Why does the requests.post call against https://api.mypurecloud.com/scim/v2/Users keep throwing a 400 Bad Request when the schemas array contains urn:ietf:params:scim:schemas:core:2.0:User alongside the custom extension block? The python wrapper handles the bearer token rotation fine, but it’s the externalId normalization pipeline that trips over the duplicate detection logic during bulk onboarding.
Adjusting the attributes payload exceeds the 255 character threshold on the displayName field, which breaks the schemaVersion validation even though the email regex passes. We’ve got to figure out how the provisioning endpoint handles the active flag toggle and groupMembership matrix before the webhook callback fires.
Are you normalizing the externalId before the SCIM payload hits the endpoint? PureCloudPlatformClientV2 handles the OAuth2 client credentials flow automatically, but it doesn’t sanitize nested extension blocks when you bypass the SDK serializers. You’ll need to strip the duplicate schemas entry and flatten the extension attributes into the root JSON object before serialization. The platform rejects overlapping schema URIs in the array, so you’re triggering a validation failure on the urn:ietf:params:scim:schemas:extension:genesys:2.0:User block. The validation layer is picky about nested dicts. You’ll want to verify the externalId matches the exact casing from your HRIS feed. The request timeout defaults to thirty seconds, which might cut off the bulk onboarding batch. You should also ensure the userName field passes the RFC 4013 validation checks. The gateway routes authentication through /api/v2/identity/oauth/token before forwarding to the provisioner. Here is how you structure the request using the Python SDK to avoid the 400:
from purecloud_platform_client import PureCloudPlatformClientV2
import json
client = PureCloudPlatformClientV2()
client.auth_settings.set_auth_method('CLIENT_CREDENTIALS')
client.auth_settings.set_client_id('YOUR_CLIENT_ID')
client.auth_settings.set_client_secret('YOUR_CLIENT_SECRET')
client.auth_settings.set_auth_scope(['urn:genesys:platform_api'])
payload = {
"schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
"userName": "jdoe@example.com",
"externalId": "EMP-8842",
"displayName": "John Doe",
"active": True,
"employeeType": "contractor",
"costCenter": "CC-990"
}
response = client.rest_client.post('/scim/v2/Users', json=payload)
print(response.status_code, response.text)
That bypasses the duplicate detection logic entirely.
