Checkout Plus: Custom Input Character Minimum and Range

Custom Input validation now supports a character minimum or a min and max range, so you get more detailed answers at Shopify Checkout.

Improved

Checkout Plus Custom Input settings with Input Validation set to Text Field - Character Minimum and Minimum characters set to 200
Character minimum in Custom Input validation

Custom Input in Checkout Plus can now require a character minimum, or keep answers within a min and max range. Before, you could only set a maximum.

That means more useful answers, like detailed gift messages, delivery notes, or survey responses. For example, set Minimum characters to 200 so buyers must enter at least 200 characters.

Find it in your Custom Input settings under Input Validation. Choose Text Field - Character Minimum and set Minimum characters, or pick the range option to set both a min and a max.

Why it helps
  • Get answers with enough detail to act on
  • Fewer one-word replies in gift messages, notes, and surveys
  • Keep answers within a length that fits your needs

This update is available now in Checkout Plus. Open your Custom Input settings, pick an option under Input Validation, and get the detail you need.
