GPT Merchant

Hello,

We use Joomla + HikaShop and already rely on the HikaShop Google Products / Merchant feed plugin.

OpenAI is onboarding merchants for ChatGPT product feeds and Instant Checkout through its Agentic Commerce documentation. At this stage, our priority is the product feed, not checkout.

We would like to know:

1. Do you have any plans to support an OpenAI / ChatGPT merchant product feed natively?
2. If not, what would be the cleanest way to generate a second feed from HikaShop based on the existing Google Products plugin?
3. Can the current plugin output be customized or extended easily to map additional fields required by another merchant feed specification?
4. For stores with variants, multipacks, custom product fields, brand, GTIN/MPN and stock, what export approach would you recommend to avoid modifying core files?

Our store has around 1,600–2,000 unique SKUs.

Thank you.
