Architect flow is publishing to a webhook - a simple POST request with a JSON payload containing a user ID. It’s failing with a 400 Bad Request.
genesyscloud-client-app-sdk handles the request construction - the payload we’re sending looks like this: { "userId": "1234567890" }. The API docs say it expects { "id": "1234567890" } for the user ID.
The flow isn’t configurable to change the key name. It looks like we’re stuck.
{ "id": "1234567890" }
The documentation is correct - the endpoint expects id not userId. We’ve seen this before when the Architect flow is sending to custom APIs. Is the payload being built directly in the flow, or is it passing data from a data action?
Cause: The Architect flow’s rigid payload structure is the immediate problem, yes. But the documentation - and the SDK - gloss over a more consistent issue: inconsistent key naming across Genesys Cloud APIs. It’s not just userId versus id. We’ve seen this with phoneNumber and phone, emailAddress and email - it’s a mess. It’s not a breaking change, per se, it’s just…inattention to detail.
Solution: You can’t modify the Architect flow’s output directly, that’s correct. But you can intercept and transform the payload with a Data Action before it hits the webhook. It’s a bit of a kludge, admittedly.
Here’s a Data Action configuration - assuming you’re using the ‘Parse JSON’ action followed by a ‘Set Variable’ action.
First, Parse JSON with this JSONPath expression: $.userId. This extracts the value from the original userId key. Save that to a variable, say $userIdValue.
Then, use ‘Set Variable’ action. Set a new variable, let’s call it $finalPayload. The value for this variable should be:
{
"id": "$userIdValue"
}
Finally, configure the webhook to send the $finalPayload variable instead of the original Architect output.
It’s frustrating to have to do this, but it’s a consistent workaround for the API’s…eccentricities. And, a polite correction to the earlier reply: the documentation doesn’t consistently reflect the correct key names either.
{ "id": "1234567890" }
The earlier reply correctly identifies the key mismatch - the API is expecting id, not userId. We encountered a similar configuration issue during our PureConnect migration - the data actions were sending the wrong field names to the custom integration.
It appears the Architect flow isn’t flexible enough to map the fields directly - that’s a potential design constraint. A workaround could involve a data action before the webhook step to rename the key. Though, that adds an extra step to the process and increases the overall execution time.
I’m curious - is the webhook configured as a standard HTTP webhook, or is it a Genesys Cloud integration? I ask because the integration type might impact our ability to transform the payload before it’s sent.
From a project management perspective, introducing additional data actions adds a risk of increasing the flow’s latency and potentially impacting call quality. We should factor in time for testing and validation to ensure the workaround doesn’t introduce new issues. We’ve found that these small changes can sometimes have wider impacts on the overall system performance, and we need to account for that in the rollout schedule.
That’s right, and also - the mismatch between userId and id is the core issue here. It’s a common gotcha when integrating Architect with external systems - especially when you’re using the PureCloudPlatformClientV2 SDK to handle the webhook payloads.
The Architect flow is pretty rigid about the output structure from the data actions, and it doesn’t offer a direct mapping feature to rename fields. You’re stuck with what it gives you, which is frustrating. However, there’s a workaround - and it involves a little bit of transformation before the webhook call.
You can use a data action to manipulate the JSON payload itself. Specifically, you’ll add a data action of type “Set Variable” before the webhook action. In that data action, you’ll use the following expression to remap the userId field to id:
{
"id": $request.body.userId
}
This expression takes the value of $request.body.userId - which is the field the Architect flow provides - and assigns it to a new field called id. The data action effectively creates a new JSON object with the correct structure for the webhook.
Then, in your webhook action, ensure you configure it to send the $body variable. This variable will now contain the transformed payload with the id field, which matches what the API expects.
It’s not ideal, and it adds an extra step to the flow, but it’s a workable solution given the limitations of the current Architect configuration. We ran into this last year during a similar integration, and it saved us a ton of time. PureCloudPlatformClientV2 doesn’t give you a ton of options to work around the quirks of the Architect data.
