Text field numeric response only

Hi tshill4455,

You can add an additional field validator which limits the text field to only accept numeric input. However, I don't think it's editable from UI directly, and you'll have to make REST API calls to achieve this goal. If you are interested, I can share the detailed steps for you to follow.

Detailed steps would be great. I haven't explored the REST API calls yet but am willing to learn how to do that.  Thanks!

I'm back from the holiday break. It would be great if I could get the detailed steps you mentioned.

Hi tshill4455,

The approach I am suggestion leverages the Interactive API Reference to facilitate the process of invoking APIs:
Step1: At the interactive API reference page, click the "Authorize" button and set the API Key as "Basic your_api_key"

Step2: Assuming you have such a layout

At the interactive API reference page > find the "Layouts" section > "GET /api/layouts" API > set the layout name as the parameter "search" and hit "Try it Out":

The response should return "count" 1 with the layout JSON, copy it to any text editor

Step3: In the JSON payload, you need to locate the text field and find below data:

-layout/package ID

-document ID

-approval ID (approval means signature in OneSpan Sign)

-field ID

Copy the field JSON to any text editor and modify the "validation" > "pattern" as "^[-+]?[0-9]*\\.?[0-9]*$", this regex expression means numeric input only

Step4: At the interactive API reference page > find the "Approvals" section > PUT /api/packages/{packageId}/documents/{documentId}/approvals/{approvalId}/fields/{fieldId} 

Specify the four IDs as the parameter and the modified JSON as the request payload:
{
  "binding": null,
  "validation": {
    "group": "",
    "required": false,
    "maxLength": null,
    "disabled": false,
    "errorMessage": "Please insert a number!",
    "enum": null,
    "minLength": null,
    "minimumRequired": null,
    "errorCode": null,
    "pattern": "^[-+]?[0-9]*\\.?[0-9]*$"
  },
  "id": "AkZzA1tjf2QS",
  "page": 0,
  "data": null,
  "subtype": "TEXTFIELD",
  "width": 163.7999939918518,
  "height": 36.39999866485596,
  "fontSize": null,
  "extract": false,
  "formattedValue": "",
  "left": 506.99998140335083,
  "top": 447.19998359680176,
  "extractAnchor": null,
  "type": "INPUT",
  "value": "",
  "name": ""
}

And this will update the field to restrict the text field to allow numeric only.

Thanks for recomendation!
