List Tags

GET /space/{space_id}/tag

List Tags

Operation ID: ListTags

Parameters

Path Parameters

Parameter	Type	Required	Description
space_id	string	✓	Unique identifier for a space_id

Query Parameters

Parameter	Type	Required	Description
where	string		The specified string is an expression for the purpose of filtering the list of Tags returned. The expression syntax was inspired by SQL. It supports conjunctions using AND of relational expressions of the form attribute operator attribute_or_literal. The attribute names are case-sensitive and PascalCase, as in the JSON encoding. Strings support the following operators: <, >, <=, >=, =, !=, LIKE, NOT LIKE, ILIKE, ~~, !~~, ~, ~*, !~, !~*, IN, NOT IN. String pattern operators: LIKE and ~~ for pattern matching with % and _ wildcards, ILIKE for case-insensitive pattern matching, NOT LIKE and !~~ for negated pattern matching. String regex operators: ~ for regex matching, ~* for case-insensitive regex, !~ and !~* for regex not matching (case-sensitive and insensitive). Integers support the following operators: <, >, <=, >=, =, !=, IN, NOT IN. UUIDs and boolean attributes support equality and inequality only. UUID and time literals must be quoted as string literals. String literals are quoted with single quotes, such as 'string'. Time literals use the same form as when serialized as JSON, such as: CreatedAt > '2025-02-18T23:16:34'. Integer and boolean literals are also supported for attributes of those types. Arrays support the ? operator to to match any element of the array, as in ApprovedBy ? '7c61626f-ddbe-41af-93f6-b69f4ab6d308'. Arrays can perform LEN() to check for length, as in LEN(ApprovedBy) > 0. Map support the dot notation to specify a particular map key, as in Labels.tier = 'Backend'. Maps support IS NULL and IS NOT NULL with dot notation to check for key absence or presence, as in Labels.tier IS NULL (key doesn't exist) or Labels.tier IS NOT NULL (key exists). Comparison results can be tested with IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE. These are useful for nullable columns: MergeSourceID = '<uuid>' IS NOT FALSE matches rows where MergeSourceID equals the value OR is NULL. The IN and NOT IN operators accept a comma-separated list of values in parentheses, such as Slug IN ('slugone', 'slugtwo') or Labels.environment IN ('prod', 'staging'). Conjunctions are supported using the AND operator. An example conjunction is: CreatedAt >= '2025-01-07' AND Slug = 'test' AND Labels.mykey = 'myvalue'. Supported attributes for filtering on Tag: Annotations, ChangeSetID, CreatedAt, DeleteGates, DisplayName, Labels, OrganizationID, Slug, SpaceID, TagID, UpdatedAt. The whole string must be query-encoded.
filter	string		UUID of a Filter entity to apply to the Tag list. The Filter must be in the same Organization as the user credentials. The Filter's From field must match the entity type being filtered (Tag). For Space-resident entities, if the Filter has a FromSpaceID, it must match the operation's SpaceID. The Filter's Where clause will be combined with any explicit 'where' parameter using AND logic. If both 'filter' and 'where' parameters are specified, they are combined with AND logic.
contains	string		Free text search that approximately matches the specified string against string fields and map keys/values. The search is case-insensitive and uses pattern matching to find entities containing the text. Searchable string fields include attributes like Slug, DisplayName, and string-typed custom fields. For map fields (like Labels and Annotations), the search matches both map keys and values. The search uses OR logic across all searchable fields, so matching any field will return the entity. If both 'where' and 'contains' parameters are specified, they are combined with AND logic. Searchable fields for Tag include string and map-type attributes from the queryable attributes list. The whole string must be query-encoded.
include	string		Include clause for expanding related entities in the response for Tag. The attribute names are case-sensitive, PascalCase, and expected in a comma-separated list format as in the JSON encoding. Supported attributes for Tag are ChangeSetID, OrganizationID, SpaceID. The whole string must be query-encoded.
select	string		Select clause for specifying which fields to include in the response for Tag. The attribute names are case-sensitive, PascalCase, and expected in a comma-separated list format as in the JSON encoding. If not specified, all fields are returned. Entity and parent IDs (like OrganizationID, SpaceID, TagID) and Slug are always returned regardless of the select parameter. Fields used in where and contains filters are also automatically included. Example: 'DisplayName,CreatedAt,Labels' will return only those fields plus the required ID and Slug fields. The whole string must be query-encoded.

String regex operators: ~ for regex matching, ~* for case-insensitive regex, !~ and !~* for regex not matching (case-sensitive and insensitive). Integers support the following operators: <, >, <=, >=, =, !=, IN, NOT IN. UUIDs and boolean attributes support equality and inequality only. UUID and time literals must be quoted as string literals. String literals are quoted with single quotes, such as 'string'. Time literals use the same form as when serialized as JSON, such as: CreatedAt > '2025-02-18T23:16:34'. Integer and boolean literals are also supported for attributes of those types. Arrays support the ? operator to to match any element of the array, as in ApprovedBy ? '7c61626f-ddbe-41af-93f6-b69f4ab6d308'. Arrays can perform LEN() to check for length, as in LEN(ApprovedBy) > 0. Map support the dot notation to specify a particular map key, as in Labels.tier = 'Backend'. Maps support IS NULL and IS NOT NULL with dot notation to check for key absence or presence, as in Labels.tier IS NULL (key doesn't exist) or Labels.tier IS NOT NULL (key exists). Comparison results can be tested with IS TRUE, IS FALSE, IS NOT TRUE, and IS NOT FALSE. These are useful for nullable columns: MergeSourceID = '<uuid>' IS NOT FALSE matches rows where MergeSourceID equals the value OR is NULL. The IN and NOT IN operators accept a comma-separated list of values in parentheses, such as Slug IN ('slugone', 'slugtwo') or Labels.environment IN ('prod', 'staging'). Conjunctions are supported using the AND operator. An example conjunction is: CreatedAt >= '2025-01-07' AND Slug = 'test' AND Labels.mykey = 'myvalue'. Supported attributes for filtering on Tag: Annotations, ChangeSetID, CreatedAt, DeleteGates, DisplayName, Labels, OrganizationID, Slug, SpaceID, TagID, UpdatedAt. The whole string must be query-encoded.
filter	string		UUID of a Filter entity to apply to the Tag list. The Filter must be in the same Organization as the user credentials. The Filter's From field must match the entity type being filtered (Tag). For Space-resident entities, if the Filter has a FromSpaceID, it must match the operation's SpaceID. The Filter's Where clause will be combined with any explicit 'where' parameter using AND logic. If both 'filter' and 'where' parameters are specified, they are combined with AND logic.
contains	string		Free text search that approximately matches the specified string against string fields and map keys/values. The search is case-insensitive and uses pattern matching to find entities containing the text. Searchable string fields include attributes like Slug, DisplayName, and string-typed custom fields. For map fields (like Labels and Annotations), the search matches both map keys and values. The search uses OR logic across all searchable fields, so matching any field will return the entity. If both 'where' and 'contains' parameters are specified, they are combined with AND logic. Searchable fields for Tag include string and map-type attributes from the queryable attributes list. The whole string must be query-encoded.
include	string		Include clause for expanding related entities in the response for Tag. The attribute names are case-sensitive, PascalCase, and expected in a comma-separated list format as in the JSON encoding. Supported attributes for Tag are ChangeSetID, OrganizationID, SpaceID. The whole string must be query-encoded.
