COD form orders never pass through Shopify checkout, so your usual checkout tracking does not see them. The Ad tracking tab on the COD Form page sends the purchase event itself. The first card is Meta Ads, "Track COD form orders with Meta Pixel and Conversion API." Note what is sent: a purchase event, after a successful order, and nothing else. There is no product view or add to cart event from the form.
There is no Facebook login and no pixel picker. You type the pixel in yourself. On a new install the card reads No active tracking, "Meta tracking is not configured yet.", with an Add tracking button that opens a window. Fill in Pixel ID, digits only, described as "Used to select the Meta account that will receive purchase events." A How to get your Pixel ID link opens instructions. Label (optional) is visible only in the app and helps when you run several accounts.
In the same window, Conversion API access token takes a token you generate in Events Manager, under your pixel's Conversions API settings. The help text is "Improves tracking accuracy by sending events directly from the server." Press Save. The token is stored encrypted and the field then reads Token encrypted and saved, with Edit token to replace it.
The card now reads Meta tracking is active and, underneath, Last event detected with a time, or No events detected yet. There is no test event button in the app, so place one real test order on your storefront, then open Events Manager and confirm the value and the currency against the order in Shopify admin.
Each saved pixel gets its own row, headed Pixel ID and the number. The toggle on the row stops it sending without losing the settings, and the card heading changes to Meta tracking is paused. The remove button asks first, warning that this stops events and that you can add the pixel again at any time.
Add the Conversion API token even if the pixel works: it is the part ad blockers cannot stop.
Check the order value in Events Manager against the order in Shopify admin on your first test.
The other nine ad platforms are set up on the same tab, each with its own card.
