How does ml-connector handle PeopleSoft's self-hosted architecture?

ml-connector accepts the full PeopleSoft hostname, port, and node name as configuration per customer, since each PeopleSoft instance runs on unique infrastructure. It stores these credentials encrypted alongside the login credentials (HTTP Basic Auth or OAuth2 depending on PeopleTools version) and validates paths against that specific instance on every call.

Which direction do purchase orders and invoices flow between PeopleSoft and JAGGAER?

Purchase requisitions flow from PeopleSoft into JAGGAER for sourcing and supplier selection. Approved purchase orders then route from JAGGAER back to PeopleSoft for financial recording and expense allocation. Invoices received in JAGGAER are synced to PeopleSoft's accounts payable module.

What happens if PeopleSoft or JAGGAER returns an error during a sync?

ml-connector logs the full error response with the record ID and queues the record for replay. Because both systems use polling rather than webhooks, ml-connector can safely retry the failed record on the next scheduled sync cycle. The audit trail preserves the original error message for troubleshooting.

Oracle PeopleSoft and JAGGAER integration

Oracle PeopleSoft runs finance, procurement, and payroll across your enterprise. JAGGAER handles Source-to-Pay and supplier management. Connecting the two ensures purchase requisitions flow from PeopleSoft into JAGGAER for sourcing and buying, purchase orders route back to PeopleSoft for accounting, and invoices stay synchronized between both systems. ml-connector manages the very different authentication models and polling cadences on each side.

How Oracle PeopleSoft works

Oracle PeopleSoft exposes invoices, requisitions, purchase orders, vendors, GL accounts, job codes, and employee records through REST and SOAP endpoints. The platform runs self-hosted on customer infrastructure, so each customer has a unique hostname, port, and node name. Authentication uses HTTP Basic Auth (username and password) for all versions, or OAuth2 bearer tokens for PeopleTools 8.58 and later. PeopleSoft has no native webhooks but supports asynchronous publish-subscribe messages through Integration Broker, which can push XML to external endpoints when configured by a PeopleSoft administrator. Most integrations poll with date-range filters to avoid performance impact on the customer's system.

How JAGGAER works

JAGGAER provides Source-to-Pay and supplier management through the J1P REST API, which serves invoices, purchase orders, vendors, contracts, and catalog items from a cloud SaaS instance. It also supports cXML (Commerce XML) for bidirectional document exchange and iDoc feeds for ERP systems. Authentication uses OAuth2 client credentials provisioned during onboarding, with a token endpoint specific to the customer's JAGGAER instance. JAGGAER is primarily pull-based via the J1P API; event-driven push configuration is available but requires JAGGAER professional services. The platform enforces no published rate limits, but connections are stable and well-documented through customer-gated Swagger specs.

What moves between them

Purchase requisitions flow from PeopleSoft into JAGGAER so procurement teams can source and quote suppliers. Purchase orders created in JAGGAER route back to PeopleSoft for financial recording and expense allocation. Invoices received in JAGGAER are synced to PeopleSoft's accounts payable module. Vendor master records align in both directions so purchase orders and invoices reference valid suppliers in PeopleSoft. The sync runs on a schedule aligned to your procurement cycle, typically daily or on demand when critical documents arrive.

How ml-connector handles it

ml-connector stores PeopleSoft hostname, port, node name, and authentication credentials encrypted, and stores JAGGAER instance URL and OAuth2 client credentials separately encrypted. It accepts PeopleSoft Basic Auth credentials or OAuth2 tokens depending on the customer's PeopleTools version. On the JAGGAER side, it refreshes the OAuth2 bearer token before each call, since JAGGAER tokens expire. Because both systems are pull-only (PeopleSoft through polling, JAGGAER via REST only), ml-connector polls both on your schedule, filtering by date range on PeopleSoft to avoid scanning every historical record. Vendors and GL accounts are mapped first, so requisitions and invoices reference valid cost centers in both systems. PeopleSoft error responses are often cryptic, so ml-connector logs the raw response body for audit trails. Every record carries a full audit log and can be retried if a downstream call fails.

A real-world example

A mid-sized industrial products company runs Oracle PeopleSoft for finance, procurement, and payroll across three divisions and uses JAGGAER for strategic sourcing and spend management. Before the integration, procurement teams entered purchase requisitions in PeopleSoft, then manually recreated them in JAGGAER for supplier sourcing and quoting. Once JAGGAER purchase orders were approved, the finance team re-entered them into PeopleSoft's accounts payable module to match invoices. Vendor master data was maintained in both systems, causing mismatches when a supplier name changed or a new vendor was added. With PeopleSoft and JAGGAER connected, requisitions flow directly into JAGGAER for sourcing, orders return to PeopleSoft automatically for accounting, and vendor records stay aligned. Manual re-entry is eliminated, and procurement and finance teams work from a single source of truth.

What you can do

Sync purchase requisitions from Oracle PeopleSoft into JAGGAER for supplier sourcing and quoting.
Route approved purchase orders from JAGGAER back into PeopleSoft for accounts payable and GL posting.
Keep vendor master records aligned between both systems so purchases reference valid suppliers.
Authenticate PeopleSoft with HTTP Basic Auth or OAuth2 depending on your PeopleTools version, and handle JAGGAER OAuth2 refresh automatically.
Poll both systems on a schedule you control, with full audit trails and the ability to replay failed records.
