+We have a templatetag to generate a payment button that is quick and easy to

+
+<div class="my-button">
+{% render_checkout amount=9999 name="Test payment" currency="COP" extra1=request.user.id extra2="membership-3" request=request %}
+</div>

+[here](https://github.com/gustav0/epayco_django/blob/master/epayco_django/templatetags/epayco_checkout.py).
