# How to Fix "Item ID Mismatch" in Google Ads or Merchant Center?

| This guide explains how to fix the "Item ID Mismatch" error in Google Ads or Google Merchant Center.
---

## 1. Understand the Issue

The error means Google cannot link your conversions to the correct products.
This happens when the **Item IDs** sent from **wetracked.io** don’t match the **Item IDs** in your **Google Merchant Center** feed.

To fix it, you need to:

1. Find out which Item ID your Merchant Center uses.
2. Update the **Item ID Template** inside your wetracked.io dashboard to match that format.

---

## 2. Find the Correct Item ID

### Option A: Using Google Merchant Center

1. Log in to **Google Merchant Center**.
2. Go to **Products → All Products**.
3. Click on any active product.
4. Look for the **Item ID** field. This is the exact value Google expects.

### Option B: Using Google Ads (If You Don’t Have Merchant Center Access)

1. Open **Google Ads**.
2. Go to **Campaigns → Products**.
3. Click on a product to view its details.
4. Take note of the **Item ID** value shown.

## 3. Update the Item ID Template in wetracked.io

1. Log in to [wetracked.io](https://app.wetracked.io).
2. Open your **Store**.
3. Scroll down to **Google Ads**.
4. Click the **edit** (pencil) icon.

In the **Item ID Template** section, set the format to match the Item ID format in your Google Merchant Center.

* By default, wetracked.io uses **Variant ID**.
* If your Merchant Center uses Variant IDs, no changes are needed.
* If it uses a different format (e.g., Product ID), update the template accordingly.

### Example only: If you are using Product ID

If your Merchant Center uses **Product ID**, configure the Item ID Template to use Product ID as shown below.

* The change takes effect immediately.
