Highly configurable: WithHTTPClient(), WithBaseURL(), WithUserAgent(), WithErrLog(), WithCheckUUID(), WithAutoProvision(), etc.
Automatic determination of HTTP method (POST, HEAD) based on body existence
Auto mode: just call client.Auto(time.Duration) and client will send Success() request automatically with specified frequency
Global mode: init client once with healthchecks.New(), and access it from anywhere by calling healthchecks.Global()

Check godoc for more details.

package main

import (
    "time"

    "gitlab.com/etke.cc/go/healthchecks/v2"
)

var hc *healthchecks.Client

func main() {
    hc = healthchecks.New(
        healthchecks.WithCheckUUID("CHECK_UUID")
    )
    defer hc.Shutdown()
    // send basic success request
    hc.Success()

    // or use auto mode, that will send success request with the specified frequency
    go hc.Auto(1*time.Minute)

    // need to call the client from another place in your project?
    // just call healthchecks.Global() and you will get the same client
