To get a template onto your storefront you exported a .mex file from Invent, signed in to the admin area, opened the MegaEdit product (or created one), and uploaded the file on its Import page. Then you opened the product in the editor to test it. Every change meant doing it all again.

In the Invent panel, Preview and Publish send the template to your storefront for you. Preview opens it in the editor. Publish creates a new product from it, or replaces the template of a product you already have.

Sign in to your storefront's admin area as an administrator. In the admin menu, click Configuration (scroll down the menu if you do not see Integrations / API), then Integrations / API, then Connected Apps.

On the InDesign card, click Copy to copy the API key. Do not click Rotate token: it creates a new key, and the old one stops working straight away for everyone who uses Invent with this storefront.

In InDesign, open the Infigo Invent panel. Click the small menu icon at the top right of the panel.

In the menu, click Settings.

In Infigo Platform URL, enter the web address of your storefront, the same address you use to open it in a browser, for example https://yourstore.infigo.net. If your storefront's address has a path after the domain name, include it, but leave off any page name. Although the label says platform, use your storefront's address. In Infigo API Token, paste the key you copied: the API key on the Connected Apps card and the API token are the same thing. The hint text under the fields mentions the platform and Configuration > API Tokens. Ignore it and use the Connected Apps key. Leave Infigo Customer ID empty: it fills itself in the first time you preview.

Click Save.

Open the Export tab and click Start Validations. When they pass, the Preview and Publish buttons appear (see Part 2). To check the connection, run a preview.

Open your template in InDesign. In the Invent panel, click the Export tab, then click Start Validations. Fix anything it reports.

When the validations pass, the Preview, Publish and Export buttons appear. Click Preview. Invent saves the document, sends the template to your storefront and shows its progress in the panel. The Export File box can stay empty: only Export needs it.

The template opens in the editor in a separate window on top of InDesign. This can take a minute. Try the fields the way a customer would: check that each field changes the design, and that fonts, colours, dropdowns and dates behave as you expect. You do not need to click the editor's own Preview button. Close the window when you have finished.

In the admin area, open Catalogue, then Products, then Product Management. In the Product Name or SKU box, search for Invent Preview: the products appear there as unpublished MegaEdit products, and you can delete the ones you no longer need.

In the Export tab, run Start Validations, then click Publish.

If Product ID shows a number, delete it so the box is empty: the dialog remembers the last ID you used, and a number there replaces that product's template instead of creating a new product. Enter a Product Name and leave Published unticked. Click Publish.

Invent saves the document, sends the template to your storefront and imports it. A message tells you the product has been published, and the editor opens on it. Close the editor window.

Open Catalogue, then Products, then Product Management. In the Product Name or SKU box, type the product's name and click Search, then pick the row whose name matches exactly. It is a MegaEdit product with a price of 0, and its Published column shows a red cross: customers cannot see it yet.

Click Edit. Set its price, category and other details as you would for any product, then tick Published and click Save when it is ready.

In the admin area, open the Catalogue menu, then Products, then Product Management, find your product and click Edit. The page address ends with /Product/Edit/ followed by the product's ID, for example /Product/Edit/1234. Use this number, not the number shown on the MegaEdit Products list: they are different. The product must be a MegaEdit product on the same storefront as the key and address in your Settings.

In InDesign, open the Export tab, run Start Validations, then click Publish.

Type the Product ID. The dialog remembers the last ID you used, so check the number before you continue. When an ID is entered, the name and published options are not shown. Click Publish.

The product keeps its name, price, SKU, categories and published setting. Its template is replaced. If you renamed or removed fields, open the product in the editor to check the template works as you expect.

In the admin area, open the product and click MegaEdit config, then Mex Import. You do not need to upload anything here: just read Mex File Details below the upload box. It shows the file Invent uploaded and the date and time it was updated.
