# Inspect Callouts to Zuora

Limio allows you to inspect the callouts to Zuora generated when order is processed. This allows you to debug interactions and understand the flow of data between Limio and Zuora.

## Where can I view callouts?

1\. When looking at an event, click on the process\_event object in the first table.

2\. When looking at a process\_event look in the Callout table to find the callout you want to view and click on Details.

3\. You're presented with a JSON view of the callout including details like errors, request timings and order details

Callouts will vary depending on the original event. Generally, the most important callout will be the POST callout to <https://rest.apisandbox.zuora.com/v1/orders>. By inspecting this callout, you will be able to send the payload provided to Zuora Orders, for example for a New Order, a Cancellation, an Add/Remove Product, an Update product etc...

## Understanding Zuora Errors

When there is an error in the order process, the callouts can provide some extra details about the reasoning for the error.
