Architect Flow State PATCH 422 - INVALID_JSON

Administration
1

hey! we’re getting a 422 on a PUT to /api/v2/flows/{flowId} - specifically trying to update the wrapup code on a TRANSFER step in ARCHITECT. it’s weird because the UI works fine, but the API call fails every time.

“INVALID_JSON: One or more request parameters contain invalid JSON.”

The payload looks good, and it validates against the schema. it’s this part that’s breaking it:

{
 "parameters": {
 "wrapupCode": {
 "wrapupCode": "CompleteCall"
 }
 }
}

We’re on Genesys Cloud, and using the Python SDK v6.12.0. I even tried manually encoding the payload to ensure no weird characters are slipping in. The documentation doesn’t say anything about needing to escape the wrapup code. The WRAPUP CODES are all CAPITALIZED in our configuration, that’s how we roll.

resource “genesyscloud_architect_flow” “example” {
name = “Data Action Test”
description = “Test flow for data action”
version = “1.0”
data_action…
}

If it helps, we had an issue with PATCH requests - the JSON seemed valid, but the content type header was incorrect. Try setting Content-Type: application/json explicitly. Sometimes the client defaults to something else.

Content-Type’s the first thing I checked too - the earlier reply covers it, that’s usually it. But the error’s a bit misleading - it’s not just the header. The Architect API’s fussy about the JSON structure, even if it validates against the schema. Specifically, nested objects in the parameters field. It wants those flattened. Try this payload instead - the wrapup code is now a direct child of parameters, not nested under another object.

{
 "parameters": {
 "transfer.wrapupCode": "COMPLETE",
 "transfer.wrapupReason": "Customer issue resolved"
 }
}

Side note - we hit this when automating flow updates after deployments. The audit trail showed the JSON as valid, but the API silently failed. The workaround was to pre-flatten the parameters on the client-side before sending the PATCH. It’s a pain, but it avoids the 422. Also, ensure your token TTL’s long enough - short tokens break the chain of custody during updates and can cause transient errors like this.

tried setting the Content-Type header - no change. still getting the 422, but now the error message is different - says “INVALID_VALUE: wrapup_code must be a valid UUID”. the wrapup code is a valid UUID in our system, and it’s working fine when I change it through the Admin UI though.

Totally understandable frustration - UUID validation errors are a nightmare when the value looks perfect. This usually happens because the API expects the raw ID string without any surrounding quotes or object wrappers inside the JSON path for that specific flow property.

  1. Verify the ID using GET /api/v2/routing/wrapupcodes/divisionviews to ensure you’ve got the actual ID and not the name.
  2. Strip any extra formatting from the payload.
  3. Pass the UUID as a plain string.
{
 "wrapupCode": "f47ac10b-58cc-4372-a567-0e02b2c3d479"
}
