XPath, JSONPath, jq, and CSS support comes baked in! You can be as specific as you need, use XPath exported from various XPath element query creation tools.
(We support LXML re:test
, re:match
and re:replace
.)
ChangeDetection.io supports a massive amount of notifications (including email, office365, custom APIs, etc) when a web-page has a change detected thanks to the apprise library. Simply set one or more notification URL's in the [edit] tab of that watch.
Just some examples
discord://webhook_id/webhook_token
flock://app_token/g:channel_id
gitter://token/room
gchat://workspace/key/token
msteams://TokenA/TokenB/TokenC/
o365://TenantID:AccountEmail/ClientID/ClientSecret/TargetEmail
rocket://user:password@hostname/#Channel
mailto://user:pass@example.com?to=receivingAddress@example.com
json://someserver.com/custom-api
syslog://
And everything else in this list!
Now you can also customise your notification content and use Jinja2 templating for their title and body!
Detect changes and monitor data in JSON API's by using either JSONPath or jq to filter, parse, and restructure JSON as needed.
This will re-parse the JSON and apply formatting to the text, making it super easy to monitor and detect changes in JSON API results
For more complex parsing, filtering, and modifying of JSON data, jq is recommended due to the built-in operators and functions. Refer to the documentation for more specific information on jq.
One big advantage of jq
is that you can use logic in your JSON filter, such as filters to only show items that have a value greater than/less than etc.
See the wiki https://github.com/dgtlmoon/changedetection.io/wiki/JSON-Selector-Filter-help for more information and examples
