What is filter-structures?

A reference for writing dimension filters in a Google Analytics 4 data request. It shows the required JSON shape for one condition, all conditions, or any condition.

Use it when building filters for the get_ga4_data operation, including exact matches, partial text matches, AND conditions, and OR conditions.

It prevents the invalid dimension filter error caused by placing fields at the wrong level in the request.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.00919
Opus 5.5	$0.00014	$0.00368
Sonnet 5.5	$0.00007	$0.00184
Haiku 4.5	$0.00003	$0.00092

Security

Grade A, and why

filter-structures scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Filter Structures

The correct shape for dimension_filter in get_ga4_data. Wrong structure returns an "Invalid dimension_filter" error. Use these templates.

The one rule

Every leaf filter must be wrapped in a "filter" key. fieldName never appears at the top level.

// WRONG — fieldName at top level
{"fieldName": "sessionSource", "stringFilter": {"value": "google"}}

// CORRECT — wrapped in "filter"
{"filter": {"fieldName": "sessionSource", "stringFilter": {"value": "google"}}}

Template: single field filter

{
  "filter": {
    "fieldName": "DIMENSION_NAME",
    "stringFilter": {
      "value": "VALUE",
      "matchType": "EXACT"
    }
  }
}

matchType options: EXACT, BEGINS_WITH, ENDS_WITH, CONTAINS, FULL_REGEXP, PARTIAL_REGEXP

Template: AND — all conditions must match

{
  "andGroup": {
    "expressions": [
      {"filter": {"fieldName": "deviceCategory", "stringFilter": {"value": "mobile", "matchType": "EXACT"}}},
      {"filter": {"fieldName": "country", "stringFilter": {"value": "United States", "matchType": "EXACT"}}}
    ]
  }
}

Template: OR — any condition matches

{
  "orGroup": {
    "expressions": [
      {"filter": {"fieldName": "sessionDefaultChannelGroup", "stringFilter": {"value": "Organic Search", "matchType": "EXACT"}}},
      {"filter": {"fieldName": "sessionDefaultChannelGroup", "stringFilter": {"value": "Organic Social", "matchType": "EXACT"}}}
    ]
  }
}

Template: NOT — exclude matching sessions

{
  "notExpression": {
    "filter": {
      "fieldName": "sessionDefaultChannelGroup",
      "stringFilter": {"value": "Direct", "matchType": "EXACT"}
    }
  }
}

Template: IN LIST — match any of several values

{
  "filter": {
    "fieldName": "country",
    "inListFilter": {
      "values": ["United States", "United Kingdom", "Canada"]
    }
  }
}

Common wrong keys → correct keys

Wrong key	Correct key
`and_filter`	`andGroup`
`or_filter`	`orGroup`
`not_filter`	`notExpression`
`filters`	`expressions`
`field`	`fieldName`
`stringFilter.exact`	`stringFilter.value`
