Pinging API

With the Pinging API, you can signal success, fail, and start events from your systems.

General Notes

All ping endpoints support:

  • HTTP and HTTPS
  • HTTP 1.0, HTTP 1.1 and HTTP 2
  • IPv4 and IPv6
  • HEAD, GET, and POST requests methods. The HTTP POST requests can optionally include diagnostic information in the request body. If the request body looks like a UTF-8 string, Healthchecks stores the request body (limited to the first 10KB for each received ping).

Successful responses will have the "200 OK" HTTP response status code and a short "OK" string in the response body.

Send a "success" Signal

HEAD|GET|POST https://hc.oceanx.org/ping/{uuid}

Signals to Healthchecks that the job has completed successfully (or, continuously running processes are still running and healthy). The uuid parameter is unique for each check.

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278 HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK

Send a "fail" Signal

HEAD|GET|POST https://hc.oceanx.org/ping/{uuid}/fail

Signals to Healthchecks that the job has failed. Actively signaling a failure minimizes the delay from your monitored service failing to you receiving an alert.

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/fail HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK

Send a "start" Signal

HEAD|GET|POST https://hc.oceanx.org/ping/{uuid}/start

Sends a "job has started!" message to Healthchecks. Sending a "start" signal is optional, but it enables a few extra features:

  • Healthchecks will measure and display job execution times
  • Healthchecks will detect if the job runs longer than its configured grace time

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/start HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK

Report Script's Exit Status

HEAD|GET|POST https://hc.oceanx.org/ping/{uuid}/{exit-status}

Sends a success or failure signal depending on the exit status included in the URL. The exit status is a 0-255 integer. Healthchecks interprets 0 as success and all other values as failure.

Example

GET /5bf66975-d4c7-4bf5-bcc8-b8d8a82ea278/1 HTTP/1.0
Host: hc-ping.com

HTTP/1.1 200 OK
Server: nginx
Date: Wed, 29 Jan 2020 09:58:23 GMT
Content-Type: text/plain; charset=utf-8
Content-Length: 2
Connection: close
Access-Control-Allow-Origin: *

OK
