Overview

You can use the Synthetics API to:

• Fetch monitor(s) in an App
• Trigger monitor runs
• Create or Edit Monitors
• Schedule Monitor Pauses

To use the API, you'll need your API key for all requests and your Synthetics App ID and Monitor ID for some requests.

Getting the API Key

Your account's API Key can be found under Settings → API page.

• here, if your account is registered in the US region, or
• here, for the EU region

Getting the App ID & Monitor ID

• The <appId> and <monitorId> values can be extracted from the URL of the Monitor Overview page. For example, if the Monitor Overview page URL is https://apps.sematext.com/ui/synthetics/12345/monitors/276 then the appId is 12345 and monitorId is 276.
• The <appId> can also be obtained by sending a GET request using the above request header and <apiKey> to the required endpoint:

Region	Endpoint
US	https://apps.sematext.com/users-web/api/v3/apps
EU	https://apps.eu.sematext.com/users-web/api/v3/apps

Example:

curl -L -X GET 'https://apps.sematext.com/users-web/api/v3/apps' \
-H 'Authorization: apiKey 9bddb0a6-xxxx-xxxx-xxxx-397d15806cfd'

Response:

  "success": true,
  "message": null,
  "data": {
    "apps": [
      {
        "id": 17174,
        "name": "Bulk API Test",
        "appType": "Synthetics",
        "appTypeId": 40000,

From the above response, we can determine that the <appId> for the Synthetics App named Bulk API Test is 17174.
