Operations 6

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

GET /index.php?module=API&method=CustomDimensions.getCustomDimension Get the report for a custom dimension · Custom dimensions get custom dimension #
Ask an LLM
“What values did visitors have for my custom dimension, like membership tier, last month?”
“Can I get the report for a custom dimension that's been deactivated?”
Tell an agent
Get the report for custom dimension {idDimension} on site {idSite} for {period} {date}.
Show a flat report of dimension {idDimension} values for {date}.
GET /index.php?module=API&method=CustomDimensions.configureNewCustomDimension Create a new custom dimension · Custom dimensions configure new custom dimension #
Ask an LLM
“How do I add a custom dimension to track something like user type?”
“Can custom dimensions be deleted later, or are slots used up for good?”
Tell an agent
Create a {scope}-scoped custom dimension named {name} on site {idSite}, active {active}.
Add custom dimension {name} with scope {scope} and extraction rules {extractions}, active {active}.
GET /index.php?module=API&method=CustomDimensions.configureExistingCustomDimension Update an existing custom dimension · Custom dimensions configure existing custom dimension #
Ask an LLM
“Do I need to resend every value when I update a custom dimension?”
“Can I deactivate or rename a custom dimension I already configured?”
Tell an agent
Rename custom dimension {idDimension} on site {idSite} to {name}, keeping active {active}.
Set existing dimension {idDimension} active to {active} with name {name}.
GET /index.php?module=API&method=CustomDimensions.getConfiguredCustomDimensions List configured custom dimensions · Custom dimensions get configured custom dimensions #
Ask an LLM
“Which custom dimensions are set up on my site?”
“Can I see every configured custom dimension with its scope?”
Tell an agent
List the configured custom dimensions for site {idSite}.
Show every custom dimension defined on website {idSite}.
GET /index.php?module=API&method=CustomDimensions.getAvailableScopes List scopes and remaining dimension slots · Custom dimensions get available scopes #
Ask an LLM
“How many custom dimension slots do I have left on a site?”
“Which scopes, like visit or action, can a custom dimension use?”
Tell an agent
Show the available scopes and remaining slots for site {idSite}.
Check whether site {idSite} has room for another custom dimension.
GET /index.php?module=API&method=CustomDimensions.getAvailableExtractionDimensions List dimensions usable in extraction rules · Custom dimensions get available extraction dimensions #
Ask an LLM
“What can a custom dimension extract its value from, like the page URL?”
“Which dimensions are supported in extraction rules?”
Tell an agent
List the dimensions I can use in custom dimension extraction rules.
Show the sources a value can be extracted from.
