Trying to figure out the correct JSON mapping syntax for a Data Action that calls an external REST API. I’ve got the outbound call working fine, getting a 200 OK, but the response mapping is failing silently. The external API returns a nested JSON structure, and I need to pull a specific field from within that object into an Architect variable.
Here’s the Data Action JSON I’m testing with:
{
"request": {
"url": "https://api.example.com/v1/customer/details",
"method": "POST",
"headers": {
"Content-Type": "application/json",
"Authorization": "Bearer {{oauthToken}}"
},
"body": {
"customerId": "{{customer.id}}"
}
},
"response": {
"variables": {
"customer.tier": "data.customerInfo.tier",
"customer.status": "data.status"
}
}
}
The actual response from the API looks like this:
{
"success": true,
"data": {
"customerInfo": {
"id": "12345",
"tier": "Platinum"
},
"status": "active"
}
}
I’m using the dot notation data.customerInfo.tier in the mapping, which seems right based on the docs, but the variable customer.tier comes back empty after the action completes. I’ve tried removing the data. prefix and just using customerInfo.tier, but that didn’t work either. Is the mapping relative to the root of the JSON response, or do I need to specify the full path including the top-level data key? I’ve checked the logs and there are no errors, just the missing value. Any idea what I’m missing here?
The silent failure usually means the response parser doesn’t know how to flatten the nested object into the flat variable map. You’re likely trying to map a whole object to a string variable or vice versa without explicit pathing.
Architect Data Actions expect a very specific response structure. If the external API returns something like {"data": {"user": {"id": "123"}}}, you can’t just map data. You have to drill down.
Here is the corrected JSON structure for the Data Action. Notice the response object. It maps the specific nested path to your Architect variable.
{
"request": {
"url": "https://api.example.com/user",
"method": "GET",
"headers": {
"Authorization": "Bearer {{token}}"
}
},
"response": {
"user_id": "$.data.user.id",
"user_name": "$.data.user.name"
}
}
The key is the JSONPath syntax in the values. $.data.user.id tells Genesys exactly where to look. If you leave it as just data, the engine tries to cast the entire JSON object into the variable type defined in your Architect flow, which often fails silently if the types don’t match perfectly.
Also check your variable types in the Architect canvas. If user_id is defined as a Number in your flow, but the API returns a string "123", the mapping might fail or return null depending on strictness settings. I usually define these as Strings in Architect and cast them later if I need math.
One other thing. If the response has an array, like $.data.users[0].id, make sure you are actually expecting a single value. If you map an array to a scalar variable, it breaks. Use $.data.users[*].id only if you are mapping to a list variable in Architect.
Check the “Show Debug Info” box on the Data Action node in Architect. It will show the raw JSON response. That’s the only way to see if the path is wrong or if the API returned something unexpected.
