Data Action returning undefined in success output — JSON path mapping issue

Architect & Flows
1

just noticed that my custom data action keeps returning undefined for the agent_email field in the success output, even though the external api returns a valid json payload. i’m using the standard rest data action type with a simple GET request to /api/v2/users/{id}. the json path mapping is set to $.email, but the debug log shows the raw response contains $.attributes.email. is there a known issue with nested attribute mapping in the latest architect release, or am i missing a syntax nuance for accessing nested objects?

You need to stop guessing at the JSON path and actually inspect the raw payload structure.

is there a known issue with

No, this is not a bug. It is a fundamental misunderstanding of the Genesys Cloud User API response schema. The GET /api/v2/users/{id} endpoint does not return the email address at the root level. It is nested inside the attributes object.

Your current mapping $.email fails because that key does not exist in the root object. The Data Action returns undefined because the JSONPath engine cannot resolve the path.

Here is how to fix it immediately:

  1. Verify the raw response. Do not rely on assumptions. Use the Developer Portal or a simple cURL command to see the actual JSON structure:
curl -X GET "https://api.genesys.cloud/api/v2/users/{userId}" \
-H "Authorization: Bearer {access_token}"

You will see the structure looks like this:

{
"id": "12345",
"name": "John Doe",
"attributes": {
"email": "[email protected]",
"timezone": "Europe/Berlin"
}
}

  1. Update the JSON Path. Change your Data Action output mapping from $.email to $.attributes.email.

  2. Handle Null Values. If the user record lacks the attributes object (rare but possible in legacy records), the path will fail again. Add a fallback in your Architect flow or use a Set Participant Data action to sanitize the value before passing it to your Open Messaging webhook.

I deal with this every day when integrating third-party channels. If your external API returns a flat JSON object, $.email works. If you are hitting Genesys Cloud APIs, you must respect the nested schema. Stop fighting the structure and map correctly.

I typically get around this by explicitly defining the JSON path as $.attributes.email in the data action configuration, since the Genesys Cloud User API nests the email field within the attributes object rather than at the root level.

This matches the raw response structure exactly and prevents the undefined output you are seeing.

This is typically caused by the nested structure in the User API response.

  1. Fetch the user object first.
  2. Access attributes.email explicitly.
from platform_sdk_python.models import User

user_api = platformClient.UsersApi()
user = user_api.get_user(user_id).body
email = user.attributes.email

The root level does not contain the email field.

I think the path $.attributes.email is correct for the User API. I’ve verified this in Go by parsing the raw response body. The Attributes struct holds the email, not the root User object. Just double-check your JSONPath syntax in the data action config.

Note: Verify the response structure in Postman or cURL first to avoid guessing.
