A WooCommerce order with variable products, rebuilt line by line as a Xero quote

A WooCommerce event starts the scenario the moment a quote request is placed, and the next module fetches the full order, so every later step works from the complete record rather than from the event's summary.

The scenario searches Xero's contacts for the customer. A router then takes one of two routes: an existing contact goes straight on to the lines, and a new customer is created in Xero first, with an error handler on that step that skips the bundle rather than stopping the scenario.

One iterator walks the order's line items, a second walks each line's variation, and a third walks its metadata, which is where the customer's chosen options live. A text aggregator joins what the inner iterators find, so each quote line can carry the options that were chosen.

JSON modules create and parse each line in the structure Xero's quote expects, and an array aggregator collects the lines into one array, so the Create Quote module runs once per order with every line on it, not once per line. Both routes, new and existing contact, end in the same line-building chain and the same Create Quote step.

Beyond this audited scenario, the order flow we built for this business also carries Stripe payments, the customer's region, tax per line and line descriptions into Xero. That wider scope is our own account of the build; the audit covers only the quote scenario described above, so it is not set out module by module here.
