How to Add Validation to Textbox Field

When using the textbox form field, you have the option to include validation based on your needs, which will specify the type of text that signers can enter in the field. The available options are only numbers, regex, currency, email, and none.

• Only Numbers: Signers can only enter numeric numbers in the textbox area.

• Regex: Customize the validation by selecting the regex option, entering the desired regex value, and adding a description to inform signers of the needed format.

• Email: Restrict email input to the textbox area.

• Currency: The signer can only input currency values in the textbox area.

Adding Only Numbers Validation using API

The following sample code snippet demonstrates how to add only number validation to a textbox field:
