Squid vs ServiceNow TableAPI: A Detailed Comparison

This page provides an in-depth technical comparison between Squid and ServiceNow's native TableAPI, using a real-world data request as an example.

The Challenge​

Let's compare how ServiceNow TableAPI and Squid solve the following data request:

Give me all relevant data on a specific laptop, including:

  • Asset information
  • Assigned user with their full details and location
  • CI location
  • Manufacturer
  • Model
  • Application Services this CI is used by
  • Network ports with name and netmask

The Score: Squid 1 — TableAPI 11​

Squid satisfies this request with one HTTP request returning a complete JSON.

ServiceNow TableAPI requires eleven request/response cycles plus client-side logic to achieve the same result.

Squid vs TableAPI ComparisonThis diagram compares how Squid and ServiceNow TableAPI handle the same data request: retrieving comprehensive laptop data with all related entities including asset, assigned_to, location, manufacturer, model, used_by services, and network ports. SQUID (Left Panel - 1 Request): Squid accomplishes this with a single HTTP GET request to /api/x_a46gh_squidx/v1/data/cmdb_ci_pc_hardware_full_inline with encodedQuery and relations parameters. The response includes all data in one JSON: asset, assigned_to, location, manufacturer, model_id, used_by[], network_ports[], plus nested references like assigned_to.location and model_id.manufacturer. Advantages of Squid: - Zero client-side logic required - Recursive reference resolution - Single network round-trip - Pre-built configurations TABLEAPI (Right Panel - 11 Requests): ServiceNow TableAPI requires 11 separate requests plus client-side logic: 1. Initial Request to cmdb_ci_pc_hardware 2. Asset lookup to alm_hardware 3. Assigned To lookup to sys_user 4. User Location lookup to cmn_location 5. CI Location lookup to cmn_location 6. Manufacturer lookup to core_company 7. Model lookup to cmdb_model 8. Relations query to cmdb_rel_ci 9. Parent CI lookup to cmdb_ci 10. Service lookup to cmdb_ci_service_auto 11. Network Ports query to cmdb_ci_network_adapter Challenges with TableAPI: - Client must parse and extract links from each response - Multiple network round-trips add latency - Must know relation sys_ids in advance - Manual table targeting required BOTTOM LINE COMPARISON: - Squid: 1 request, 0 client logic operations - TableAPI: 11 requests, 10+ parse operations Score: Squid:1 — TableAPI:11 Retrieving comprehensive laptop data with all related entities 1SquidSingle RequestHTTP GET Request/api/.../data/cmdb_ci_pc_hardware_full_inline?encodedQuery=...&relations=used_by,network_portsComplete JSON Response✓ asset✓ assigned_to✓ location✓ manufacturer✓ model_id✓ used_by✓ network_ports✓ user_location+ Nested: assigned_to.location, model_id.manufacturerAdvantages• Zero client-side logic• Recursive reference resolution• Single network round-trip• Pre-built configurationsOne request.

The Request Cascade​

The following diagram illustrates the cascade of requests required when using TableAPI to resolve references and relations.

TableAPI: The Request CascadeThis diagram visualizes the complexity of using ServiceNow TableAPI to retrieve comprehensive data. It shows the 11 HTTP requests required, the useless JSON responses with link/value pairs, and the arcane knowledge needed. KEY PAIN POINTS: TableAPI returns references as {"link": "...", "value": "sys_id"} with no actual data. The initial response contains 80+ fields, most empty. Each response must be parsed, links extracted, and followed with new requests. Nested references (user→location) multiply requests. Relations require knowing magic sys_ids. Generic table responses force re-querying with the correct table. TOTAL: 11 requests, 10+ parse operations, ~1.1s network time, 80+ unused fields, 100+ lines of client code.TableAPI: The Request CascadeYOUR CODESERVICENOW1GET /api/now/table/cmdb_ci_pc_hardware?sysparm_query=name=w010y7Response: 80+ fields, references are just link/value pairs"manufacturer": {"link": "https://.../core_company/aa0a6df8...", "value": "aa0a6df8..."}"assigned_to": {"link": "https://.../sys_user/c8b1c7a4...", "value": "c8b1c7a4..."}"floppy": "", "cd_speed": "", "os_service_pack": "" ... ← No data, just links!const assetUrl = ci.asset?.link; // might be null!2GET /api/now/table/alm_hardware/{sys_id}const userUrl = ci.assigned_to?.link; // check if exists3GET /api/now/table/sys_user/{sys_id}↑ User has a location reference → need ANOTHER request!const userLocUrl = user.location?.link; // NESTED!

Squid Approach​

Squid uses configurations that define how entities are rendered. A single request returns all data with references recursively resolved.

The Request​

https://yourinstance.service-now.com/api/x_a46gh_squidx/v1/data/cmdb_ci_pc_hardware_full_inline?encodedQuery=base_name=w010y7&relations=used_by_service,network_ports_inline
Squid GET Request StructureThis diagram illustrates the anatomy of a Squid GET request, breaking down a complete URL into its component parts and showing the three categories of query parameters available. URL ANATOMY - A Squid request consists of four main parts shown with color coding: 1. BASE PATH (gray): /api/x_a46gh_squidx/v1/data/ - The Squid API endpoint, fixed for all requests 2. CONFIGURATION (cyan): e.g., cmdb_ci_pc_hardware_full_inline - Determines database view, available fields, reference handling, and relation definitions. 3. FILTER PARAMETERS (purple): encodedQuery - Restrict which records are returned 4. RELATION PARAMETERS (red): relations - Request related data to be included QUERY PARAMETER CATEGORIES: FILTERS (restrict what data returns): - encodedQuery: ServiceNow encoded query syntax with base_ prefix for base table fields - sys_id: Retrieve specific records by sysId (comma-separated or repeated parameter) - limit: Maximum number of entities to return - updatedSince/updatedBefore: Filter by sys_updated_on timestamp (ISO8601) - filterOnTags: Filter by cmdb_key_value entries (tagName=value syntax) - filterOnTeams: Filter by cmdb_rel_team entries (team assignments) RELATIONS (request related data): - relations: Comma-separated list of relation names to resolve (e.g., used_by_service, network_ports) - {config}.relations: Request relations for specific referenced entities when using inline rendering FLAGS (toggle features): - showBlank: Include properties with null values (normally suppressed) - showTags: Include tags/key-value data (options: object or array format) - showTagsInline: Render tags directly in entity objects - showConfig: Add squid_config property showing which config rendered each entity - metaData: Include extended timing and cache statistics in response metadata - lenient: Non-strict error handling (warnings instead of errors) - development only - preservePrefix: Keep database view column prefixes (base_, lin_, etc.)/api/x_a46gh_squidx/v1/data/cmdb_ci_pc_hardware_full_inline?encodedQuery=...&relations=...ConfigurationFilter paramRelation paramFlag paramQUERY PARAMETER CATEGORIESFILTERSencodedQueryServiceNow query syntaxsys_idSpecific records by sysIdlimitMax entities to returnupdatedSince/BeforeFilter by sys_updated_onfilterOnTagsFilter by key-value entriesfilterOnTeamsFilter by team assignmentsRestrict dataRELATIONSrelationsComma-separated list ofrelation names to resolve{config}.relationsRequest relations forspecific referenced entitiesSupported Types:• CMDB relations• 1-to-N relations• M-to-N via junction tablesAdd related dataFLAGSshowBlankInclude null valuesshowTagsInclude key-value datashowTagsInlineTags in entity objectsshowConfigShow rendering configmetaDataExtended timing infolenientWarnings vs errorspreservePrefixKeep column prefixesUsage:Flags are boolean - just includethe parameter name:?showTags&metaDataToggle features

Request Components​

cmdb_ci_pc_hardware_full_inline​

The requested configuration.

By convention, most predefined configurations align with ServiceNow tables. full_inline indicates we want all data inlined rather than referenced.

encodedQuery​

Restricts the result set using any valid ServiceNow encodedQuery (with some restrictions).

relations​

Specifies which relations to resolve:

  • used_by_service — adds any cmdb_ci_service referencing this CI via Depends On::Used by
  • network_ports_inline — adds any cmdb_ci_network_adapter referencing this CI

TableAPI Approach​

The ServiceNow TableAPI will eventually give you all the data Squid provides — it just requires significantly more work.

The Request​

https://yourinstance.servicenow.com/api/now/table/cmdb_ci_pc_hardware?sysparm_query=name%3Dw010y7

Limitations​

No Reference Resolution​

TableAPI renders references as links, not data:

{
  "manufacturer": {
    "link": "https://yourinstance.servicenow.com/api/now/table/core_company/aa0a6df8c611227601cd2ed45989e0ac",
    "value": "aa0a6df8c611227601cd2ed45989e0ac"
  }
}

Every reference requires an additional HTTP request to resolve.

Display Value Option​

Using sysparm_display_value=true provides display values:

{
  "manufacturer": {
    "display_value": "Lenovo",
    "link": "https://yourinstance.servicenow.com/api/now/table/core_company/aa0a6df8c611227601cd2ed45989e0ac"
  }
}

But display values are UI-dependent and ambiguous — not suitable for reliable integrations.

Verbose Output with sysparm_display_value=all​

{
  "os_service_pack": {
    "display_value": "",
    "value": ""
  },
  "cpu_core_thread": {
    "display_value": "",
    "value": ""
  },
  "cpu_manufacturer": {
    "display_value": "",
    "value": ""
  }
}

Highly verbose without additional value.

No Native Relation Resolution​

To find services associated with the laptop, you must query cmdb_rel_ci explicitly:

https://yourinstance.servicenow.com/api/now/table/cmdb_rel_ci?sysparm_query=child%3D940b0cff873379d06dc863540cbb355e%5Etype%3D1a9cb166f1571100a92eb60da2bce5c5

This returns relation records, not the actual service data — requiring yet another request.
