Add endpoint as the receiver in the prometheus alert configuration - spring-boot

Question

I am trying to activate my spring boot application endpoints with the alerts, for the required event that is defined in the alert rules of prometheus is broken, so that I want to add my application endpoints as a receiver to receive alerts from the prometheus alertmanager. Can anyone please suggest how to configure endpoint as a receiver to this receiver label, instead of any other push notifiers?
- receiver: 'frontend-pager'
group_by: [product, environment]
matchers:
- team="frontend"

I think 'webhook receiver' can help you. More information can refer doc https://prometheus.io/docs/alerting/latest/configuration/#webhook_config
This is an example of a webhook alert created based on blackbox_exporter's metric scraping.
prometheus rule setting
You need to create rule(s) to trigger alert, defined a rule named 'http_health_alert' here as example.
groups:
- name: http
rules:
- alert: http_health_alert
expr: probe_success == 0
for: 3m
labels:
type: http_health
annotations:
description: Health check for {{$labels.instance}} is down
Alertmanager setting
'match' is set to http_health_alert, the alert will be sent to'http://example.com/alert/receiver' via HTTP/POST method (I think you will prepare in advance).
The alert will post JSON format to the configured endpoint 'http://example.com/alert/receiver'. And you can also customize different receiving methods or receiving information in the endpoint/program for different label contents.
global:
route:
group_by: [alertname, env]
group_wait: 30s
group_interval: 3m
repeat_interval: 1h
routes:
- match:
alertname: http_health_alert
group_by: [alertname, env]
group_wait: 30s
group_interval: 3m
repeat_interval: 1h
receiver: webhook_receiver
receivers:
- name: webhook_receiver
webhook_configs:
- send_resolved: true
url: http://example.com/alert/receiver
- name: other_receiver
email_configs:
- send_resolved: true
