Integrate Caller ID Name (CNAM)

Learn how to call the RiskOS™ Evaluation API with Caller ID Name (CNAM) to retrieve and verify registered names for U.S. phone numbers.

Before you start

Make sure your RiskOS™ environment is provisioned with:

A workflow configured for the CNAM enrichment.

Regional support coverage for the CNAM enrichment (US phone numbers only).

Choose your environment

Start with Sandbox for development and testing, then move to Production for live applications.

No real customer data
Free testing environment
Unlimited API calls

Get an API key

In the Sandbox RiskOS™ Dashboard, go to Developer Workbench > API Keys.
Copy your API key securely.

How it works

Add CNAM as an enrichment in your RiskOS™ workflow.
Send a POST request to /api/evaluation with the phone number (E.164 format).
Socure queries telecom CNAM sources and returns registered caller identity details.
Use CNAM results (e.g., callerName, callerType) to enhance decisioning and routing.

Common integration patterns

The table below outlines common CNAM use cases and expected outcomes.

Use Case	Required Inputs	Response Fields	Example Outcome
Identity verification	`phone_number`	`callerName`, `callerType`	Match user-provided vs. CNAM record
Fraud detection (VoIP mismatch)	`phone_number`	`callerName`, `valid`	Flag when CNAM missing or invalid
Case management / audit trails	`phone_number`	`callerName`, `countryCode`	Log CNAM results with evaluation

Request schema

Top-level fields

Field	Type	Required	Description	Example
`id`	String	Required	Required, customer-defined unique identifier for the request. This value must be unique for each evaluation. Reusing an ID causes RiskOS™ to treat the request as a re-run and can impact processing behavior, results, and downstream workflows.	`"APP-12345"`
`timestamp`	String	Required	RFC 3339 timestamp when the request was made.	`"2025-09-30T08:15:30.456Z"`
`workflow`	String	Required	RiskOS™ workflow name configured in your environment. Note: The workflow name must be unique within your RiskOS™ environment. It is not scoped by use case and must identify a single active workflow for each Evaluation API request.	`"consumer_onboarding"`
`data`	Object	Required	Main payload containing business and individual information	See `data` schema below.
→`individual`	Object	Required	Primary identity object containing individual's information.
→`individual.phone_number`	String	Required	Phone number in E.164 format (U.S. only). The API expects the standard E.164 format (e.g., +12025550147) but tolerates hyphens and spaces for user convenience.	`"+14155551212"`

Example response

When you call the Evaluation API, RiskOS™ returns a JSON payload that includes the final decision, evaluation metadata, and enrichment-specific results.

Key response fields

RiskOS™ returns a consistent set of top-level fields that describe the outcome of an evaluation, along with enrichment-specific results that depend on your workflow configuration.

Where to find specific results

Area	Fields	How to use it
Decision and routing	`decision`, `decision_at`, `tags`, `review_queues`, `notes`, `score`	Primary control signals. Branch application logic using `decision`. Use tags, queues, notes, and score for secondary routing, review, and explanation.
Module results	Module-specific fields (for example: `reasonCodes`, scores, extracted attributes)	Evidence and signals produced by workflow modules. Use for escalation, compliance review, investigation, and audit.
Identifiers and traceability	`id`, `eval_id`	Persist these identifiers to correlate API calls, logs, webhooks, GET requests, and support cases.
Enrichment execution	`data_enrichments[]` (`response`, `status_code`, `total_attempts`, `is_source_cache`)	Inspect enrichment outputs and detect provisioning issues, partial failures, retries, or cached responses.
Workflow context	`workflow`, `workflow_id`, `workflow_version`	Understand which workflow ran and which version produced the result. Useful for debugging and historical analysis.
Evaluation lifecycle	`eval_status`, `status`, `sub_status`	Execution and case state only. Useful for monitoring and asynchronous workflows. Do not use for business decisions.
Execution context	`eval_source`, `eval_start_time`, `eval_end_time`, `environment_name`	Observability and performance metadata for latency tracking, environment validation, and API vs Dashboard attribution.

Decision and routing (primary control signals)

Use these fields to determine what action your application should take.

decision values are workflow-specific and may differ from the examples shown in this guide.

Field	Type	Description	Example
`decision`	String (enum)	Final evaluation result. Possible values: • `ACCEPT` • `REVIEW` • `REJECT` Note: The fields returned can be customized to fit your integration or business needs.	`"REVIEW"`
`decision_at`	String `<Date-Time>`	RFC 3339 timestamp when the decision was finalized.	`"2025-09-30T08:15:31.102Z"`
`score`	Number	If configured for a workflow, provides an aggregate score of all steps. This can be used for risk banding, additional routing, or analytics alongside the primary `decision` value.	`0.87`
`tags`	Array of Strings	Array of labels applied during the workflow to highlight routing choices, notable signals, or rule outcomes. Useful for reporting, segmentation, or UI highlighting in the RiskOS™ Dashboard.	`["name_phone_mismatch"]`
`review_queues`	Array of Strings	Lists any manual review queues the evaluation was sent to. Empty when the case is fully auto-resolved without human review.	`["kyc-us"]`
`notes`	String	Freeform text field for analyst or system comments about the evaluation. Often used to capture manual review rationale or investigation context.	`"CNAM result requires verification"`

Evaluation lifecycle and status

These fields describe where the evaluation is in its lifecycle and are useful for monitoring and asynchronous workflows.

Field	Type	Description	Example
`eval_status`	String (enum)	Indicates the current state of an evaluation in RiskOS™. Possible values: • `evaluation_completed` • `evaluation_paused` • `evaluation_in_progress`	`"evaluation_completed"`
`status`	String (enum)	Indicates the current state of an evaluation or case. Possible values: • `OPEN` • `CLOSED`	`"CLOSED"`
`sub_status`	String	Provides additional detail about the evaluation status. Example values: • `Under Review` • `Pending Verification` • `Accept` • `Reject`	`"Under Review"`

Identifiers and traceability

Use these fields to correlate requests, logs, webhooks, and support cases.

Field	Type	Description	Example
`id`	String (UUID or custom string)	Your evaluation identifier within RiskOS™. Note: This is customer-generated.	`"APP-123456"`
`eval_id`	String (UUID)	RiskOS™-generated unique identifier for the evaluation.	`"91a6a0a8-5c4a-4f5a-93f0-1f3e78e2f9c1"`
`workflow`	String	Name of the workflow executed.	`"consumer_onboarding"`
`workflow_id`	String (UUID)	Unique identifier for the workflow run.	`"e87f4f3b-9d6c-4e3b-bdf6-8df94c3d8a01"`
`workflow_version`	String	Version of the executed workflow.	`"41.2.0"`

Execution context

These fields provide timing and environment context for the evaluation.

Field	Type	Description	Example
`eval_source`	String (enum)	Indicates where the evaluation was initiated from. Possible values: • `API`: Request submitted via the Evaluation API. • `Dashboard`: Case created or evaluated through the RiskOS™ Dashboard.	`"API"`
`eval_start_time`	String `<Date-Time>`	RFC 3339 timestamp for when RiskOS™ started processing the evaluation. Useful for latency and performance monitoring.	`"2025-09-30T08:15:30.982Z"`
`eval_end_time`	String `<Date-Time>`	RFC 3339 timestamp for when RiskOS™ finished processing the evaluation. Can be paired with `eval_start_time` to compute total processing time.	`"2025-09-30T08:15:31.215Z"`
`environment_name`	String	Indicates which environment the evaluation ran in. Typically `Sandbox` for testing or `Production` for live traffic.	`"Sandbox"`

Best practices for integration and maintenance

Always validate phone_number inputs in E.164 format.
Use sandbox mode and known test numbers during QA.
Log CNAM responses for audit trails.
Apply routing when CNAM mismatches the user-provided name.
Monitor coverage variations (especially VoIP lines).

Validation checklist

Test coverage

Known valid numbers → PASS

Invalid or unrecognized numbers → FAIL or REVIEW

Schema and error handling

Fields match schema across environments

Errors are structured and retryable

Logging and observability

Log full request/response with correlation IDs

Redact API keys and secrets
