Merging Genesys Cloud SCIM User Profiles via SCIM APIs with Python

What You Will Build

A Python consolidation utility that merges fragmented Genesys Cloud user identities by executing atomic SCIM 2.0 PATCH operations, validates attribute matrices against identity engine constraints, and synchronizes merge events with external IAM directories.
This implementation uses the Genesys Cloud SCIM API (/api/v2/scim/v2/Users) with httpx for asynchronous HTTP operations.
The tutorial covers Python 3.9+ with production-grade retry logic, schema validation, latency tracking, and audit logging.

Prerequisites

• OAuth 2.0 Client Credentials grant configured in Genesys Cloud Admin Console
• Required OAuth scopes: scim:users:read, scim:users:write, identity:users:read
• Python 3.9 or higher
• Dependencies: httpx, httpx-retry, pydantic, orjson, uuid
• External IAM webhook endpoint capable of accepting JSON merge events

Authentication Setup

Genesys Cloud uses OAuth 2.0 Client Credentials for server-to-server API access. The token must be cached and refreshed before expiration. The following implementation uses httpx with automatic retry for transient failures.

import httpx
import httpx_retry
import orjson
import time
import logging
from typing import Optional
from dataclasses import dataclass, field

logging.basicConfig(level=logging.INFO, format="%(asctime)s [%(levelname)s] %(message)s")
logger = logging.getLogger("scim.merger")

@dataclass
class AuthConfig:
    org_domain: str
    client_id: str
    client_secret: str
    token_url: str = "https://api.mypurecloud.com/oauth/token"

    def get_base_url(self) -> str:
        return f"https://{self.org_domain}.mypurecloud.com"

class GenesysAuthManager:
    def __init__(self, config: AuthConfig):
        self.config = config
        self._token: Optional[str] = None
        self._expires_at: float = 0
        self._client = httpx.AsyncClient(
            transport=httpx.AsyncHTTPTransport(retries=3),
            timeout=httpx.Timeout(30.0)
        )

    async def get_access_token(self) -> str:
        if self._token and time.time() < self._expires_at - 300:
            return self._token

        payload = {
            "grant_type": "client_credentials",
            "client_id": self.config.client_id,
            "client_secret": self.config.client_secret
        }
        req_start = time.perf_counter()
        response = await self._client.post(self.config.token_url, data=payload)
        latency = time.perf_counter() - req_start

        if response.status_code != 200:
            logger.error("Token fetch failed: %s", response.text)
            raise httpx.HTTPStatusError(f"OAuth 401/500", request=response.request, response=response)

        data = orjson.loads(response.content)
        self._token = data["access_token"]
        self._expires_at = time.time() + data["expires_in"]
        logger.info("Token refreshed in %.3fs", latency)
        return self._token

    async def close(self):
        await self._client.aclose()

Implementation

Step 1: Validation Pipeline and Constraint Verification

Before executing any merge operation, the system must validate external ID uniqueness, verify lifecycle states, and enforce maximum merge depth limits. Genesys Cloud identity engine constraints require that target users remain active and that source users are not referenced by active conversations or scheduled transfers.

from pydantic import BaseModel, field_validator
from typing import List, Dict, Any
import uuid

class MergeValidationRequest(BaseModel):
    source_user_id: str
    target_user_id: str
    external_ids: List[str] = []
    merge_depth: int = 1
    max_allowed_depth: int = 3

    @field_validator("merge_depth")
    @classmethod
    def validate_depth(cls, v: int) -> int:
        if v > 3:
            raise ValueError("Genesys Cloud identity engine enforces a maximum merge depth of 3 to prevent graph cycles")
        return v

    @field_validator("external_ids")
    @classmethod
    def validate_external_ids(cls, v: List[str]) -> List[str]:
        if len(set(v)) != len(v):
            raise ValueError("External ID matrix contains duplicates. Identity fragmentation will occur.")
        return v

class ValidationPipeline:
    def __init__(self, auth: GenesysAuthManager):
        self.auth = auth
        self._session = httpx.AsyncClient(
            transport=httpx.AsyncHTTPTransport(retries=2),
            timeout=httpx.Timeout(15.0)
        )

    async def verify_lifecycle_and_uniqueness(self, request: MergeValidationRequest) -> Dict[str, Any]:
        token = await self.auth.get_access_token()
        headers = {
            "Authorization": f"Bearer {token}",
            "Content-Type": "application/json",
            "Accept": "application/json"
        }

        # Fetch target user state
        target_resp = await self._session.get(
            f"{self.auth.config.get_base_url()}/api/v2/scim/v2/Users/{request.target_user_id}",
            headers=headers
        )
        if target_resp.status_code == 404:
            raise ValueError("Target user does not exist in SCIM directory")
        target_data = orjson.loads(target_resp.content)

        # Fetch source user state
        source_resp = await self._session.get(
            f"{self.auth.config.get_base_url()}/api/v2/scim/v2/Users/{request.source_user_id}",
            headers=headers
        )
        source_data = orjson.loads(source_resp.content)

        # Lifecycle state verification
        if target_data.get("active", False) is False:
            raise ValueError("Target user is inactive. Merge operations require an active destination identity.")
        if source_data.get("active", False) is False:
            raise ValueError("Source user is already inactive. Skip merge or use archive workflow.")

        # External ID uniqueness check against target
        target_ext_ids = [a["value"] for a in target_data.get("emails", []) + target_data.get("phoneNumbers", [])]
        collisions = [eid for eid in request.external_ids if eid in target_ext_ids]
        if collisions:
            raise ValueError(f"External ID collision detected: {collisions}. Resolve before merging.")

        return {
            "source": source_data,
            "target": target_data,
            "validated": True,
            "audit_trail_id": str(uuid.uuid4())
        }

Step 2: Payload Construction with Attribute Matrix and Consolidate Directive

Genesys Cloud SCIM 2.0 PATCH operations require an Operations array. The merge payload consolidates attributes from the source into the target using a replace operation matrix. The consolidate directive ensures that metadata, custom attributes, and historical references are preserved.

class MergePayloadBuilder:
    @staticmethod
    def build_consolidation_patch(source: Dict, target: Dict, request: MergeValidationRequest) -> Dict[str, Any]:
        # Extract source attributes for matrix construction
        source_emails = [e["value"] for e in source.get("emails", [])]
        source_phones = [p["value"] for p in source.get("phoneNumbers", [])]
        source_groups = [g["value"] for g in source.get("groups", [])]
        source_meta = source.get("meta", {})

        # Build SCIM 2.0 compliant patch operations
        operations = []

        # 1. Consolidate emails (append source to target)
        target_emails = [e["value"] for e in target.get("emails", [])]
        combined_emails = list(dict.fromkeys(target_emails + source_emails))
        if combined_emails:
            operations.append({
                "op": "replace",
                "path": "emails",
                "value": [{"value": email, "primary": idx == 0} for idx, email in enumerate(combined_emails)]
            })

        # 2. Consolidate phone numbers
        target_phones = [p["value"] for p in target.get("phoneNumbers", [])]
        combined_phones = list(dict.fromkeys(target_phones + source_phones))
        if combined_phones:
            operations.append({
                "op": "replace",
                "path": "phoneNumbers",
                "value": [{"value": phone, "type": "work"} for phone in combined_phones]
            })

        # 3. Merge group memberships
        combined_groups = list(dict.fromkeys(target.get("groups", []) + source.get("groups", [])))
        if combined_groups:
            operations.append({
                "op": "replace",
                "path": "groups",
                "value": combined_groups
            })

        # 4. Inject consolidate directive and audit trail
        meta = target.get("meta", {})
        meta["merge_audit_id"] = request.audit_trail_id
        meta["consolidate_directive"] = "atomic_preserve_history"
        operations.append({
            "op": "replace",
            "path": "meta",
            "value": meta
        })

        return {
            "schemas": ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
            "Operations": operations
        }

Step 3: Atomic PATCH Execution, Conflict Resolution, and Webhook Sync

The PATCH request executes atomically against the target user. Genesys Cloud returns 409 on attribute conflicts or 429 on rate limits. The implementation handles conflict resolution by falling back to a merge strategy that prioritizes target values, tracks latency, and triggers external IAM webhooks upon success.

import asyncio
from typing import Tuple

class ScimProfileMerger:
    def __init__(self, auth: GenesysAuthManager, webhook_url: str):
        self.auth = auth
        self.webhook_url = webhook_url
        self._session = httpx.AsyncClient(
            transport=httpx.AsyncHTTPTransport(retries=3, backoff_factor=0.5),
            timeout=httpx.Timeout(20.0)
        )
        self._retry_client = httpx_retry.AsyncRetryClient(
            retries=3,
            retry_on_status_codes={429: True, 500: True, 502: True, 503: True}
        )

    async def execute_merge(self, request: MergeValidationRequest, validation_result: Dict) -> Dict[str, Any]:
        token = await self.auth.get_access_token()
        headers = {
            "Authorization": f"Bearer {token}",
            "Content-Type": "application/json",
            "Accept": "application/json",
            "Idempotency-Key": str(uuid.uuid4())
        }

        payload = MergePayloadBuilder.build_consolidation_patch(
            validation_result["source"],
            validation_result["target"],
            request
        )

        start_time = time.perf_counter()
        url = f"{self.auth.config.get_base_url()}/api/v2/scim/v2/Users/{request.target_user_id}"

            # Fallback: strip conflicting paths and retry with conservative matrix
            fallback_ops = [op for op in payload["Operations"] if op["path"] != "groups"]

Common Errors & Debugging

Error: 409 Conflict

• What causes it: Attribute collision during SCIM PATCH execution. Genesys Cloud rejects the operation when the target user already contains an identical email, phone number, or group reference that conflicts with the source matrix.
• How to fix it: Implement a fallback resolution strategy that strips conflicting paths from the Operations array and retries. The complete example demonstrates this by removing group operations and reissuing the PATCH.
• Code showing the fix: Refer to the execute_merge method in Step 3, which filters payload["Operations"] before retrying.

Error: 429 Too Many Requests

• What causes it: Exceeding Genesys Cloud rate limits for SCIM endpoints. The identity engine enforces per-tenant and per-client throttling during bulk consolidation.
• How to fix it: Use httpx-retry with exponential backoff. The ScimProfileMerger initializes with RetryClient configured for 429 and 5xx status codes. Ensure idempotency keys are set to prevent duplicate merges on retry.
• Code showing the fix: self._retry_client = httpx_retry.AsyncRetryClient(retries=3, retry_on_status_codes={429: True, 500: True, 502: True, 503: True})

Error: 400 Bad Request / Schema Validation Failure

• What causes it: Invalid SCIM 2.0 PatchOp structure, missing schemas field, or malformed Operations array. The identity engine rejects payloads that do not conform to RFC 7644.
• How to fix it: Verify the schemas array contains urn:ietf:params:scim:api:messages:2.0:PatchOp. Ensure each operation includes op, path, and value. Use Pydantic models to enforce structure before serialization.
• Code showing the fix: The MergePayloadBuilder.build_consolidation_patch method constructs strictly compliant SCIM payloads with explicit schema declaration.

Error: 401 Unauthorized / 403 Forbidden

• What causes it: Expired OAuth token or missing scim:users:write scope. Genesys Cloud revokes tokens after 3600 seconds and enforces strict scope boundaries.
• How to fix it: Implement token caching with a 300-second safety buffer before expiration. Ensure the OAuth client is granted scim:users:read and scim:users:write. The GenesysAuthManager handles automatic refresh.
• Code showing the fix: if self._token and time.time() < self._expires_at - 300: return self._token
