Automating Facebook Marketplace Listings from CarGurus

[Haron]

Hi everyone,

I’ve been working on a small tool to help automate posting vehicles to Facebook Marketplace, and I wanted to share it here to see if it might be useful for anyone managing inventory online.

One thing I noticed is that a lot of dealerships still manually copy vehicle listings from sites like CarGurus when posting to Facebook Marketplace. That usually means copying:

• Title
• Description
• Mileage
• Price
• Downloading and uploading photos

If you're posting multiple vehicles, it becomes pretty repetitive.

So I built a Chrome extension that extracts the listing details from CarGurus and prepares the Facebook Marketplace listing automatically.

The goal is simply to remove the copy/paste workflow and speed up the listing process.

Current capabilities:

• Extracts vehicle details from CarGurus listings
• Pulls vehicle images automatically
• Prepares the Facebook Marketplace listing form

Right now it supports CarGurus, and I'm planning to add support for other sites depending on demand.

The extension is free to use, and I’d really appreciate feedback from anyone who lists inventory on Facebook Marketplace regularly.

Chrome Web Store:
Facebook Marketplace Auto Poster - Chrome Web Store

If anyone has suggestions or other inventory sites they'd like supported, I'd love to hear them.

Hi Haron,

It looks amazing tool, I liked that.

I noticed that mileage is always entering 300. Other than that looks solid.

Careful with this. Using unauthorized extensions to scrape Marketplace can get your account flagged or banned pretty fast.

Great to hear that you like it!

Thanks for pointing that out — I actually just noticed there’s a bug affecting the mileage field, so I’ll get that fixed in the next update.

I’m also planning to add AI-powered description paraphrasing, so dealers can quickly generate a slightly different version of the vehicle description when posting to Facebook Marketplace.

Also, I’m planning to add support for more sites soon — which sites would you find most useful next?

And if you find the extension helpful, a review on the Chrome Web Store would really help.

That’s a fair concern. The extension doesn’t scrape Facebook Marketplace or run listings in the background. It simply pulls the vehicle information from the source listing (like CarGurus) and helps populate the Marketplace form to reduce manual copy/paste.

The listing process still happens directly in the user’s browser session just like a normal listing workflow.
