureAPI has shipped new customization options for checkbox and text input places, making it easier to line fields up with existing document layouts and match the visual style of the underlying PDF. These options apply during the signing ceremony and give developers more precise control over how recipient fields render.

What’s New

• Checkbox height: A new height parameter on checkbox places lets you adjust the visual size of a checkbox so it aligns with existing form boxes in your documents.
• Text input font size: The new font_size parameter controls the size of text a recipient enters, so input matches the surrounding document typography.
• Text input width: A new width parameter defines how wide the input field renders during the ceremony, which is useful for longer entries like full names and addresses or for tight, constrained fields.

Backwards Compatible

These additions are purely additive. Existing templates and envelopes continue to behave exactly as before, and the new parameters are optional. If you’re happy with the current defaults, no action is required.

These updates were built in response to customer feedback from teams working with dense or highly styled forms where default sizing didn’t always match the source document.
