From inventory page to live listing — step by step.
Once you're set up, this is the workflow you'll repeat every time you post. It takes under 15 minutes for a batch of 5 vehicles.
In Chrome, go to your dealer's inventory URL — the same page you saved in Settings when you first set up the extension.
This is usually your DMS or dealer website's "Inventory" or "Cars for Sale" page. Make sure you're logged into your DMS if the inventory page requires authentication.
Click the PostMyDeal.ai icon in the top-right of your Chrome browser. The extension popup opens and immediately begins scanning the page.
You'll see a loading indicator while the extension reads the inventory. This usually takes 5–15 seconds depending on how many vehicles are on the page.
The first time you open the extension, you'll be asked to sign in with your PostMyDeal.ai email and password. After that, your session is saved and you won't need to log in again unless you sign out manually.
- Enter the email and password you used when creating your account at postmydeal.ai.
- Click Sign In. The extension validates your subscription and loads the vehicle results.
After scanning, the popup shows a list of all vehicles found on the page with their photo, title, price, and mileage. Two scraping modes are available depending on your DMS:
- Use the checkboxes on each vehicle card to select the ones you want to post.
- Or click "Select All" to check everything on the page at once.
- The post bar at the bottom shows your selection count: "POST 3 SELECTED TO MARKETPLACE".
When you click POST, the extension sends each vehicle's photos to Google Gemini Vision AI, which reads the images and extracts: year, make, model, trim, price, mileage, color, transmission, condition, and VIN.
You'll see a progress screen in the popup showing which vehicle is being analyzed: "Analyzing 2 / 5 vehicles…". The background service worker handles this even if you close the popup — you don't need to keep it open.
After AI Vision finishes, the extension opens Facebook Marketplace → Create new listing → Vehicle for sale in a new tab and starts filling in all fields automatically:
- Title — Year Make Model Trim (e.g. "2021 Toyota Camry SE")
- Price — Pulled directly from your DMS listing
- Mileage — Formatted correctly for Facebook's input field
- Color, Transmission, Condition — Selected from the dropdown menus
- Description — AI-generated from the vehicle details
- Photos — Up to 25 images uploaded from your DMS listing automatically
After the first vehicle is queued and Facebook opens, the extension waits 45 seconds before processing the next one. This anti-detection cooldown mimics natural human behavior and protects your Facebook account.
When the extension finishes filling in the listing, you review it and hit Publish. We recommend a quick 10-second scan:
- Confirm the price is correct — make sure it matches what you intended to list.
- Glance at the photos — make sure the right vehicle's photos loaded and the cover photo looks good.
- Check the description — add any personal notes if you want (optional but increases inquiries).
- Click Publish on Facebook. The listing goes live immediately.
- The extension automatically moves to the next vehicle in your queue after the 45-second cooldown.
