Only this integration code is supported today. Requires Marketplace monitoring enabled. Full examples: Create entity — Gueno example.

Gueno sanctions monitoring (company)

{
  "type": "company",
  "externalId": "co_screening_001",
  "name": "Tech Solutions S.A.",
  "countryCode": "AR",
  "taxId": "30-71000001-2",
  "entityData": {
    "company": {
      "legalName": "Tech Solutions S.A.",
      "tradeName": "Tech Solutions",
      "industry": "Software"
    }
  },
  "monitoring": {
    "main": {
      "global_gueno_sanctions_enrichment": true
    }
  },
  "autoExecuteIntegrations": {
    "executeAllActiveEnrichments": false,
    "executeAllActiveChecks": false,
    "enrichments": ["global_gueno_sanctions_enrichment"],
    "checks": []
  }
}

Company Entity Data Structure

The entityData.company object should contain:

{
  "company": {
    "legalName": "string",
    "tradeName": "string",
    "incorporationDate": "YYYY-MM-DD",
    "companySubtype": "merchant | investment_fund | holding | bank | payment_processor | other",
    "industry": "string",
    "websiteUrl": "string",
    "employeeCount": number,
    "revenue": number,
    "revenueCurrency": "string",
    "contactInfo": {
      "email": "string",
      "phone": "string",
      "alternativePhone": "string"
    },
    "address": "string | object (see Address Format note)",
    "city": "string",
    "state": "string",
    "country": "string",
    "postalCode": "string"
  }
}

Address Format: The address field supports both formats:

String format (simple): "Av. Paulista, 1000, São Paulo, SP, Brazil"

Object format (structured):

{
  "street": "Av. Paulista",
  "number": "1000",
  "complement": "Suite 200",
  "neighborhood": "Bela Vista",
  "city": "São Paulo",
  "state": "SP",
  "country": "Brazil",
  "postalCode": "01310-100"
}

Risk Matrix Execution

You can automatically execute a risk matrix (KYB compliance rules) when creating a company by providing the riskMatrixId parameter.

How It Works

Get your Risk Matrix ID from the gu1 dashboard (format: UUID)
Include riskMatrixId in your creation request
The system will:
- Create the company entity
- Execute all KYB rules in the matrix
- Calculate risk score
- Generate compliance alerts if needed
- Update company status based on results

Example with Risk Matrix

{
  "type": "company",
  "name": "Tech Solutions S.A.",
  "taxId": "30-12345678-9",
  "countryCode": "AR",
  "riskMatrixId": "550e8400-e29b-41d4-a716-446655440000",
  "entityData": {
    "company": {
      "legalName": "Tech Solutions S.A.",
      "industry": "fintech",
      "revenue": 5000000
    }
  }
}

Combined with Enrichments

For best results, combine matrix execution with automatic enrichments:

{
  "type": "company",
  "name": "Tech Solutions S.A.",
  "taxId": "30-12345678-9",
  "countryCode": "AR",
  "riskMatrixId": "550e8400-e29b-41d4-a716-446655440000",
  "autoExecuteIntegrations": {
    "enrichments": [
      "ar_nosis_extended_verification_enrichment",
      "ar_bcra_deudas_enrichment"
    ],
    "checks": [
      "ar_repet_entity_check",
      "global_complyadvantage_sanctions_check"
    ]
  },
  "entityData": {
    "company": {
      "legalName": "Tech Solutions S.A.",
      "industry": "fintech"
    }
  }
}

Execution Flow:

Company entity created
Configured enrichments run (e.g. ar_nosis_extended_verification_enrichment, ar_bcra_deudas_enrichment)
Configured checks run (e.g. ar_repet_entity_check, global_complyadvantage_sanctions_check)
Risk matrix rules evaluate collected data
Final risk score calculated
Compliance alerts generated if rules trigger

Response

success

boolean

Indicates if the company was created successfully

entity

object

The created company object including:

id - gu1’s internal ID
externalId - Your external ID
organizationId - Your organization ID
type - Always “company”
name - Company name
riskScore - Initial risk score (0-100)
status - Company status
entityData - Company-specific data
attributes - Custom attributes
createdAt - Creation timestamp
updatedAt - Last update timestamp

rulesResult

object

Result of rules execution (only present when rules ran, e.g. when skipRulesExecution is false and a risk matrix is configured), including:

success (boolean) - Whether rules executed successfully
rulesTriggered (number) - Number of rules that were triggered
alerts (array) - Alerts generated by rules
riskScore (number) - Final calculated risk score
decision (string) - Final decision (APPROVE, REJECT, HOLD, REVIEW_REQUIRED)
rulesExecutionSummary (object) - Present when rules ran. See below for structure.

rulesExecutionSummary

object

At the root of the response (same as transactions API). Same value as rulesResult.rulesExecutionSummary. Only present when rules ran (e.g. skipRulesExecution is false). Summary of which rules matched (hit) vs did not match (no hit), executed actions, and total score. Omitted when rules did not run.

rulesHit (array) - Rules whose conditions were met. Each item: name, description, score, priority, category, status (e.g. active, shadow), conditions (array of { field, value, operator? }), actions (alerts, suggestion, status, assignedUser).
rulesNoHit (array) - Rules that were evaluated but conditions were not met. Same structure as rulesHit (includes configured actions, not executed).
actionsExecuted (object) - Aggregated executed actions across all rules that hit: alerts, suggestion (BLOCK | SUSPEND | FLAG, highest weight), status (entity status applied, if any), assignedUser ({ userId }, if any), customKeys (array of strings, optional) — custom action keys from matched rules; for integrations/workflows.
totalScore (number) - Sum of score of all rules that hit and are not in shadow status.
