Notify Me sign-ups are stored in Klaviyo, not in Bloom. Connect your account once and pick the list sign-ups land in.

​
Steps

  1. In Shopify admin, open Apps → Bloom.
  2. Go to Notify me → Settings, then Integrations → Klaviyo integration.
  3. Click Connect Klaviyo.
  4. Authorise Bloom in the Klaviyo window that opens.
  5. Pick your Back-in-stock list. Most stores use a dedicated list like Back in stock. Create a list makes one without leaving Bloom, and leaving it on Klaviyo account default subscribes shoppers without adding them to a list.
  6. Click Save.
Once connected the panel shows Connected with Granted scopes, and a Disconnect button. If disconnecting fails, Bloom keeps the connection and shows an error - try again. Bloom asks for access to your lists, profiles, events, flows, metrics and segments. It uses flows, metrics and segments for back-in-stock results and to add UTM tracking to your back-in-stock flow emails.

Connections made before this access was added keep working, but show Reconnect Klaviyo on Home, in Notify me → Settings and on Notify me → Overview until you reconnect and approve it.
If you remove Bloom inside Klaviyo, Bloom shows Klaviyo is disconnected next time you open the Klaviyo settings. Click Connect Klaviyo to reconnect.
Notify Me Campaigns need the one-click connection. They don’t show on stores using the legacy fields below.
GoodNative support may send you a link that skips steps 1-3. Install Bloom first, then open the link while logged in to Shopify admin. It goes straight to Klaviyo’s consent screen: https://admin.shopify.com/store/<store>/apps/bloom-good-native/app/notifyMe/settings?tab=klaviyo.api&klaviyo=connect <store> is your store’s handle, as it appears in your Shopify admin URL. If Klaviyo is already connected, the link just opens the Klaviyo settings. After Klaviyo you land back on the same settings panel. A successful connection shows a Klaviyo connected toast. Choosing not to allow access shows Klaviyo permissions declined, and any other failure shows Klaviyo couldn’t be connected. Try again. Both have a retry button. Then pick your list as in steps 5-6.

​
Next: set up the flow

Connecting Klaviyo means sign-ups will land in your list - but Klaviyo won’t send anything until you configure the back-in-stock flow. See Set up the back-in-stock flow.

​
Legacy connection

Before one-click connect, stores pasted two values from Klaviyo by hand. The fields are still there, further down the same Klaviyo integration panel. Bloom only uses them when Klaviyo is not connected above.
The legacy Company ID and List ID are being deprecated. Connect Klaviyo with one-click OAuth instead.
  • Company ID (Public API Key) [Legacy] - your Klaviyo site’s Public API Key (a short identifier, e.g. AbCd12). Bloom uses it from the storefront to submit sign-ups. No private API key is required.
  • List ID [Legacy] - the Klaviyo list new sign-ups are added to. Required on legacy connections - Notify Me doesn’t load without it.

​
Find your Company ID

  1. Open your Klaviyo account.
  2. Go to Settings → Account → API Keys.
  3. Copy the Public API Key - typically 6 characters. QAcpv2 in the example below.

​
Find your List ID

  4. Paste your list ID into List ID [Legacy].
  5. Click Save.
