Inventory Manager API · products

The product a SKU belongs to, by the SKU of one of its variants

GET /variants/{sku}

Any one of these scopes is enough.

How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.

AI agent tool

Agents call this as catalog_get_variant (Catalog: Get variant), in the catalog toolset. It only reads.

Connecting an agent: AI agents.

The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: inventory-manager.openapi.json. Base URL https://inventory.getmanifold.io.

Errors

Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.

`401`

Refusal	What it means	What to do
`Unauthorized` reason	The token is missing, expired or not one Manifold issued.	Get a fresh token and send the call again.
`TokenAlreadyUsed` tokenId	A single-use app token was already spent.	Mint a new token for this call.

`402`

Refusal	What it means	What to do
`SubscriptionRequired` status	The organization's subscription has lapsed, so writes are refused.	An owner settles billing. Reads still work meanwhile.

`403`

Refusal	What it means	What to do
`TenantRequired` userId	The token names no organization.	Choose the organization, then get a new token.
`ScopeRequired` required	The token's roles do not grant the scope this call needs.	Ask an owner or admin for a role that grants it.

`404`

Refusal	What it means	What to do
`VariantNotFound` sku	No such record in this organization.	Check the id in the path or the body.

`409`

Refusal	What it means	What to do
`MirroredFromSource` source	This area is fed by your source system until the organization goes live.	Make the change in the source system, or go live first.

`503`

Refusal	What it means	What to do
`RequestLogUnavailable` tokenId, reason	The service could not record the request, so it did nothing.	Try again shortly.
