Webex Contact Center APIs use OAuth 2.0 for authentication and authorization. Cisco's developer documentation for Webex and Webex Contact Center describes integrations as the mechanism used to request permission and obtain access tokens for API calls, using the OAuth 2.0 authorization framework rather than static API keys or basic HTTP authentication. OAuth 2.0 gives the platform scoped access control, token issuance, and administrative consent behavior appropriate for enterprise automation. Mutual TLS may be used in specific transport-security or trunking contexts, but it is not the authorization specification for normal Webex Contact Center REST APIs. Basic HTTP authentication would require sharing credentials directly with the client and does not match the Webex developer model. API key authentication is also not the supported authorization pattern for these Contact Center APIs. The typo in the original option has been corrected to OAuth 2.0.

The least privileged role that satisfies both capabilities is Supervisor. The user must participate in telephone campaigns and must also speak to an agent without the customer hearing, which is supervisor whisper coaching. Standard and Premium Agent roles can handle assigned interactions based on license capabilities, but they do not provide supervisory monitoring, whisper coaching, barge-in, or team oversight controls. An Administrator role would provide much broader configuration authority than needed, violating the least-privilege requirement. Cisco's Contact Center licensing and role model separates agent capabilities from supervisor capabilities; Premium Agent adds additional digital and reporting capabilities, while Supervisor adds monitoring and assistance functions. Whisper coaching is specifically a supervisor call-monitoring function, not a standard agent function. Because the scenario does not require tenant configuration, user provisioning, routing setup, or recording policy administration, Administrator is excessive. Supervisor is the minimal role that gives the monitoring feature while also supporting campaign participation.

Control Hub normalizes Webex Calling and Webex Contact Center numbers into E.164 format, and Cisco's voice channel setup guidance explains that numbers routed from Cloud Connected PSTN or Local Gateway are provisioned in +E.164 format for Control Hub. The fully qualified +1-450-783-2223 format is therefore valid. Cisco interfaces also accept common national display formatting for number entry in many workflows, such as parentheses around the area code, which corresponds to (450) 783-2223 in the option set. The bracketed version, hash-prefixed value, and dotted format are not acceptable telephony number formats for configuring a Webex Contact Center entry point number. The key is that the number must represent a valid PSTN telephone number that Control Hub can store and map to the entry point. The +E.164 version is the canonical final representation; the national style is an accepted entry/display form.

Cisco documents two places where skill requirements can be applied for skill-based routing in Webex Contact Center: on the queue and in the flow. Assigning skills to a queue creates fixed skill criteria for contacts that enter that queue. Assigning skills in a flow lets the flow set or adjust the skill requirements dynamically each time the Queue Contact activity is used. The screenshot shows Agent X with a skill profile and skill proficiencies; those are agent-side attributes. Routing criteria must be defined on the contact-routing side so the platform knows which agent skill profile qualifies for the contact. Desktop profiles, channels, and generic capacity-based teams do not define the skill criteria used to match this agent. Capacity-based teams are typically used for destinations that are not individual Webex Contact Center agents. Therefore, the two valid configuration locations are the queue skill settings and the flow-based skill assignment.

SMS-based one-time passcode authentication requires generating the passcode and sending it to the user over SMS. Webex Connect includes a Generate OTP node for creating the random passcode and an SMS node for delivering the generated value to the customer's mobile number. Those two nodes form the minimum authentication workflow. A Profile node can retrieve or update customer profile information but does not generate or deliver the passcode. A Data Parser node can parse structured responses, which is useful after API calls, but it is not required to create and transmit an OTP. An Evaluate node can compare the customer's submitted passcode to the stored/generated value later in the flow, but the question asks which two nodes are needed to implement authentication via SMS using a randomly generated passcode. The foundational nodes are Generate OTP and SMS. Reference: Webex Connect Help, Generate OTP node; SMS Node; Webex Connect flow builder documentation.
