SAP Fieldglass

This page records how composerID publishes into SAP Fieldglass: the vendor’s API posture, the publish target and field mapping, and the documentation each claim rests on. It is for anyone evaluating the connection or building against it. SAP Fieldglass is a structured, enterprise VMS used to manage large external workforces and SOW services at global scale. composerID turns Triage intent into deterministic Fieldglass records (requisitions, SOW and time objects) handling tenant-specific requirements via preflight and enrichment.

Category: Vendor Management & Sourcing. Coverage status: Specification mapped. Vendor documentation: public developer portal.

Integration path

How composerID connects to this destination, at a glance.

Step	Detail
Authentication	OAuth 2.0 (client credentials; SAML and X.509 assertion flows also supported).
composerID publishes	Requisition (Contingent): REST resource (tenant-specific)
Intent ID lands on	`job_posting` `customFields.intentId`, written into the destination record
Back-sync	Polling: the destination publishes no events composerID can subscribe to, so state is read back on a schedule.

API posture

Aspect	Detail
Authentication	OAuth 2.0 (client credentials; SAML and X.509 assertion flows also supported). Credentials and application keys provisioned per tenant/environment.
Style	REST (JSON) + OData; upload/download connectors also accept CSV. 227+ individual REST resources across requisitions, work orders, time sheets and SOW.
Base URL	Tenant + environment specific (provisioned per Fieldglass instance). No single public base URL.
Webhooks	Poll-first. Outbound integration connectors and audit-trail downloads are configured per tenant; no general public webhook bus.
Events posture	Polling
Rate limits	100 requests/second per API by default; burst to 200 req/s for short durations.
Objects	Job Posting / Requisition, Work Order + revisions, Worker, Time Sheet, Expense, SOW, Invoice, Supplier

Publish target and field mapping

Each object below pairs the canonical intent fields with the destination’s own fields and operations. The mapping is indicative until it is confirmed against a tenant at onboarding.

Requisition (Contingent)

Create external worker request

Mapping	Detail
Canonical to destination	role_title, location, start_date, cost_center, worker_type
Target	REST resource (tenant-specific)
Requirement	Required + tenant required
Notes	Preflight enforces required fields

Statement of Work

Create services request / SOW

Mapping	Detail
Canonical to destination	service_category, sow.summary, deliverables[], budget, dates
Target	REST resource (tenant-specific)
Requirement	Often tenant required
Notes	Attach Compliance File where supported

Timesheet

Capture time entries

Mapping	Detail
Canonical to destination	worker_id, period, hours, cost_center
Target	REST resource (tenant-specific)
Requirement	Required
Notes	Back-sync recommended

Intent ID correlation

Carry the Intent ID

Mapping	Detail
Canonical to destination	intent_id, intent_version
Target	CustomField.IntentID on the Job Posting / Work Order
Requirement	Required
Notes	Matches the fieldglass.contingent_requisition.v1 mapping profile; concrete custom-field key confirmed at tenant onboarding

Some Fieldglass requirements are program/tenant-defined (custom fields, approval chains, code lists). Even with public PDFs, a tenant connection is needed to confirm required fields and generate a tenant-specific MappingProfile. Legacy SAP landscapes may route via BAPIs/RFCs/IDocs rather than modern REST: confirm the integration path per tenant.
