Hi,I am just started pay pal integration with paypal_lib library

Everything goes fine except the return url.

Please help me to set up auto return URL in pay pal.

Thanks

Well, I don't know how to do it with the paypal_lib, but with raw code I usually just pass a hidden field in the form:

<input type="hidden" id='url_return' name="return" value="{RETURN_URL}">
