Oracle Fusion Cloud ERP and Procore integration

What moves between them

The main flow runs in both directions. Suppliers and general ledger accounts from Oracle Fusion are synced to Procore to establish vendors and cost codes, ensuring Procore project costs land on valid GL accounts. Purchase orders and requisitions flow from Procore into Oracle Fusion for AP matching and accrual accounting. Project costs, change orders, and direct costs from Procore feed into Oracle Fusion's journal entries, posted to the project cost center and GL account mapped during setup. This two-way sync runs on a schedule tied to your project closeout and accounting calendar.

How ml-connector handles it

ml-connector stores both credential sets encrypted and handles the session-scoped pod URL that Oracle Fusion assigns to each customer, since Oracle publishes no shared base hostname. It polls Oracle Fusion on the configured schedule using LastUpdateDate filters to detect invoices, suppliers, and GL changes, and it receives Procore's webhook notifications in real time when commitments or costs change. For every Procore call, ml-connector includes the required company_id and project_id in the request path. Bearer tokens are refreshed when calls return 401. Suppliers are mapped to Procore vendors, purchase orders are matched by external reference, and project costs are tagged with the GL account and cost center they belong in Oracle Fusion. Procore webhooks must acknowledge within 5 seconds, so ml-connector queues the payload immediately and processes it asynchronously. Oracle Fusion's PATCH operations on invoices only update header attributes, so cascade defaulting does not fire; ml-connector handles account combinations and cost allocations explicitly. Every record carries a full audit trail and can be replayed if a downstream GL post fails.

A real-world example

A mid-sized construction company manages projects in Procore and runs Oracle Fusion Cloud ERP for accounting and supplier management. Before the integration, the finance team exported supplier lists from Oracle Fusion and manually created matching vendors in Procore, then extracted project costs from Procore each month and spent hours matching them back to supplier invoices and cost centers in Oracle Fusion. Reconciliation was error-prone and month-end close was delayed. With Oracle Fusion and Procore connected, suppliers sync automatically, purchase orders and project costs flow into Oracle Fusion without re-entry, and the GL accounts are pre-allocated by project. Month-end close starts with the project costs already in the ledger and matched to the correct suppliers and cost centers.

What you can do

• •Sync suppliers from Oracle Fusion to Procore vendors, and cost codes from Oracle Fusion GL accounts to Procore budget setup.
• •Pull purchase orders and requisitions from Procore into Oracle Fusion for AP accrual and commitment tracking.
• •Post project costs and change orders from Procore into Oracle Fusion's general ledger, allocated to the correct cost centers and GL accounts.
• •Authenticate Oracle Fusion with OAuth 2.0 against customer-specific pod URLs, and Procore with OAuth 2.0 client credentials and required company and project IDs.
• •Poll Oracle Fusion on a configurable schedule, receive Procore webhooks in real time, and maintain a full audit trail on every record for compliance and replay.

Questions

Which direction does data flow between Oracle Fusion and Procore?

Data flows in both directions. Suppliers and GL accounts move from Oracle Fusion to Procore to set up vendors and cost codes. Purchase orders and requisitions flow from Procore into Oracle Fusion for AP matching. Project costs and change orders move from Procore into Oracle Fusion's general ledger. This two-way sync ensures both systems stay aligned on commitments and project costs.

How does ml-connector handle Oracle Fusion's customer-specific pod URL?

Each Oracle Fusion customer has a unique pod URL assigned by Oracle. ml-connector accepts the full pod URL per customer and uses it for all Oracle API calls, since Oracle publishes no shared base hostname. The URL format is https://{pod}.fa.{region}.oraclecloud.com/fscmRestApi/resources/. This approach eliminates the need for a multi-tenant discovery service.

What happens when Procore webhooks arrive?

Procore webhooks arrive in real time when commitments, requisitions, or costs change. ml-connector receives the webhook, acknowledges it with a 2xx response within 5 seconds (as Procore requires), and queues the payload for asynchronous processing. This prevents webhook timeouts while ensuring reliable delivery and allowing time for downstream GL posting without blocking Procore's webhook retry logic.
