Your requests to Health Checks Management API must authenticate using an API key. All API keys are project-specific. There are no account-wide API keys. By default, a project on Health Checks doesn't have an API key. You can create read-write and read-only API keys on the Project Settings page.
Only works with the following API endpoints:
Omits sensitive information from the API responses. See the documentation of individual API endpoints for details.
The client can authenticate itself by including an X-Api-Key: <your-api-key>
header in an HTTP request. Alternatively, for POST requests with a JSON request body,
the client can put an api_key field in the JSON document.
See the Create a new check section for an example.
For POST requests, the Health Checks API expects the request body to be
a JSON document (not a multipart/form-data encoded form data).
Health Checks uses HTTP status codes wherever possible. In general, 2xx class indicates success, 4xx indicates a client error, and 5xx indicates a server error.
The response may contain a JSON document with additional data.
GET https://healthcheck.ddmnet.com/api/v1/checks/
Returns a list of checks belonging to the user, optionally filtered by one or more tags.
Filters the checks and returns only the checks that are tagged with the specified value.
This parameter can be repeated multiple times.
Example:
https://healthcheck.ddmnet.com/api/v1/checks/?tag=foo&tag=bar
curl --header "X-Api-Key: your-api-key" https://healthcheck.ddmnet.com/api/v1/checks/

When using the read-only API key, Health Checks omits the following fields from responses:
ping_url, update_url, pause_url, channels. It adds an extra
unique_key field. The unique_key identifier is stable across API calls, and
you can use it in the Get a single check
and Get a list of check's status changes API calls.

POST https://healthcheck.ddmnet.com/api/v1/checks/
Creates a new check and returns its ping URL. All request parameters are optional and will use their default values if omitted.
With this API call, you can create both Simple and Cron checks:
timeout parameter.schedule and tz parameters.string, optional, default value: ""
Name for the new check.
string, optional, default value: ""
A space-delimited list of tags for the new check. Example:
{"tags": "reports staging"}
string, optional.
Description of the check.
number, optional, default value: 86400.
A number of seconds, the expected period of this check.
Minimum: 60 (one minute), maximum: 2592000 (30 days).
Example for a 5-minute timeout:
{"kind": "simple", "timeout": 300}
number, optional, default value: 3600.
A number of seconds, the grace period for this check.
Minimum: 60 (one minute), maximum: 2592000 (30 days).
string, optional, default value: "* * * * *".
A cron expression defining this check's schedule.
If you specify both timeout and schedule parameters,
Health Checks will create a Cron check and ignore
the timeout value.
Example for a check running every half-hour:
{"schedule": "0,30 * * "}
string, optional, default value: "UTC".
Server's timezone. This setting only has an effect in combination with the
schedule parameter.
Example:
{"tz": "Europe/Riga"}
boolean, optional, default value: false.
Controls whether a paused check automatically resumes when pinged (the default) or not. If set to false, a paused check will leave the paused state when it receives a ping. If set to true, a paused check will ignore pings and stay paused until you manually resume it from the web dashboard.
string, optional, default value: "".
Specifies the allowed HTTP methods for making ping requests. Must be one of the two values: "" (an empty string) or "POST".
Set this field to "" (an empty string) to allow HEAD, GET, and POST requests.
Set this field to "POST" to allow only POST requests.
Example:
{"methods": "POST"}
string, optional
By default, this API call assigns no integrations to the newly created check.
Set this field to a special value "*" to automatically assign all existing integrations. Example:
{"channels": "*"}
To assign specific integrations, use a comma-separated list of integration UUIDs. You can look up integration UUIDs using the Get a List of Existing Integrations API call.
Example:
{"channels":
"4ec5a071-2d08-4baa-898a-eb4eb3cd6941,746a083e-f542-4554-be1a-707ce16d3acc"}
Alternatively, if you have named your integrations in Health Checks dashboard, you can specify integrations by their names. For this to work, your integrations need non-empty unique names, and they must not contain commas. The names must match exactly, whitespace is significant.
Example:
{"channels": "Email to Alice,SMS to Alice"}
array of string values, optional, default value: [].
Enables "upsert" functionality. Before creating a check, Health Checks looks for
existing checks, filtered by fields listed in unique.
If Health Checks does not find a matching check, it creates a new check and returns it with the HTTP status code 201.
If Health Checks finds a matching check, it updates the existing check and returns it with HTTP status code 200.
The accepted values for the unique field are
name, tags, timeout, and grace.
Example:
{"name": "Backups", unique: ["name"]}
In this example, if a check named "Backups" exists, it will be returned. Otherwise, a new check will be created and returned.

POST https://healthcheck.ddmnet.com/api/v1/checks/<uuid>/pause
Disables monitoring for a check without removing it. The check goes into a "paused" state. You can resume monitoring of the check by pinging it.
This API call has no request parameters.
curl https://healthcheck.ddmnet.com/api/v1/checks/0c8983c9-9d73-446f-adb5-0641fdacc9d4/pause \
--request POST --header "X-Api-Key: your-api-key" --data ""
Note: the --data "" argument forces curl to send a Content-Length request header
even though the request body is empty. For HTTP POST requests, the Content-Length
header is sometimes required by some network proxies and web servers.
