Send and verify events with OpenAI Responses API telemetry
Use OpenAI Responses API telemetry where your app knows the final result. Collect only the fields you need, then verify a test event before building charts.
- 1
Choose the outcome
Responses API cost and latency analysis
- 2
Define the contract
operation_id, response_id, feature, workflow, provider, model, and release
- 3
Log the final result
Wrap the application-owned Responses API call and emit one final request event after usage and outcome are known.
- 4
Check the stored event
Exercise a known fixture, then inspect openai_response_completed for one correctly typed terminal row.
Before you start
Before you start
- The official OpenAI JavaScript SDK and telemetry-sh initialized in trusted server code
- An application-owned operation ID plus stable feature, workflow, model-alias, and release names
- A reviewed policy for prompt, response, tool, and identifier data
Delivery setup
Install and initialize server-side
Import telemetry-sh in server-only code and initialize it once with process.env.TELEMETRY_API_KEY. Keep ingestion credentials out of browser bundles, client-visible environment variables, source control, logs, and exception messages.
npm installation
npm install telemetry-sh- 1Create one reusable server-side client. Set its timeout and retry limit.
- 2Log an event when the operation succeeds, fails, retries, or times out.
- 3Send test events with known results and inspect the stored rows before enabling an alert.
Snippet
Start with one structured event
Add this shape where the workflow completes, fails, or retries. Then build the dashboard from real fields.
OpenAI Responses API telemetry event
import OpenAI from "openai";
import { Telemetry } from "telemetry-sh";
const openai = new OpenAI();
const telemetry = new Telemetry(process.env.TELEMETRY_API_KEY);
const startedAt = performance.now();
let response;
let status = "success";
let errorType;
try {
response = await openai.responses.create({
model: process.env.OPENAI_MODEL ?? "gpt-5.6",
input: approvedInput,
});
return response.output_text;
} catch (error) {
status = "failed";
errorType = classifyOpenAIError(error);
throw error;
} finally {
await telemetry.log("openai_response_completed", {
operation_id: operationId,
response_id: response?.id,
feature: "support_draft",
provider: "openai",
model: response?.model ?? process.env.OPENAI_MODEL ?? "gpt-5.6",
status,
error_type: errorType,
duration_ms: Math.round(performance.now() - startedAt),
input_tokens: response?.usage?.input_tokens ?? 0,
output_tokens: response?.usage?.output_tokens ?? 0,
total_tokens: response?.usage?.total_tokens ?? 0,
release: process.env.APP_RELEASE,
});
}Event schema
operation_id, response_id, feature, workflow, provider, model, and release
status, duration_ms, input_tokens, output_tokens, total_tokens, retry_count, and error_type
tool_call_count, accepted, human_handoff, estimated_cost_usd, and pricing_version when approved
Check your setup
Checkpoint 1
Wrap the application-owned Responses API call and emit one final request event after usage and outcome are known.
Checkpoint 2
Provider usage supports token accounting, but cost is an application-owned estimate that needs a dated price source and separate reconciliation.
Checkpoint 3
Keep prompts, generated output, tool arguments, tool results, API keys, and unrestricted exception messages out of the event by default.
Verification
Prove the event arrived
Run this after exercising known success and failure cases. Replace the fallback table name if your final event contract differs from the snippet.
OpenAI Responses API telemetry verification query
SELECT *
FROM openai_response_completed
ORDER BY timestamp_utc DESC
LIMIT 20;Implementation references
Review the event contract, data-safety guidance, and upstream primary documentation before enabling a new production path.
Where to log
Keep the outcome event small and recoverable
This pattern provides
- Record the outcome as an event you can query with SQL.
- Stable fields for dashboards, alerts, and cross-event correlation.
- Test events for checking success, failure, retries, and timeouts.
This pattern does not provide
- An OTLP exporter, automatic collection pipeline, or replacement for detailed traces and diagnostic logs.
- Exactly-once delivery merely because the payload contains an event ID.
- Permission to collect raw provider payloads, user content, credentials, or regulated data.
