Add Complex Text Tags to a document

Text tags - specific combinations of symbols and letters that represent fillable fields.

Complex Text Tags can be added to a document in any text editor. They convert to fillable fields when users upload a document to SignNow.

To add a Complext Text Tag to a document, just type the tag name in double curly braces where you’d like to put a fillable field, like so: {{tag_name}}. Then, make a request to POST /document/fieldextract. In your request body, specify parameters of the field you saved place for with your {{tag_name}}.

Required parameters for a Complex Text Tag:

“tag_name” - duplicates the name without curly braces, e.g. tag_name

“role” - which role the field is assigned to, e.g. Signer_1

“label” - hint for the signer inside a fillable field about the field type, e.g. first_name or text_1; once the field is filled in, the value automatically appears in all the fields with the same label

“required” - whether the field is mandatory to fill in, e.g. true/false

“type” - could be “text”, “signature”, “initials”, “checkbox”, “radiobutton”, or “enumeration” (stands for a dropdown menu)

“prefilled_text” - editable text that appears in the field when the signer opens the document, e.g. Lucy

“validator_id” - data validation format for a field.

Check for available formats in Data Validators.

“width” - how many pixels wide the field is

“height” - how many pixels high the field is
