Callbacks are optional or mandatory? about spid-tech-docs HOT 7 CLOSED

Also add an important alert thingy with this:

It is of uppermost importance that you handle these callbacks and retrieve the correct order status so your systems are in sync with SPiD!

We expect that you implement some sort of monitoring of this integration with SPiD, since it directly affects your order-management systems and in the end your users/customers.

Please ensure that your callback endpoints are accessible by SPiD through your firewalls and that errors generated by the your callback endpoint are monitored and handled.

Thanks for the issue, I'll fix these first thing in the morning!

We added the last point to the /callbacks page. The first point will be added to the payment guide (and possibly other places, like payment endpoints).

According to @claesb, the callbacks are optional. How does that mesh with this message?

They were optional (as they were for Payex as well when we first integrated SPiD with Payex). This is now a requirement, for obvious reasons on Payex (sync problems on order status).

As we will be de defacto system for payments for our clients, we've decided to make the callback handling a requirement because our client's too need to have their systems in sync. Although this can be optional for some projects it should be decided and understood by all stakeholders on our project by project base. We must still communicate it as a requirement, specially for media companies, that today doesn't have real experience selling digital products.

That is really not true.

If you are NOT using our subscription/product/access logic, and you actually have a need to know order information, then this is a 'requirement'.

If you are using our subscription/products/access logic, there is no need for it at all.
But if you still wish to have order information, we provide it through the API and an ESB integration.

Meaning, you might aswell retrieve order information, or any other information through API polling instead of a callback functionality running every 5 minutes.

Suggestion: Figure whether callbacks are required or not, open new issues with concrete tasks.
