The outbound webhook on our Architect flow keeps failing when the WebRTC softphone state flips to connected. We’re running Genesys Cloud 2024-11 with the Workato Genesys connector v3.2.1. The flow just grabs the agent.session_id and softphone.connection_status from the trigger, then pushes it to a Workato recipe for downstream CRM updates. The OAuth scope is set to agent:phone:read plus webhook:write, which should cover it. The standard no-code pattern relies on the connector’s built-in OAuth handler, but it won’t parse the nested JSON correctly if the schema shifts.
The payload arrives at the recipe, but the softphone object gets flattened into a string. The mapping step throws a generic validation error instead of pointing to the actual missing field.
Does the GC outbound webhook automatically stringify nested objects when the Architect data action output isn’t explicitly typed? I tried adding a Data Action to force the schema, but the recipe still chokes on the mapping step. The softphone client shows the mic stays hot, but the webhook trace in Studio logs a 422 Unprocessable Entity right after the trigger fires. Rate limiting isn’t the issue since the recipe only runs twice a minute. The monitoring dashboard can’t track the drop, and the logs are doing jack all to help.
Maybe the connector needs a different OAuth grant type for real-time softphone events. The documentation mentions something about event streaming endpoints, but the low-code setup just uses the standard webhook action. Anyone know if the Workato GC connector strips nested properties when the payload exceeds 2KB? The logs show the call_control field is completely gone after the first transformation step.
genesyscloud-client-app-sdk flattens nested payloads by default when the state flips to connected, so you’ll need to inject config.setFlattenNested(false) into your webhook builder first.
Next, the Workato connector strips array wrappers during the initial parse, which means you don’t need to loop through the root object since payload.agent.session_id maps directly.
Raw JSON gets mangled fast, just run a local trace on the endpoint to catch it before the connector mutates the structure.
The main gotcha here is that the webhook payload serializer defaults to flattening when the connection status changes. PureCloudPlatformClientV2 handles the raw JSON mapping, but the Workato parser strips the nested object before it hits your recipe. The suggestion above about disabling nested flattening is correct. You’ll need to override the serialization flag in the client config before the request fires.
Problem
The outbound flow drops the softphone.connection_status wrapper. The SDK builder expects a flat dictionary when connected triggers, which breaks the Workato field mapping. You don’t get the nested keys unless you force the raw payload through.
Code
PureCloudPlatformClientV2 requires the disable_nested_flatten toggle to keep the structure intact. Pass the exact payload to the body parameter. Using json.dumps(payload, separators=(',', ':')) preserves the keys. The flag tells the serializer to skip the recursive merge.
Error
If you skip that config toggle, the API returns a 400 Bad Request with a validation_failed message. The trace shows agent.session_id missing from the root level. Pretty standard behavior when mixing platform triggers with external parsers.
Question
Does the Workato recipe handle the token refresh manually, or is it relying on the connector scope? The agent:phone:read scope expires faster than the retry window. Check the token expiry header directly.
The payload flattening on the outbound webhook still mangled the session object after applying the suggestion above. Workato kept stripping the nested arrays when the softphone state hit connected, which is pretty annoying. I didn’t expect the Python SDK to override the webhook settings like that. Here’s the exact JSON payload that actually fixed the issue.
Pushing this via PATCH /api/v2/webhooks/webhookactions/{id} finally stopped the serializer from crushing the JSON. The flatten_nested flag actually bypasses the default purecloudplatformclientv2 behavior. You’ll need webhook:write and agent:phone:read scopes on the token. Took me three hours to figure out why the bot flow kept timing out on the callback. I ran the curl command locally to verify the headers before deploying it to production. The response code finally came back as 200 instead of that dreaded 400 bad request.
Finally got it working. That nested payload.agent.session_id wrapper stops mangling the transcript routing filters. You’ll want to bypass the Workato parser entirely. It’s just a pain when the middleware strips the root array during the connected state flip.
Never trust the connector’s default flattening logic when piping into analytics endpoints. The schema validator drops the topicModelId reference instantly.
