To fetch a catalog item, use the catalogItem method. This method requires a credentialToken and a variables object containing the id or the productId, and sku of the catalog item you want to retrieve.

#### Example:

`typescript
const variables = {
id: 'catalog_item_7a628c98-9ded-48c8-8831-b227f919e25d',
productId: 'test',
sku: 'test',
};

const { json, errors } = await zonosClient.catalogItem({
credentialToken,
variables,
});
`

#### Zonos Graph Documentation:

For more details on the catalogItem query and its parameters, visit the Query.catalogItem documentation.

To classify an item, use the classificationsCalculate method. This method requires a credentialToken and a variables object containing the inputs array. Each item in the inputs array should have a name property.

#### Example:

`typescript
const variables = {
inputs: [{ name: 'backpack' }],
};

const { json, errors } = await zonosClient.classificationsCalculate({
credentialToken,
variables,
});
`

To calculate the full landed cost of items, use the fullLandedCost method. This method requires a credentialToken and a variables object containing the itemCreateWorkflowInput array, the landedCostCalculateWorkflowInput object, and the partyCreateWorkflowInput array.

#### Example:

`typescript
const variables = {
itemCreateWorkflowInput: [
{
amount: 20,
countryOfOrigin: 'CN',
currencyCode: 'USD',
description: 'Backpack',
hsCode: '4202.92',
productId: 'e89861c0-f04e-11ee-bc4f-4b0822420556',
quantity: 1,
},
{
amount: 1,
countryOfOrigin: 'CN',
currencyCode: 'USD',
description: 'Fancy pen',
hsCode: '4202.92',
productId: 'g12345d1-f04e-11ee-bc4f-8c1393819393',
quantity: 4,
},
],
landedCostCalculateWorkflowInput: {
calculationMethod: 'DDP',
endUse: 'NOT_FOR_RESALE',
tariffRate: 'ZONOS_PREFERRED',
},
partyCreateWorkflowInput: [
{
location: {
administrativeArea: '',
administrativeAreaCode: 'QC',
countryCode: 'CA',
line1: '4398 St Laurent av',
line2: ' ',
locality: 'Montreal',
postalCode: 'H2W 1Z5',
},
type: 'ORIGIN',
},
{
location: {
administrativeArea: '',
administrativeAreaCode: '',
countryCode: 'GB',
line1: 'location line 1',
locality: '',
postalCode: 'SW1W 0NY',
},
type: 'DESTINATION',
},
],
};

const { errors, json } = await zonosClient.fullLandedCost({
credentialToken,
variables,
});
`

To create an order from a landed cost calculation, use the orderCreate method. This method requires a credentialToken and a variables object containing the input object with the landedCostId and other order details.

#### Example:

`typescript
const variables = {
input: {
accountOrderNumber: 'order-123',
currencyCode: 'USD',
landedCostId: 'landed_cost_123',
},
};

const { errors, json } = await zonosClient.orderCreate({
credentialToken,
variables,
});
`

The Zonos Client provides methods for executing queries and mutations, and it handles the underlying HTTP requests to the Zonos API. It requires a credentialToken and a variables object as input parameters. In addition, it supports optional parameters such as customUrl, headers, and customFetch.

`typescript
/* @param credentialToken The token used to authenticate with the Zonos Graph /
credentialToken: string;
/**
* @param customFetch Optional custom fetch function to send your own request,
* or insert middleware between the generated query and the request.
/
customFetch?: typeof fetch;
/* @param customUrl Optional custom URL to use for the request instead of the built-in URL /
customUrl?: string;
/* @param headers Optional additional headers for the request /
headers?: HeadersInit;
