Trying to send a canned response via POST /api/v2/conversations/messaging/{conversationId}/messages while maintaining our OTel trace context. The standard SDK method doesn’t seem to allow passing custom headers for the span propagation, so the downstream trace breaks. Is there a way to inject the traceparent header into this specific API call without dropping the context?
The docs state: “The PureCloudPlatformClientV2 SDK abstracts the underlying HTTP client, preventing direct manipulation of request headers for individual method calls.” That’s why you can’t just slap traceparent on the postConversationMessagingMessage call. You’ll hit a wall because the SDK handles auth and serialization internally.
You have two paths here. First, if you’re using Node.js, you can use the PlatformClient’s low-level apiClient to bypass the generated methods entirely. It’s messy but it works.
const { platformClient } = require('genesyscloud');
// Initialize as normal
const config = {
clientId: process.env.GC_CLIENT_ID,
clientSecret: process.env.GC_CLIENT_SECRET,
basePath: 'https://api.mypurecloud.com'
};
const client = platformClient.init(config);
// Get the raw API client instance
const apiClient = client.ApiClient.instance;
// Construct the request manually
const url = `/api/v2/conversations/messaging/${conversationId}/messages`;
const headers = {
'Content-Type': 'application/json',
'traceparent': `00-${traceId}-${spanId}-01` // Inject your context here
};
const payload = {
text: 'Your canned response text',
type: 'message'
};
// Execute the raw POST
apiClient.post(url, payload, headers)
.then(response => console.log('Sent:', response.data))
.catch(err => console.error('Failed:', err));
Second option: if you’re stuck with the high-level SDK, you can’t inject headers per-call. You’d need to wrap the SDK method in a proxy that intercepts the outgoing request, but that’s overkill for a single trace header. Most teams just log the correlation ID in the message text or metadata fields as a fallback when trace context breaks. The metadata approach is safer for long-running conversations anyway.
Just make sure your traceparent format complies with W3C Trace Context spec. The API will ignore malformed headers, so you won’t get a 400, you’ll just get silence. Check the response body for errors.
