# Unmatched API extension classes

The CMDB CI Class Models app adds or updates classes for unmatched APIs. API endpoints that are not structured well enough to populate the API \[cmdb\_ci\_api\] and API Component \[cmdb\_ci\_api\_component\] classes instead populate the Unmatched API Endpoint \[cmdb\_ci\_unmatched\_api\_endpoint\] class. Unmatched APIs are typically used by integrations like security scanners or observability tools.

CMDB CI Class Models is a ServiceNow Store app that adds class models that extend the CMDB class hierarchy. The new or updated classes include class descriptions, identification rules, identifier entries, and, if applicable, dependent relationships. You can use the added classes just like any other CMDB class. Applications such as Discovery and Service Mapping Patterns can use the class extensions to populate CIs and discover technologies and software.

See the release notes for all CMDB CI class models.

## Request apps on the Store

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://www.servicenow.com/docs/r/store-release-notes/sn-store-release-notes.html).

## Unmatched APIs

API endpoints that are not structured well enough to populate the API \[cmdb\_ci\_api\] and API Component \[cmdb\_ci\_api\_component\] classes instead populate the Unmatched API Endpoint \[cmdb\_ci\_unmatched\_api\_endpoint\] class. Unmatched APIs are typically used by integrations like security scanners or observability tools.

## Classes

This section lists the classes that the CMDB CI Class Models app adds or updates.

CMDB CI Class Models: Release 1.49.0 adds the following class for unmatched API endpoints. For the list of classes in the base system, including classes that this app might extend, see [CMDB tables descriptions](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/servicenow-platform/configuration-management-database-cmdb/cmdb-tables-details.md).

</table>## Key Relationship Structures

The Unmatched API Endpoint \[cmdb\_ci\_unmatched\_api\_endpoint\] CMDB class and API Endpoint Discovered \[api\_endpoint\_discovered\] non-CMDB table are intended for scenarios where unstructured API data is ingested and needs to be processed beyond the capabilities of IntegrationHub-ETL.

API Endpoint Discovered \[api\_endpoint\_discovered\] can serve as a staging table for raw data for the API \[cmdb\_ci\_api\] and API Component \[cmdb\_ci\_api\_component\] classes. API data that does not come from a well-structured data source or cannot have standard identification rules applied can first populate the API Endpoint Discovered \[api\_endpoint\_discovered\] table. You can then use a customer-defined integration to promote that well-formed data that matches the quality and condition requirements for API \[cmdb\_ci\_api\] and API Component \[cmdb\_ci\_api\_component\] populates the most appropriate table.

In cases where the data cannot be correctly parsed or is structured in an unexpected fashion, you can instead use a customer-defined integration to populate the Unmatched API Endpoint \[cmdb\_ci\_unmatched\_api\_endpoint\] table.

Data that populates the API Endpoint Discovered \[api\_endpoint\_discovered\] table is purged every 30 days.

</table>## Related non-CMDB tables

The Unmatched API extension class uses the API Deployment \[api\_deployment\] non-CMDB table as a related list:

|Attribute|Data type|Description|
|---------|---------|-----------|
|Name|String \(100\)|Name of the API deployment.|
|API|Reference|Reference to the deployed API \(cmdb\_ci\_api\).|
|Unmatched API Endpoint|Reference|Reference to the unmatched API endpoint, if the API doesn't match an existing API \(cmdb\_ci\_unmatched\_api\_endpoint\).|
|Configuration Item|Reference|Reference to the Configuration Item. This is typically manually specified as a reference, if you know what CI the API is deployed to.|
