Create an API token
- Go to Settings > API Access.
- Create a token, give it a descriptive name, and select the permissions it needs.
- Copy the token value and store it somewhere safe. You won’t be able to see it again.
Rotate API keys
Rotating keys regenerates the value of every API token on your store while keeping each token’s name, permissions, and default flag intact. Use it when a key may have been exposed, when an integration partner changes, or as part of a routine security review.- Go to Settings > API Access.
- Click Rotate API keys in the page header.
- Confirm the action in the dialog.
- Copy the new token values from the tokens list and update each integration that uses them.
Configure response options
Response options control which optional data Layers includes in storefront API responses. They have their own settings page, separate from your tokens.- Go to Settings > Developer > Response Options.
- Turn on the options your storefront needs:
- Allow Out-of-Collection Dynamic Linking: Let dynamic linking place linked products at the top of a collection even when they aren’t members of it. When it’s off, linked products outside the collection are skipped. See Linking products that aren’t in the collection.
- Expose Variant Inventory: Include inventory quantity, inventory policy, and per-location inventory levels in the variant data the API returns. Turn it on if your storefront shows stock counts or hides sold-out variants. Leave it off to keep inventory data private.
- List every pickup location: Show every pickup-enabled location in the pickup location facet on every collection and search, with a count of 0 where nothing in the results is stocked there. When it’s off, the facet only lists locations that stock a matching product. See Local pickup filtering.
- Click Save.
The Expose Variant Inventory toggle used to be on the API Access page and saved as soon as you switched it. It now lives on the Response Options page and takes effect when you click Save.
Turn on Expose Variant Inventory
Storefront API tokens are used from shoppers’ browsers, so anyone who can load your storefront, including bots and competitors, can read the inventory data this option adds. Because of that, turning it on requires an explicit acknowledgement.- On the Response Options page, switch on Expose Variant Inventory.
- Read the Expose variant inventory? dialog that opens.
- Check the box confirming that you understand exact inventory levels become publicly readable and that you’re authorized to enable this for the store.
- Click Agree and enable, then click Save.
- Enabled by a team member, with when they agreed to the acknowledgement and its version.
- Enabled before acknowledgements were tracked. No agreement on record. The option was already on before Layers started recording acknowledgements.
- Disabled by a team member, with when they turned it off.
Review app connections
The App Connections table lists every OAuth app that a team member has connected to this store, such as MCP clients authorized through the Layers MCP server. Each row shows the app, the user who authorized it, and its current access.- App — the connecting app’s name and OAuth client ID, with its logo if the app supplied one.
- Connected by — the team member who authorized the connection. A connection can never exceed that user’s own access.
- Current access — the permissions the connection can currently exercise. Layers intersects the permissions the user originally granted with the permissions that user still has today. Tightening a role automatically narrows every connection it created.
- Status —
Validwhen the connection retains at least one working permission, orNo accesswhen permission changes have left the connection with nothing it can do.No accessrows are safe to revoke.
Revoke an app connection
Revoking a connection immediately cuts off the app’s access to your store. The user who originally authorized it can reconnect from their MCP client, which starts a fresh authorization with your current role permissions. Revoke a connection when the app is no longer in use, when the connection showsNo access, or when you want to force a reauthorization after a role change.
- Go to Settings > API Access.
- In the App Connections table, open the row’s actions menu and select Revoke access.
- Confirm Revoke connection in the dialog.
