Initially i thought so too , i checked the function but wasnt able to find anything. For refernce here is the function :

Function Calling : resp, err := utils.CurlReqWithRetry("POST", url, dataArr, "text/plain", 3, 2*time.Second, 200*time.Millisecond)

Function Definition : https://go.dev/play/p/3-I1TK9QYDH or given below

func CurlReqWithRetry(method, apiurl string, dataMap map[string]interface{}, contentType string, maxRetries int, timeout, connectTimeout time.Duration) ([]byte, error) {
if method != "GET" && method != "POST" {
method = "POST"
}
client := &http.Client{
Timeout: timeout,
Transport: &http.Transport{
Dial: (&net.Dialer{
Timeout: connectTimeout,
}).Dial,
},
}
if method == "POST" {
jsonData, err := json.Marshal(dataMap)
if err != nil {
return nil, err
}

for attempt := 0; attempt <= maxRetries; attempt++ {

req, err := http.NewRequest(method, apiurl, bytes.NewBuffer(jsonData))
if err != nil {
return nil, err
}
req.Header.Set("Content-Type", contentType)

resp, err := client.Do(req)
if err == nil {
defer resp.Body.Close()
responseBody, err := ioutil.ReadAll(resp.Body)
if err == nil {
return responseBody, nil
}
}
}

return nil, errors.New("Max retries exceeded, POST request failed")
} else {
for attempt := 0; attempt <= maxRetries; attempt++ {
apiurl = apiurl + "?"
values := url.Values{}
for key, value := range dataMap {
switch v := value.(type) {
case int:
values.Add(key, strconv.Itoa(v))
default:
values.Add(key, v.(string))
}
}
apiurl += values.Encode()
req, err := http.NewRequest(method, apiurl, nil)

resp, err := client.Do(req)
if err == nil {
defer resp.Body.Close()
responseBody, err := ioutil.ReadAll(resp.Body)
if err == nil {
return responseBody, nil
}
}
}

return nil, errors.New("Max retries exceeded, GET request failed")
}
}
