go-pagerduty
go-pagerduty is a CLI and go client library for the PagerDuty API.
Installation
To add the latest stable version to your project:
go get github.com/PagerDuty/[email protected]
If you instead wish to work with the latest code from main:
go get github.com/PagerDuty/go-pagerduty@latest
Usage
CLI
The CLI requires an authentication token, which can be specified in .pd.yml
file in the home directory of the user, or passed as a command-line argument.
Example of config file:
---
authtoken: fooBar
Commands
pd
command provides a single entrypoint for all the API endpoints, with individual
API represented by their own sub commands. For an exhaustive list of sub-commands, try:
pd --help
An example of the service

Client Library
NOTICE: Breaking API Changes in v1.5.0
As part of the v1.5.0
release, we have fixed features that have never worked
correctly and require a breaking API change to fix. One example is the issue
reported in #232, as
well as a handful of other examples within the v1.5.0
milestone.
If you are impacted by a breaking change in this release, you should audit the
functionality you depended on as it may not have been working. If you cannot
upgrade for some reason, the v1.4.x
line of releases should still work. At the
time of writing v1.4.3
was the latest, and we intend to backport any critical
fixes for the time being.
Example Usage
package main
import (
"fmt"
"github.com/PagerDuty/go-pagerduty"
)
var authtoken = "" // Set your auth token here
func main() {
var opts pagerduty.ListEscalationPoliciesOptions
client := pagerduty.NewClient(authtoken)
eps, err := client.ListEscalationPolicies(opts)
if err != nil {
panic(err)
}
for _, p := range eps.EscalationPolicies {
fmt.Println(p.Name)
}
}
The PagerDuty API client also exposes its HTTP client as the HTTPClient
field.
If you need to use your own HTTP client, for doing things like defining your own
transport settings, you can replace the default HTTP client with your own by
simply by setting a new value in the HTTPClient
field.
API Error Responses
For cases where your request results in an error from the API, you can use the
errors.As()
function from the standard library to extract the
pagerduty.APIError
error value and inspect more details about the error,
including the HTTP response code and PagerDuty API Error Code.
package main
import (
"fmt"
"github.com/PagerDuty/go-pagerduty"
)
var authtoken = "" // Set your auth token here
func main() {
client := pagerduty.NewClient(authtoken)
user, err := client.GetUser("NOTREAL", pagerduty.GetUserOptions{})
if err != nil {
var aerr pagerduty.APIError
if errors.As(err, &aerr) {
if aerr.RateLimited() {
fmt.Println("rate limited")
return
}
fmt.Println("unknown status code:", aerr.StatusCode)
return
}
panic(err)
}
fmt.Println(user)
}
Extending and Debugging Client
Extending The Client
The *pagerduty.Client
has a Do
method which allows consumers to wrap the
client, and make their own requests to the PagerDuty API. The method signature
is similar to that of the http.Client.Do
method, except it also includes a
bool
to incidate whether the API endpoint is authenticated (i.e., the REST
API). When the API is authenticated, the client will annotate the request with
the appropriate headers to be authenticated by the API.
If the PagerDuty client doesn't natively expose functionality that you wish to
use, such as undocumented JSON fields, you can use the Do()
method to issue
your own request that you can parse the response of.
Likewise, you can use it to issue requests to the API for the purposes of debugging. However, that's not the only mechanism for debugging.
Debugging the Client
The *pagerduty.Client
has a method that allows consumers to enable debug
functionality, including interception of PagerDuty API responses. This is done
by using the SetDebugFlag()
method using the pagerduty.DebugFlag
unsigned
integer type. There are also exported constants to help consumers enable
specific debug behaviors.
Capturing Last PagerDuty Response
If you're not getting the response you expect from the PagerDuty Go client, you
can enable the DebugCaptureLastResponse
debug flag to capture the HTTP
responses. You can then use one of the methods to make an API call, and then
inspect the API response received. For example:
client := pagerduty.NewClient("example")
client.SetDebugFlag(pagerduty.DebugCaptureLastResponse)
oncalls, err := client.ListOnCallsWithContext(ctx, pagerduty.ListOnCallOptions{})
resp, ok := client.LastAPIResponse()
if ok { // resp is an *http.Response we can inspect
body, err := httputil.DumpResponse(resp, true)
// ...
}
Included Packages
webhookv3
Support for V3 of PagerDuty Webhooks is provided via the webhookv3
package.
The intent is for this package to provide signature verification and decoding
helpers.
