Comma-separated list of fields to return. Defaults to all fields.
id,name,domainJSON-encoded filter object. All top-level conditions are combined with AND logic. Use $or for OR logic.
The available operators depend on the data type of the field you are filtering on.
String fields
Fields like name, domain, description, linkedin, source, externalId, location.
| Operator | Description | Example |
|---|---|---|
| (exact) | Exact match | {"name": "Linear"} |
$eq |
Explicit exact match | {"name": {"$eq": "Linear"}} |
$not |
Not equal | {"source": {"$not": "import"}} |
$in |
Matches any value in array | {"domain": {"$in": ["linear.app", "granola.so"]}} |

Multiple operators can be combined on one field:
{"value": {"$gte": 5000, "$lt": 10000}}
Date fields
Fields like closeDate, startDate, endDate, createdAt, updatedAt.
Values can be ISO 8601 strings ("2026-01-01", "2026-01-01T00:00:00Z") or relative time macros.
Relative time macros: +Nd / -Nd (days), +Nw / -Nw (weeks), +Nm / -Nm (months), +Ny / -Ny (years), +Nh / -Nh (hours), +Ns / -Ns (seconds), now().
| Operator | Description | Example |
|---|---|---|
$gte |

$lte |
On or before | {"closeDate": {"$lte": "2026-03-31"}} |
$gt |
After | {"createdAt": {"$gt": "2026-01-01T00:00:00Z"}} |
$lt |

$notExists |
Field is absent or null | {"closeDate": {"$notExists": true}} |
Date range example:
{"closeDate": {"$gte": "2026-01-01", "$lte": "2026-03-31"}}
Relative date example (closing in next 30 days):
{"closeDate": {"$gte": "now()", "$lte": "+30d"}}
Array fields
Fields like listIds, ownerIds, contactIds.
| Operator | Description | Example |
|---|---|---|
$includes |
Array contains the given value (use this β bare exact match is not supported) | {"listIds": {"$includes": "<LIST_UUID>"}} |
$notIncludes |
Array does not contain the given value | {"ownerIds": {"$notIncludes": "<USER_UUID>"}} |
$overlaps |
Array contains at least one of the given values | {"ownerIds": {"$overlaps": ["<UUID_1>", "<UUID_2>"]}} |
$notOverlaps |
Array contains none of the given values | {"listIds": {"$notOverlaps": ["<UUID_1>", "<UUID_2>"]}} |
$all |
Array contains all of the given values | {"listIds": {"$all": ["<UUID_1>", "<UUID_2>"]}} |
$length |
Filter by array length (supports nested operators) | {"contactIds": {"$length": {"$gte": 2}}} |
$exists |
Field is present and non-empty | {"ownerIds": {"$exists": true}} |
$notExists |
Field is absent or empty | {"ownerIds": {"$notExists": true}} |
UUID / ID fields
Fields like id, workspaceId, companyId, stage.
| Operator | Description | Example |
|---|---|---|
| (exact) | Exact match | {"stage": "<PIPELINE_STAGE_UUID>"} |
$in |

Boolean fields
Fields like archived.
| Operator | Description | Example |
|---|---|---|
| (exact) | Exact match | {"archived": false} |
$not |
Not equal | {"archived": {"$not": true}} |
Logical operators
These work across all data types.
$or β matches if any sub-condition is true:
{
"workspaceId": "<WORKSPACE_UUID>",
"$or": [
{"ownerIds": {"$overlaps": ["<USER_UUID_1>", "<USER_UUID_2>"]}},
{"closeDate": {"$gte": "2026-01-01"}}
]
}
$and β matches if all sub-conditions are true (useful when you need multiple conditions on the same field):
{
"$and": [
{"name": {"$contains": "Enterprise"}},
{"name": {"$notContains": "Test"}}
]
}
Dot-notation (relation filtering)
Use dot-syntax to filter records based on properties of related objects:
{"company.name": "Linear"}
{"company.domain": {"$in": ["linear.app", "granola.so"]}}
{"company.location.city": "San Francisco"}
{"companyProfile.categories": {"$overlaps": ["Sales", "Marketing"]}}
All operators available for the target field's data type can be used with dot-notation.
Custom property filtering
Custom properties are stored in the custom object on records, keyed by UUID. Use GET /api/columns to discover the available custom property IDs, types, and options for a workspace.
Filter on custom properties using custom.<COLUMN_ID> with operators appropriate for the column's type.
Note: For
selectandmultiselectcolumns, option values are UUIDs (thekeyfield from the column'soptionsarray). Use the UUID, not the human-readable name.
// Text custom property
{"custom.54e1ca7d-69c3-4b77-8266-8085b5834116": {"$contains": "enterprise"}}
// Select custom property (use the option key UUID)
{"custom.a1b2c3d4-e5f6-7890-abcd-ef1234567890": "3e839b5c-b311-4887-b2da-727d2d75cdd6"}
// Multi-select custom property (use option key UUIDs)
{"custom.b2c3d4e5-f6a7-8901-bcde-f12345678901": {"$overlaps": ["a1b1c1d1-e1f1-1111-aaaa-111111111111", "b2b2c2d2-e2f2-2222-bbbb-222222222222"]}}
// Currency/number custom property
{"custom.c3d4e5f6-a7b8-9012-cdef-123456789012": {"$gte": 100000}}
// Date custom property
{"custom.d4e5f6a7-b8c9-0123-defa-234567890123": {"$gte": "2026-01-01"}}
// Boolean custom property
{"custom.e5f6a7b8-c9d0-1234-efab-345678901234": true}
// Check if custom property has a value
{"custom.f6a7b8c9-d0e1-2345-fabc-456789012345": {"$exists": true}}
Complex example
All top-level keys are ANDed together:
{
"name": {"$contains": "Zero"},
"location.city": "Helsinki",
"location.country": {"$in": ["United Kingdom", "Germany", "Sweden"]},
"value": {"$gte": 10000},
"closeDate": {"$gte": "2026-01-01", "$lte": "2026-03-31"},
"ownerIds": {"$includes": "<USER_UUID>"},
"stage": {"$in": ["<UUID_1>", "<UUID_2>"]},
"lastActivity": {"$exists": true},
"companyProfile.categories": {"$overlaps": ["Sales", "Marketing"]},
"custom.54e1ca7d-69c3-4b77-8266-8085b5834116": {"$contains": "enterprise"}
}
