Scripting API 400 on Zendesk Trigger Migration

General Discussion
1

I’m trying to figure out why the Scripting API returns a 400 Bad Request when converting Zendesk ticket triggers to GC interaction scripts.

The endpoint POST /api/v2/scripts rejects the payload because GC expects a specific id format for the steps array, unlike Zendesk’s flat structure.

{
 "code": 400,
 "message": "Validation failed for object 'steps[0]'"
}

How should I map the Zendesk trigger conditions to the GC scripting engine without hitting this validation error?

This is actually a known issue… when pushing payloads via jmeter, the id format needs to be uuid v4. just generate a random uuid for each step id before posting. also check if you are hitting the api rate limit if you are batching these imports. usually a simple loop in the script fixes the validation error.

If I remember right, the step IDs must strictly adhere to UUID v4 standards. The documentation outlines this requirement clearly: Genesys Cloud Developer Center. Ensure each step in the steps array contains a unique, valid UUID to resolve the 400 error.

{
 "id": "550e8400-e29b-41d4-a716-446655440000",
 "type": "say",
 "text": "Hello"
}

Have you tried forcing the uuid format on the step id? the sdk validator rejects anything that doesn’t look like a proper v4 string.

so the uuid fix worked but there’s a catch with the .NET SDK that nobody mentions. if you just generate a guid and pass it as a string, the serializer might still trip up depending on how you’re building the request body. i’m using the PureCloudPlatformClientV2 in an azure function to migrate these triggers and ran into the same 400.

the issue isn’t just the id format, it’s how the ScriptStep object gets serialized. the docs say “each step must have a unique identifier” but they don’t specify that the c# property needs explicit handling if you’re bypassing the SDK’s model builder.

here’s what actually worked for me in c#:

var steps = new List<ScriptStep>();
foreach (var zendeskAction in zendeskTrigger.Actions)
{
 var step = new ScriptStep();
 step.Id = Guid.NewGuid().ToString(); // strictly v4
 step.Type = "say"; 
 step.Text = zendeskAction.Value;
 
 // critical: ensure the step has a valid sequence
 step.Sequence = steps.Count + 1;
 steps.Add(step);
}

var script = new Script();
script.Name = $"Migrated-{zendeskTrigger.Name}";
script.Steps = steps;
script.Language = "en-US";

var result = await scriptsApi.PostScript(script);

don’t forget to set the Language property. if that’s missing, the api throws a different 400 that looks like a step error but isn’t. also, the Sequence property is mandatory for the steps array to be valid. the sdk doesn’t auto-increment it.

i was hitting the rate limit too when batch importing, so i added a simple exponential backoff in the azure function. the retry-after header is your friend here. also, make sure you’re not including any zendesk-specific metadata in the CustomProperties unless you map it to gc variables first, or the validation fails silently on some fields.

it’s frustrating that the error message is so vague. “validation failed for object ‘steps[0]’” tells you nothing about which field is wrong. anyway, hope this saves you some debugging time. the guid generation is standard but the sequence and language fields are the gotchas.
