The CMDB Instance API provides endpoints to create, read, update, and delete operations on existing Configuration Management Database (CMDB) tables. You can only insert, update, or delete one record at a time.

This API requires the user have the ITIL role.

CMDB Instance - DELETE /now/cmdb/instance/{classname}/{sys_id}/relation/{rel_sys_id}

Deletes the relation for the specified configuration item (CI).

URL format

Versioned URL: /api/now/v1/cmdb/instance/{className}/{sys_id}/relation/{rel_sys_id}

Default URL: /api/now/cmdb/instance/{className}/{sys_id}/relation/{rel_sys_id}

Supported request parameters

CMDB Instance - GET /now/cmdb/instance/{classname}

Returns the available configuration items (CI) for a specified Configuration Management Database (CMDB) class (table).

URL format

Versioned URL: /api/now/v1/cmdb/instance/{className}

Default URL: /api/now/cmdb/instance/{className}

Supported request parameters

Table 7. Path parameters
Name Description
className CMDB class name. This is the name of the table that contains the desired CI records, such as cmdb_ci_linux_server or cmdb_ci_apache_web_server.

Data type: String
Table 8. Query parameters
Name Description
sysparm_limit Maximum number of records to return. For requests that exceed this number of records, use the sysparm_offset parameter to paginate record retrieval.

This limit is applied before ACL evaluation. If no records return, including records you have access to, rearrange the record order so records you have access to return first.

Note: Unusually large sysparm_limit values can impact system performance.

Data type: Number

Default: 10000
sysparm_offset Starting record index for which to begin retrieving records. Use this value to paginate record retrieval. This functionality enables the retrieval of all records, regardless of the number of records, in small manageable chunks.

For example, the first time you call this endpoint, sysparm_offset is set to "0". To simply page through all available records, use sysparm_offset=sysparm_offset+sysparm_limit, until you reach the end of all records.

Don't pass a negative number in the sysparm_offset parameter.

Data type: Number

Default: 0
sysparm_query Encoded query used to filter the result set. You can use a UI filter to obtain a properly encoded query.
Syntax: sysparm_query=<col_name><operator><value>.
  • <col_name>: Name of the table column to filter against.
  • <operator>: Supports the following values:
    • =: Exactly matches <value>.
    • !=: Does not match <value>.
    • ^: Logically AND multiple query statements.
    • ^OR: Logically OR multiple query statements.
    • LIKE: <col_name> contains the specified string. Only works for <col_name> fields whose data type is string.
    • STARTSWITH: <col_name> starts with the specified string. Only works for <col_name> fields whose data type is string.
    • ENDSWITH: <col_name> ends with the specified string. Only works for <col_name> fields whose data type is string.
    <value>: Value to match against.

All parameters are case-sensitive. Queries can contain more than one entry, such as sysparm_query=<col_name><operator><value>[<operator><col_name><operator><value>].

For example:

(sysparm_query=caller_id=javascript:gs.getUserID()^active=true)

Encoded queries also support order by functionality. To sort responses based on certain fields, use the ORDERBY and ORDERBYDESC clauses in sysparm_query.

Syntax:
  • ORDERBY<col_name>
  • ORDERBYDESC<col_name>

For example: sysparm_query=active=true^ORDERBYnumber^ORDERBYDESCcategory

This query filters all active records and orders the results in ascending order by number, and then in descending order by category.

If part of the query is invalid, such as by specifying an invalid field name, the instance ignores the invalid part. It then returns rows using only the valid portion of the query. You can control this behavior using the property glide.invalid_query.returns_no_rows. Set this property to true to return no rows on an invalid query.
Note: The glide.invalid_query.returns_no_rows property controls the behavior of all queries across the instance, such as in lists, scripts (GlideRecord.query()), and web service APIs.

CMDB Instance - POST /now/cmdb/instance/{classname}

Creates a single configuration item (CI) with the specified outbound and inbound relations within the specified Configuration Management Database (CMDB) table.

Note: If the CMDB class has a dependent identification rule defined, then the input payload must contain the sys_id of an existing CI. For example, for outbound_relations, the target parameter must contain the sys_id of an existing CI, which then becomes the child. For inbound_relations, it becomes the parent.
