# Product 360: Event Stream

## See Buy Box, suppression, stock and price events on your Amazon products within hours, get alerts in Slack or email, and fix problems the same day.

Event Stream tracks the problems that cost you sales on Amazon: a lost Buy Box, a suppressed ad or listing, a stockout, and price changes. You see them within a few hours instead of spotting the drop in next week's numbers, and you can have a summary sent to Slack or email.

### Before you start

Event Stream is part of Product 360. Turn on Product 360 for each account you want to track:

1. In the left navigation, go to **Intelligence › Product 360 › Getting Started**.
2. Pick the organization and account at the top of the page.
3. Turn on **Subscribe to Product 360**. Product 360 is free for the first 12 weeks and paid after that. Your Intentwise account team can give you pricing. To subscribe several accounts at once, use **Global Settings › Account Management**.
4. Make sure the account has SP-API access. See the setup guides for [Seller Central](https://help.intentwise.com/steps-to-provide-access-to-amazon-seller-central-accounts?hsLang=en) and [Vendor Central](https://help.intentwise.com/steps-to-provide-api-access-to-amazon-vendor-central?hsLang=en).

![Product 360 Getting Started page with the Subscribe to Product 360 toggle](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-01-getting-started.webp?width=670&name=event-stream-01-getting-started.webp)

Data can take up to 24 hours to load after you subscribe or connect SP-API. If you connected Seller Central before September 2026, re-authorize SP-API to give Event Stream the access it needs. The steps are in [How to reauthorize access](https://help.intentwise.com/steps-to-provide-access-to-amazon-seller-central-accounts?hsLang=en).

### Open Event Stream

Go to **Intelligence › Product 360 › Event Stream** and pick the organization and account at the top of the page. Event Stream shows one account at a time.

### Sellers and vendors

| Account type | How often events update | Tabs you see |
| --- | --- | --- |
| Seller | Every 1 or 3 hours (your choice) | Latest and Daily Digest |
| Vendor | Once a day | Daily Digest |

### Event types

| Event | What it means | Status |
| --- | --- | --- |
| Buy Box | You lost or won the Buy Box. The event names the seller who won it. | Unresolved while another seller has the Buy Box. Fixed once you win it back. |
| Suppression | Amazon suppressed the product's ads, its listing, or its appearance in search. | Unresolved until the suppression clears, then Fixed. |
| Stock | The product went out of stock or came back in stock. | Unresolved while the product is out of stock, then Fixed. |
| Price | The price went up or down. | None. Price changes are often on purpose, so Event Stream records them without marking them unresolved. |

### Latest tab (sellers)

The Latest tab covers the most recent refresh window. The tab label tells you which window you picked: **Latest (1H)** or **Latest (3H)**. **Last refreshed** shows when the events were last updated, in your account's time zone.

![Event Stream Latest tab showing recent product events](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-02-latest-tab.webp?width=670&name=event-stream-02-latest-tab.webp)

The four cards at the top are **Buy Box**, **Suppression**, **Stock Issues** and **Price Changes**. Each one shows how many events came in and how many products they touched, split into unresolved and fixed. Price Changes splits them into reduced and increased instead. Click a card to filter the grid to that event type.

Below the cards, each row is a product, with a column each for Buy Box, Suppression, Stock and Price. A cell shows the latest event, like "Back in Stock", with an Unresolved (!) or Fixed (✓) marker. Products on your watchlist have a filled bookmark icon next to the ASIN.

#### Event details

Click a cell and its details open under the row. You'll see the status as of the last refresh and a **What happened** timeline of each change, newest first. For Buy Box events, the details also list every seller you lost the Buy Box to and how many times.

![Expanded event showing Buy Box change details](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-03-event-details.webp?width=670&name=event-stream-03-event-details.webp)

### Daily Digest tab

The Daily Digest uses the same cards and grid, but for a full day. Pick a day from **Viewing**, or use the arrows to move back and forward. It goes back 14 days.

When a product had more than one kind of suppression that day, the cell says so, for example "Ad, Listing +1 more". Open it to see each suppression and when it cleared. Price cells show the latest price along with the day's low and high.

![Event Stream Daily Digest tab](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-04-daily-digest.webp?width=670&name=event-stream-04-daily-digest.webp)

### Filter events

Use **Filter** to narrow the grid by product, event type or status. To find a specific product, filter by it. Clicking a summary card also filters to that event type.

### Use the watchlist

If there are a few products you watch closely, like new launches or your best sellers, put them on the watchlist. You can then view them on their own and limit alerts to them.

1. Select the checkboxes next to the products.
2. Choose **Add to watchlist**. To take products off, select them and choose **Remove from watchlist**.
3. Switch from **All products** to **Watchlist** to see just those products.

![Event Stream Watchlist tab](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-05-watchlist.webp?width=670&name=event-stream-05-watchlist.webp)

Both tabs use the same watchlist. You can only add products that already appear in Event Stream, so a product with no events yet won't be in the list.

### Change the refresh window (sellers)

1. Choose **Settings**, or click **change in settings** next to the refresh time on the Latest tab.
2. Under **Event settings › Refresh Window**, choose **Every Hour** or **Every 3 Hours**.
3. Choose **Save settings**.

![Event Stream refresh window and last refreshed time](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-06-refresh-window.webp?width=670&name=event-stream-06-refresh-window.webp)

This setting applies to everyone who uses this account.

### Get alerts in Slack or email

Alerts send a summary of new events to Slack, email or both, so your team hears about a lost Buy Box or a suppressed listing without logging in to check.

#### What's in an alert

Each alert names the organization and account, says whether it covers all products or only your watchlist, and gives the time window. It then counts events by type: Buy Box lost and won back, suppressions and clears, out of stock and restocked, and price reductions and increases. **View in Intentwise** opens Event Stream, and **Notification settings** takes you to these settings.

![Preview of an Event Stream alert](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-09-alert-preview.webp?width=670&name=event-stream-09-alert-preview.webp)

#### Set up alerts

1. Open Event Stream, select the account you want alerts for, and choose **Settings**. Slack won't connect while All Accounts is selected.
2. Under **Event Thresholds**, set the **Price change threshold**. You'll only get a price alert when a price moves by at least this percentage. Buy Box, suppression and stock events always alert.
3. Under **Notify me about**, choose **All products** or **Watchlist only**.

![Event Stream alert settings](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-07-alert-settings.webp?width=670&name=event-stream-07-alert-settings.webp)

1. Under **Notification Channels**, set up Slack, email or both: 
     - Slack: connect your workspace and pick a channel, then turn on the Slack toggle. Use **Change channel** to post somewhere else.
     - Email: turn on the Email toggle, then search for people by name or email and add them. Only users on your Intentwise account can receive alerts. Add new users in **Global Settings › Account Management**.
2. Open **Preview** to see what your team will get.
3. Choose **Save settings**.

![Alert channel settings for email and Slack](https://help.intentwise.com/hs-fs/hubfs/help-center/product-360-event-stream/event-stream-08-channels.webp?width=670&name=event-stream-08-channels.webp)

#### How often alerts arrive

Seller accounts get an alert after each refresh, every 1 or 3 hours depending on your refresh window. Vendor accounts get one a day. Event Stream also sends a Daily Digest summary by default, on top of the regular alerts.

A few tips: start with Watchlist only and a short list of products your team acts on, and widen it later. If price alerts get noisy, raise the threshold. Send alerts to a channel the people who fix listings and inventory already read.

### Reading Buy Box events

When an event says you lost the Buy Box to "Competitor", Amazon didn't share the seller's name. Otherwise the event shows who won it.

You might also see Buy Box losses to two or more sellers at the same minute. That happens when sellers run separate offers on the same product, for example FBA and FBM, or Prime and non-Prime.

If you sell through both Vendor Central and Seller Central, Amazon treats those two offers as different sellers, so a Buy Box event can show your own seller account as the winner. If that's throwing off your reporting, talk to your Intentwise account team.

### Common questions

#### How is losing the Buy Box different from a suppression?

Losing the Buy Box means another seller's offer is now the featured one. A suppression means Amazon took something down: the product's ads, its listing, or its place in search results.

#### How far back can I see events?

The Daily Digest covers the last 14 days. Events can't be exported.

### Troubleshooting

| Problem | What to check |
| --- | --- |
| Event Stream is empty | Smaller catalogs can go a while without an event. Otherwise, check that Product 360 is turned on in Getting Started, that SP-API is connected, and that 24 hours have passed. Seller accounts connected before September 2026 need to [re-authorize](https://help.intentwise.com/steps-to-provide-access-to-amazon-seller-central-accounts?hsLang=en). |
| No alerts arrive | Make sure the account has events and the Slack or Email toggle is on. If you picked Watchlist only, make sure there are products on the watchlist. |
| Can't add an email recipient | The person has to be a user on your Intentwise account. Add them in **Global Settings › Account Management** and try again. |
| Can't connect Slack | Pick a single account at the top of the page instead of All Accounts, then open Settings again. |
| Too many price alerts | Raise the price change threshold, or switch to Watchlist only. |
