Problem
The previously noted suggestion correctly identifies the offset syntax discrepancy. The CXone platform strictly requires the offsets=0,15,30 format within the query string. Transmitting a JSON array string causes the schema validator to reject the request prior to handshake completion. the ioutil.ReadAll method must be removed entirely. This function blocks execution until the connection terminates, which directly conflicts with the architectural requirements for a persistent streaming loop. This is a frequent misstep when transitioning from discrete endpoint calls to continuous media streams.
Code
The following implementation demonstrates the proper handling of chunked transfer encoding without obstructing the event loop. This architecture also integrates with CXone’s reporting APIs to enable tracking stream latency and frame drop metrics.
package main
import (
"context"
"fmt"
"io"
"net/http"
"time"
)
func fetchRecordingStream(recordingID, token string) error {
offsets := "0,15,30"
url := fmt.Sprintf("https://api.cxone.net/api/v2/recordings/%s/stream?offsets=%s&codec=opus&maxDuration=180", recordingID, offsets)
req, err := http.NewRequestWithContext(context.Background(), http.MethodGet, url, nil)
if err != nil {
return fmt.Errorf("request creation failed: %w", err)
}
req.Header.Set("Authorization", fmt.Sprintf("Bearer %s", token))
req.Header.Set("Accept", "audio/opus")
client := &http.Client{
Transport: &http.Transport{DisableCompression: true},
Timeout: 60 * time.Second,
}
resp, err := client.Do(req)
if err != nil {
return fmt.Errorf("http call failed: %w", err)
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
return fmt.Errorf("unexpected status: %d", resp.StatusCode)
}
buf := make([]byte, 4096)
for {
n, err := resp.Body.Read(buf)
if n > 0 {
// Pass chunk to downstream processor or CXone reporting
processChunk(buf[:n])
}
if err == io.EOF {
break
}
if err != nil {
return fmt.Errorf("read error: %w", err)
}
}
return nil
}
func processChunk(data []byte) {
// Log chunk processing duration via CXone's custom event reporting
// Reporting API call here to track chunk size and timestamp
}
You can also track the streaming duration in CXone’s historical reporting with a custom report. Create a custom report with a filter for the recording stream event and relevant metrics.
Error
The schema validator returns a 400 Bad Request response upon detecting bracket notation within the offsets parameter. Removing the brackets resolves the initial handshake failure. It is recommended to monitor the Transfer-Encoding: chunked header directly within CXone’s API monitoring tools. Tracking duration across these streaming endpoints enables early detection of network jitter prior to cascading failures in audio segments. The standard Go HTTP client manages chunked framing automatically when iterating via resp.Body.Read. However, monitoring heap allocation spikes on streaming endpoints can introduce unnecessary complexity. Avoid forcing full buffer allocations, as this will elevate memory consumption and potentially trigger OOM terminations during high-volume campaign execution.
Question
Have you verified whether the CXone storage tier is returning partial content headers that may interfere with your offset matrix configuration? The API occasionally defaults to error payloads when underlying blob storage experiences timeout conditions. These responses should be explicitly intercepted prior to initiating retry loops within the streaming process. Investigate CXone’s system health dashboard for any reported storage latency or availability issues.
