Just noticed that my Python script fails when creating a new outbound contact list via the Genesys Cloud API. I am using the standard POST request to /api/v2/outbound/contactlists with a valid OAuth2 token.
The request body includes the required fields like name, status, and contactListId. However, the response consistently returns a 400 Bad Request with the error code INVALID_VALUE. The error message specifically points to contactListId.
I have verified that the token has the outbound:contactlist:write scope. Should the contactListId be omitted during creation, or does it need to match a specific UUID format? The documentation is unclear on whether this field is generated server-side or client-side during the initial POST.
Have you tried removing the contactListId field from your POST payload entirely? The INVALID_VALUE error typically occurs when the client attempts to supply an immutable system-generated identifier during resource creation. In Genesys Cloud, the contactListId is assigned server-side upon successful creation; including it in the request body violates the API contract for the POST /api/v2/outbound/contactlists endpoint. Here is a corrected Python snippet using requests that demonstrates the proper payload structure. Note that the status field must be set to "ACTIVE" or "INACTIVE" explicitly, and the name must be unique within your organization.
import requests
import base64
# Assume you already have a valid OAuth2 token
headers = {
"Authorization": "Bearer YOUR_ACCESS_TOKEN",
"Content-Type": "application/json"
}
# Correct payload: NO contactListId
payload = {
"name": "Test Contact List Jupyter",
"status": "ACTIVE",
"columnDefinitions": [
{
"name": "phone",
"type": "phone",
"required": True
},
{
"name": "email",
"type": "email",
"required": False
}
]
}
response = requests.post(
"https://api.mypurecloud.com/api/v2/outbound/contactlists",
headers=headers,
json=payload
)
if response.status_code == 201:
print("Contact list created successfully.")
print("Assigned ID:", response.json().get("id"))
else:
print(f"Failed: {response.status_code}")
print(response.json())
In my exploratory notebooks, I often use pandas to validate the columnDefinitions array against my raw CSV data before sending this request. This prevents downstream errors when uploading contacts. Ensure your OAuth token includes the outbound:contactlist:write scope; missing scopes usually return 403 Forbidden, but malformed payloads return 400. Double-check that your name does not contain special characters that might be rejected by the validator.
TL;DR: Confirming that removing contactListId from the payload resolves the 400 error. The server generates this UUID upon creation.
If I remember correctly, this is a standard pattern across the Genesys Cloud REST API, not just for Outbound. When creating resources via POST, the client must never supply the primary key identifier. The API treats the presence of a pre-existing id field as an attempt to override system integrity, hence the INVALID_VALUE response.
In the context of an Angular service using the @genesyscloud/genesyscloud-rest-client-sdk, this translates to ensuring the ContactList model passed to the method excludes the identifier. Here is how I structure the payload in my enterprise agent desktop applications to avoid this issue:
import { OutboundApi } from '@genesyscloud/genesyscloud-rest-client-sdk';
export class OutboundService {
constructor(private outboundApi: OutboundApi) {}
createContactList(name: string, status: string) {
// Explicitly omit contactListId
const payload: OutboundApi.ContactList = {
name: name,
status: status,
description: 'Created via Angular Service',
// Do NOT include: contactListId
};
return this.outboundApi.postOutboundContactlists(payload);
}
}
The suggestion above is correct. You should also verify that the status field matches the allowed enumeration values (queued, inprogress, completed, etc.), as an invalid status can sometimes mask as a general validation error depending on the SDK version’s strictness.
I have encountered similar 400 errors when attempting to update routingAttributes without properly mapping them to the RoutingAttribute object structure. Always check the Swagger definition for the specific endpoint to see which fields are marked as readOnly or writeOnly. For POST /api/v2/outbound/contactlists, the id is strictly read-only from the client perspective.
This approach ensures consistency with the API contract and prevents unnecessary retry logic in your Python script.
The documentation actually says client-supplied IDs are strictly forbidden on creation endpoints. Removing contactListId aligns with the immutable server-side generation pattern seen across the outbound API. In Architect expressions, we handle this by referencing the execution context rather than forcing static identifiers.
