How does the integration handle Oracle E-Business Suite's customer-hosted Integrated SOA Gateway?

Each customer provides their own ISG hostname and port since Oracle E-Business Suite publishes no fixed base URL. ml-connector stores the full ISG endpoint, port, and HTTP Basic Auth credentials encrypted, then includes required application context headers such as ctx_orgid and ctx_responsibility with each request based on your configuration. When the session token expires after the Oracle E-Business Suite timeout window, ml-connector re-authenticates automatically.

In what direction does payroll data flow between Oracle E-Business Suite and Deel?

Payroll GL postings and cost records flow from Oracle E-Business Suite into Deel accounting feeds. Payroll adjustments and bonuses are written to Deel when Oracle E-Business Suite cost changes occur. Cost centers and GL dimensions are synchronized in both directions so payroll allocations reference valid entities in both systems.

What happens when Oracle E-Business Suite's concurrent programs delay the import of interface records?

ml-connector tracks the import status of Oracle E-Business Suite interface records and waits for the concurrent program to complete before sending the corresponding Deel accounting entry. This prevents Deel from receiving incomplete or invalid cost allocations and ensures both systems stay in agreement.

Oracle E-Business Suite and Deel integration

Oracle E-Business Suite runs your enterprise finance, procurement, and manufacturing. Deel manages your global workforce, contracts, and payroll. Connecting the two keeps your labor costs synchronized with your GL and ensures Deel payroll inputs align with your cost center structure. Payroll GL postings flow from your Oracle E-Business Suite GL into Deel accounting feeds on a schedule you control, and employee cost allocations stay in agreement across both systems.

How Oracle E-Business Suite works

Oracle E-Business Suite exposes integrations through the Integrated SOA Gateway (ISG), a customer-deployed REST and SOAP web service layer. Each customer hosts their own ISG at a unique hostname and port with no fixed base URL. The API authenticates with HTTP Basic Auth credentials or a session token cookie obtained via the login endpoint. Key entities include accounts payable invoices, purchase orders, GL code combinations, journal entry headers and lines, vendors, customers, and inventory items. Oracle E-Business Suite has no modern webhook system, so records are retrieved by polling the open interface views filtered by last update date with limit and offset pagination. Session tokens expire based on the EBS timeout, typically 30 to 60 minutes, and concurrent programs that write to interface tables may take minutes to hours to complete validation and import.

How Deel works

Deel is a global workforce and payroll platform covering contractor management, employee contracts, HRIS, and compliance across 150 plus countries. It exposes contracts, people, invoices, payslips, and payroll inputs through REST JSON APIs at a fixed endpoint. Authentication uses Bearer tokens or OAuth2 Authorization Code Grant, with API tokens either organization-scoped with no expiry or personal tokens with 30-day OAuth access tokens. Deel publishes real-time webhooks for contract creation, employee changes, and terminations with HMAC-SHA256 signature verification. The API supports write operations on payroll inputs such as bonuses and deductions. API token scopes are defined at creation time and grant fine-grained access to contracts, accounting, and people resources. Pagination is offset-based with a default limit of 25 records, and idempotency keys are supported on POST and PATCH operations.

What moves between them

The primary flow moves payroll GL postings and cost data from Oracle E-Business Suite into Deel accounting feeds. Payroll expense GL lines from Oracle E-Business Suite journal entries are polled on a schedule tied to your payroll calendar, then mapped to Deel invoices and cost allocations. Payroll inputs such as bonuses and deductions are written to Deel when Oracle E-Business Suite cost adjustments occur. Employee cost centers and departments are synchronized in both directions so payroll allocations land on valid GL dimensions in Oracle E-Business Suite and cost records in Deel remain aligned.

How ml-connector handles it

ml-connector stores the Oracle E-Business Suite ISG hostname, port, and credentials encrypted, then authenticates with HTTP Basic Auth on each API call. When a session token expires after the Oracle E-Business Suite timeout window, ml-connector receives a 401 response and re-authenticates transparently. Application context headers required by Oracle E-Business Suite, such as ctx_orgid and ctx_responsibility, are included with each request based on your customer configuration. Deel authentication uses a Bearer token or OAuth2 access token; ml-connector refreshes OAuth2 tokens before they expire and detects Deel API rate limits by inspecting the Retry-After header on 429 responses. Deel webhook signatures are verified using HMAC-SHA256 on the raw request body before parsing JSON, so signature validation happens first. Oracle E-Business Suite is pull-only, so ml-connector polls payroll GL postings and cost records on your defined schedule rather than waiting for a push. Payroll GL lines are mapped to Deel cost centers by matching the Oracle E-Business Suite GL code combinations and cost center values, ensuring every allocation references a valid Deel entity. Because Oracle E-Business Suite writes to interface tables asynchronously via concurrent programs, ml-connector tracks the import status and delays downstream Deel writes until the Oracle E-Business Suite interface record confirms completion. Every record carries a full audit trail with timestamps, credential scope, API call details, and response status.

A real-world example

A mid-sized technology services company runs Oracle E-Business Suite on premises for finance and project accounting, and uses Deel to manage contractors and full-time employees across five countries. Before the integration, the finance team exported payroll cost registers from Deel every month, manually matched them to Oracle E-Business Suite project cost centers, and re-entered labor totals into the GL by hand. Month-end close was delayed because payroll GL postings arrived late and cost allocations often mismatched the GL structure, forcing reconciliation by hand. With Oracle E-Business Suite and Deel connected, payroll GL postings flow automatically into the GL on your payroll calendar, allocated to the correct project cost center for each employee, and employee cost records stay synchronized in both systems. Month-end close starts with payroll costs already reconciled to the GL, and the manual re-keying step is eliminated.
