UNSUPPORTED_API_VERSION error code using square web api with android

Question

Starting a transaction using Square web api(Android) returns on given WEB_CALLBACK_URI with error_code as UNSUPPORTED_API_VERSION and error_description as "The installed version of square point of sales is too old. It doesn't support this version of the point of sale SDK"

I installed the latest Square app Version=4.57

I used the following code on my html page

<a  href="intent:#Intent;
action=com.squareup.register.action.CHARGE;package=com.squareup;
S.browser_fallback_url=http://08e71683.ngrok.io;
S.com.squareup.register.WEB_CALLBACK_URI=http://08e71683.ngrok.io/abc;
S.com.squareup.register.CLIENT_ID=sandbox-sq0idp-6Lo2W9zX8K9b08zKxmfUtw;
S.com.squareup.register.API_VERSION=v2;
i.com.squareup.register.TOTAL_AMOUNT=100;
S.com.squareup.register.CURRENCY_CODE=USD;
S.com.squareup.register.TENDER_TYPES=com.squareup.register.TENDER_CARD,com.squareup.register.TENDER_CARD_ON_FILE,com.squareup.register.TENDER_CASH,com.squareup.register.TENDER_OTHER;
end">
 Send me $
</a>

I tried a lot in finding solution on google but couldn't find it. I hope there would be someone for help.

I think your issue is that you are trying to use a nonexistent version of of the Point of Sale API. Chagne S.com.squareup.register.API_VERSION=v2; to S.com.squareup.register.API_VERSION=v1.3;and see if you have success.
