Added in version 0.13

REST API is supported since version 0.13. Make sure you're using the latest version of Logdy.

This is a documentation of the REST API that is exposed for Logdy instance. The endpoints documented on this page will be only accessible after you define an ApiKey config parameter, either via CLI or Go Code.


API requests made to Uptime API are authorized using a Bearer Authentication standard. That means you'll only need to add a header with Authorization: Bearer $TOKEN to your requests.

API Token is defined during startup through command line argument or via config object


If you're running Logdy in the code embedded mode and you're using a path prefix. Then you need to add that prefix to the path. Example: Logdy running on http://localhost:8080/logdy-ui, the logging endpoint will be http://localhost:8080/logdy-ui/api/log

POST /api/log

Allows you to send log message(s) to Logdy instance.

Request - body parameters

Example sending log as a string


The examples below assume you're running Logdy locally on port 8080 and don't use path prefix.

curl --location --request POST 'localhost:8080/api/log' \
--header 'Authorization: Bearer foobar' \
--header 'Content-Type: application/json' \
--data '{"logs": [{"log": "this is a log message as a string" }],"source":"machine identifier"}'

Example sending log as a string JSON

curl --location --request POST 'localhost:8080/api/log' \
--header 'Authorization: Bearer foobar' \
--header 'Content-Type: application/json' \
--data '{"logs": [{"log": {"value": "json fits here too"} }],"source":"machine identifier"}'
