To query a resource collection, which you can think of as a resource container, perform an HTTP GET and accept a JSON response including at least a _queryFilter or _queryId parameter. These parameters cannot be used together.

GET /users?_queryFilter=true HTTP/1.1
Accept: application/json

The endpoint returns the result as a JSON object including a results array and other fields related to the query string parameters.


You can use the following query string parameters:

Parameter Description


Return only the specified fields in each element of the results.

The field values are JSON pointers. For example, if the resource is {"parent":{"child":"value"}}, parent/child refers to the "child":"value".

If the field is left blank, the endpoint returns all default values.


The string is an opaque cookie to keep track of the position in the search results. The service returns the cookie in the JSON response as the value of pagedResultsCookie.

In the request _pageSize must be set and non-zero. You receive the cookie value from the provider on the first request. You supply the cookie value in subsequent requests until the service returns a null cookie when the final page of results has been returned.

Use this parameter with the _queryFilter parameter. It is not guaranteed to work with the _queryId parameter.

The _pagedResultsCookie and _pagedResultsOffset parameters are mutually exclusive. Do not use them together.


When _pageSize is non-zero, use this as an index in the result set indicating the first page to return.

The _pagedResultsCookie and _pagedResultsOffset parameters are mutually exclusive. Do not use them together.


Return query results in pages of this size.

After the initial request, use _pagedResultsCookie or _pageResultsOffset to page through the results.


Format the body of the response.


Query filters request entries matching the filter expression. You must URL-escape the filter expression.

For details, refer to Filter expressions.


Specify a query by its identifier.

Specific queries can take their own query string parameter arguments depending on the implementation.


Sort the resources returned based on the specified field(s) in + (ascending, default) or in - (descending) order.

As ascending order is the default, including the ` character in the query is unnecessary. If you do include the `, it must be URL-encoded as %2B:


The _sortKeys parameter is not supported for predefined queries (_queryId).


When a non-zero _pageSize is specified, the service calculates the totalPagedResults in accordance with the totalPagedResultsPolicy, and provides the value as part of the response.

The totalPagedResults is:

  • An estimate of the total number of paged results (_totalPagedResultsPolicy=ESTIMATE).

  • The exact total result count (_totalPagedResultsPolicy=EXACT).

If no count policy is specified in the query, or if _totalPagedResultsPolicy=NONE, result counting is disabled. The service returns "totalPagedResults": -1.

Filter expressions

Query filters request entries matching the filter expression. You must URL-escape the filter expression.

The string representation is summarized as follows:

Expr           = OrExpr
OrExpr         = AndExpr ( 'or' AndExpr ) *
AndExpr        = NotExpr ( 'and' NotExpr ) *
NotExpr        = '!' PrimaryExpr | PrimaryExpr
PrimaryExpr    = '(' Expr ')' | ComparisonExpr | PresenceExpr | LiteralExpr
ComparisonExpr = Pointer OpName JsonValue
PresenceExpr   = Pointer 'pr'
LiteralExpr    = 'true' | 'false'
Pointer        = JSON pointer
OpName         = 'eq' |  # equal to
                 'co' |  # contains
                 'sw' |  # starts with
                 'lt' |  # less than
                 'le' |  # less than or equal to
                 'gt' |  # greater than
                 'ge' |  # greater than or equal to
                 STRING  # extended operator
JsonValue      = NUMBER | BOOLEAN | '"' UTF8STRING '"'
STRING         = ASCII string not containing white-space
UTF8STRING     = UTF-8 string possibly containing white-space

JsonValue components of filter expressions follow RFC 7159: The JavaScript Object Notation (JSON) Data Interchange Format. In particular, as described in section 7 of the RFC, the escape character in strings is the backslash character. For example, to match the identifier test\, use _id eq 'test\\'. In the JSON resource, the \ is escaped the same way: "_id":"test\\".

When using a query filter in a URL, notice the filter expression is part of a query string parameter. URL-encoded the filter expression. For details, refer to RFC 3986: Uniform Resource Identifier (URI): Generic Syntax. For example, whitespace, double quotes ("), parentheses, and exclamation characters need URL encoding. The following rules apply to URL query components:

query       = *( pchar / "/" / "?" )
pchar       = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims  = "!" / "$" / "&" / "'" / "(" / ")"
                  / "*" / "+" / "," / ";" / "="

ALPHA, DIGIT, and HEXDIG are core rules of RFC 5234: Augmented BNF for Syntax Specifications:

ALPHA       =  %x41-5A / %x61-7A   ; A-Z / a-z
DIGIT       =  %x30-39             ; 0-9
HEXDIG      =  DIGIT / "A" / "B" / "C" / "D" / "E" / "F"

As a result, a backslash escape character in a JsonValue component is percent-encoded in the URL query string parameter as %5C. To encode the query filter expression _id eq 'test\\', use _id+eq'test%5C%5C'+, for example.

A simple filter expression can represent a comparison, presence, or a literal value.

For comparison expressions use json-pointer comparator json-value, where the comparator is one of the following:

eq (equals)
co (contains)
sw (starts with)
lt (less than)
le (less than or equal to)
gt (greater than)
ge (greater than or equal to)

For presence, use json-pointer pr to match resources where:

  • The JSON pointer is present.

  • The value it points to is not null.

Literal values include true (match anything) and false (match nothing).

Complex expressions employ and, or, and ! (not), with parentheses, (expression), to group expressions.
