# Intro to runtime API calls

Runtime, or buyside, APIs are used to create, update, and save configurations.

ServiceNow CPQ APIs are divided into two categories: runtime APIs and admin APIs. In this article, we introduce the runtime APIs.

Runtime APIs are used to create, read, update, and delete configurations, and are the same APIs that are used in the ServiceNow CPQ End User Configurator. They are also commonly referred to as the “buyside“ APIs.

**Note:** For the most updated information on sample codes and other details, see [API Documentation](https://api-docs.logik.io/#introduction).

All API calls follow this base URL format: `https://<yourTenant>.<sector>.logik.io/api/`. In this URL, yourTenant represents your unique listed ServiceNow CPQ tenant name, and sector is the sector where your ServiceNow CPQ environment is located.

If you are a Salesforce user, you can find your tenant URL by clicking **Setup** in your Salesforce account. In the Quick Find box, search for or click **Custom Settings**, and then click **Manage**. Your tenant URL will be displayed.

All runtime API calls require bearer token authentication using a unique token that is available in the runtime client. They also require that the origin URL configured in the runtime client appears in the request header.

To authenticate, collect the bearer token and the origin URL from ServiceNow CPQ Admin → Utilities → Runtime Client. For each API call in a Postman, add the following header:

```
Key: Origin
Value: <yourOrigin>
```

In the Authorization tab of Postman or your API tool, select **Bearer Token**, and then input the unique token you copied from ServiceNow CPQ Admin.

## Basic runtime API calls

-   The initial configure call starts the configuration process by passing the ID of the configurable product, and returns a configuration UUID for later use.

    Example \(cURL\):

    ```
    curl -X POST https://<yourTenant>.<sector>.logik.io/api/ \
    -H "Authorization: Bearer <yourBearerToken>" \
    -H "Origin: <yourOrigin>" \
    -H "Content-Type: application/json" \
    -d '{
        "sessionContext": {
            "stateful": true
        },
        "partnerData": {
            "product": {
                "configuredProductId": "{{configProductId}}",
            }
        },
        "fields": []
    }'
    ```

    Example \(response\):

    ```
    {
      "configurationId": "{uuid}"
    ```

    You also use this API call for reconfiguring, providing a previously saved configuration UUID in the POST body.

    Example reconfigure \(cURL\):

    ```
    curl -X POST https://<yourTenant>.<sector>.logik.io/api/ \
    -H "Authorization: Bearer <yourBearerToken>" \
    -H "Origin: <yourOrigin>" \
    -H "Content-Type: application/json" \
    -d '{
        "sessionContext": {
            "stateful": true
        },
        "partnerData": {
            "product": {
                "configuredProductId": "{{configProductId}}",
                "configurationAttributes": {
                    "LGK__ConfigurationId__c": "{{uuid}}"
                }
            }
        },
        "fields": []
    }'
    ```

-   The update configuration call updates an existing configuration by passing the configuration UUID and desired field values, and returns all possible fields and their values.

    Example \(cURL\):

    ```
    curl -X PATCH https://<yourTenant>.<sector>.logik.io/api/{uuid} \
    -H "Authorization: Bearer <yourBearerToken>" \
    -H "Origin: <yourOrigin>" \
    -H "Content-Type: application/json" \
    -d '{ "fields": { "color": "blue", "size": "large" } }'
    ```

    Example \(response\):

    ```
    {
      "fields": {
        "color": "blue",
        "size": "large",
        "price": "$100"
      }
    }
    ```

-   The get BOM call passes the configuration UUID and retrieves the Bill of Materials \(BOM\) for the configuration. It returns the current BOM for the configuration.

    Example \(cURL\):

    ```
    curl -X GET https://<yourTenant>.<sector>.logik.io/api/{uuid}/bom \
    -H "Authorization: Bearer <yourBearerToken>" \
    -H "Origin: <yourOrigin>"
    ```

    Example \(response\):

    ```
    {
      "bom": [
        { "item": "componentA", "quantity": 2 },
        { "item": "componentB", "quantity": 1 }
      ]
    }
    ```

-   The save call saves the configuration in ServiceNow CPQ. This ensures that the configuration UUID can be used and reconfigured in the future.

    This process asynchronously populates our custom objects, configuration field data sets, and configuration line items in Salesforce.

    Example \(cURL\):

    ```
    curl --location --request PATCH 'https://mpanigrahi-demo.demo01.logik.io/api/6d0ef6fd-4c88-44f3-a296-b03421c369c6' \
    --header 'Content-Type: application/json' \
    --header 'Accept: application/json' \
    --header 'Origin: https://mpanigrahi-demo.demo01.logik.io' \
    --header 'Authorization: <<RUNTIME TOKEN>>' \
    --header 'Cookie: LGKSESSION=NDA5OWJmNmEtNDhhOS00YTc4LTk3ODktZTg0OGYyOGIwMjZk' \
    --data '{"fields":[{"variableName":"name_d1","value":"megha","dataType":"text"}],"responseState":{"setPagination":{"collections":{"pageSize":10,"pageNumber":0},"fields":{"pageSize":10,"pageNumber":0},"componentTypes":{"pageSize":10,"pageNumber":0}},"defaultPagination":{"pageSize":10,"pageNumber":0},"searchValues":{}}}'
    ```
