## What is DeltaAlert?

#API Monitoring Toolkit
Automatically polls your API at the interval you choose and sends a push notification the instant the response changes.

#Flexible push alerts
For each condition group you can freely customise the notification’s title, body and deep-link URL.
Highlight only the critical values, or jump straight to a browser after the change—whatever fits your workflow.

#Powerful filtering rules
Combine multiple JSON key paths and expected values with logical AND to create fine-grained triggers.

#Key-path syntax examples
foo – top-level key
foo.bar – dot notation for nesting
foo.* – all children under foo
foo.[0] – array index

Please confirm in advance that the target API’s terms allow automated monitoring.
Push delivery may be delayed or lost due to network conditions or third-party service outages.
