different email templates for same status

This is not working as I would expect:

email template

<perch:if id="sku" match="eq" value="SDC_001">
                    <perch:shop id="intro_1" type="textarea" label="Introduction Basic" markdown="true" editor="markitup" size="m" />
                </perch:if>
                <perch:else />
                    <perch:shop id="intro_2" type="textarea" label="Introduction Feng Shui" markdown="true" editor="markitup" size="m" />
                </perch:if>

I tested with different SKUs and always receive the intro_1. Is it just id="sku" I should test against?

The rest is pretty much the default order_paid.html.

So later in the template the order item's info are being accessed with perch:orderitem.

I understand that the ordered item's SKU is not an exception and should also be accessed with <perch:orderitem id="sku" /> . But then I suppose I can't put this into a perch:if right?

Yeah and it's not scalable anyway. So I'm investigating a different approach. I want to send a POST request to a Zapier endpoint with a payload of a json object holding the order information. This will then call the Sparkpost API and send the email using a template which can include logic.

An example request

curl -v -H "Accept: application/json" \
        -H "Content-Type: application/json" \
        -X POST \
        -d '{"first_name":"Bryan","last_name":"Helmig","email":"client@test.com", "product":"T-shirt"}' \
        https://zapier.com/hooks/catch/blablah/

What is not clear to me is when exactly I'll have to make the request.

Currently I have a checkout.php page where I call the perch_shop_payment_form() and the success.php where there is only some text for now. Do I have the order information available in php in any of these steps/pages?

I hope the question makes some sense :)

I think I found it. I will try to do it in the success page with perch_shop_order for the order info and some members function for the member's info. All good for now, thanks!
