Provides access to information about profiles and contacts.

MetaPub collects, normalizes and distributes publicly available program, episode, and piece metadata through the public radio system. Backed by ContentDepot and its data model, MetaPub allows producers to supply metadata through various methods:
MetaPub Agents that collect producer metadata by "crawling" existing public feeds (e.g. C24, BBC) or the producer's production system (e.g. ATC, ME, TED Radio Hour).
Manually enter metadata in the ContentDepot Portal on each program and episode.
Publish/push the metadata to the MetaPub upload API and execute an ingest job.
MetaPub then distributes this data to stations through an electronic program guide (EPG model)
for display on various listener devices such as smart phones, tablets, web streams, HD radios, RDBS enabled FM radios, and more. The EPG format is based on the RadioDNS specifications.
RadioDNS and MetaPub
The RadioDNS Service and Programme Information Specification (TS 102 818 v3.1.1) defines three primary documents: Service Information, Program Information, and Group Information. These documents, along with the core RadioDNS Hybrid Lookup for Radio Services Specification (TS 103 270 v1.2.1) define a system where an end listener device can dynamically discover program metadata and fetch the metadata via Internet Protocol (IP) requests. MetaPub's use of RadioDNS differs slightly in that MetaPub (a.k.a PRSS) acts as the "service provider" while the stations and related middleware act as the end devices. While this is not the primary use case of RadioDNS, the flexibility in the specification, service definitions, and DNS resolution allows this model to be easily represented.
This documentation gives a high level overview of how the RadioDNS specifications will be used by MetaPub, however it is strongly recommended that the related RadioDNS specifications be read for implementation details, definitions, and required XML schemas.
ContentDepot Drive
ContentDepot Drive (CD Drive) provides a private, per customer file storage solution similar to other cloud storage solutions such as Google Drive, Box, and Dropbox. The CD Drive is used to stage content uploads such as metadata files, images, or segment audio before associating the content with specific programs or episodes.
CD Drive content can be referenced using a URI by some operations such as synchronizing metadata. There are two possible CD Drive URI formats supported: ID and hierarchical path. The ID reference takes the form . More information about URIs can be found at Wikipedia.
Authentication
The API currently uses OAuth 2.0. Some operations require specific scopes to limit clients while the ContentDepot backend may also enforce existing user specific permissions.

The My Business Business Calls API manages business calls information of a location on Google and collect insights like the number of missed calls to their location. Additional information about Business calls can be found at https://support.google.com/business/answer/9688285?p=callhistory. If the Google Business Profile links to a Google Ads account and call history is turned on, calls that last longer than a specific time, and that can be attributed to an ad interaction, will show in the linked Google Ads account under the "Calls from Ads" conversion. If smart bidding and call conversions are used in the optimization strategy, there could be a change in ad spend. Learn more about smart bidding. To view and perform actions on a location's calls, you need to be a OWNER, COOWNER or MANAGER of the location.

The Resource Settings API allows users to control and modify the behavior of their GCP resources (e.g., VM, firewall, Project, etc.) across the Cloud Resource Hierarchy.
