What’s the best way to update participant attributes for a live voice call using the Genesys Cloud Conversations API? I am building a PagerDuty integration that needs to push external metadata back to the active interaction. When I POST to /api/v2/conversations/voice/{conversationId}/participants/{participantId}, I receive a 200 OK, but the attributes do not persist in the participant.attributes object when I fetch the interaction later. Is there a specific scope requirement or a delay in propagation for live voice interactions?
Thanks for the help.
You might want to check at the specific payload structure required for the PATCH operation versus the POST operation. The endpoint /api/v2/conversations/voice/{conversationId}/participants/{participantId} typically requires a PATCH method to update existing participant data, not POST. A POST to this resource usually attempts to add a new participant, which fails silently or returns a 200 if the system interprets it as a no-op for an existing ID, but it does not merge attributes.
I have seen this issue frequently when integrating external systems like PagerDuty. The client credentials flow often uses a service account with conversation:write scope. Ensure your secret rotation in HashiCorp Vault has not invalidated the token during the test window. If the token is valid, the issue is almost certainly the HTTP verb.
Here is the correct curl command to update attributes:
curl -X PATCH "https://api.mypurecloud.com/api/v2/conversations/voice/{conversationId}/participants/{participantId}" \
-H "Authorization: Bearer {access_token}" \
-H "Content-Type: application/json" \
-d '{
"attributes": {
"pagerduty_incident_id": "INC-12345",
"priority": "critical"
}
}'
Note that you must send the full attributes object you wish to persist. Partial updates are not supported via this endpoint; you must include all existing attributes along with the new ones if you want to preserve them. If you only send the new key, previous keys may be overwritten depending on the SDK version. Verify the response body contains the updated attributes map. If it still fails, check the developer logs in the Genesys Cloud admin console for the specific interaction ID to see if a validation error is being suppressed by your client library.
