Is this compatible with WP 3.9 WooCommerce 2.1/2.2 ?

Hi Marcelo, lood this is my demo site running the latest woocommerce and the latest Payu Latam Gateway
https://demo.thecodeisintheair.com/woocommerce/
Hope it helps

ok, I’ll check it out then.

Then, this will be the official plugin for Dineromail by Payu Latam?

No, i’m a freelance developer but even though i’m a partner with PayU Latam the plugin is not official.

also im not sure if DineroMail uses the same APIs I use for PayU Latam integration, i haven’t check that yet.

All right.

Have you tested it or know if it will work with Dineromail accounts based in Argentina? Should it theoretically work with every Latam based Dineromail account?

I would have to check to documentation for dineromail to give you a final on that.

ok, please, it will be good to know.
Dineromail is the second MUST HAVE after Mercadopago here in the spanish talking countries of Latam.

well they seem completely different,
although the rates from dineromail seems to be the same from payulatam.com, and the service is the same.

you should check the main platform which this plugin is made for.
