Workday Financial Management is used by many of the world's largest organisations for HR and finance — it's particularly strong in the enterprise segment for payroll, procurement, and financial reporting. Its accounts receivable functionality is comprehensive but complex. TallyArc's Workday integration adds a client-facing billing layer that posts transactions back to Workday's AR module, keeping the Workday general ledger accurate without requiring finance teams to change their Workday workflows.
Workday integration model
Workday offers several integration frameworks. TallyArc uses the Workday REST API (available in Workday 2019R2+) for:
- Reading customer accounts from the Business Partner object
- Creating Customer Invoice business objects
- Posting Customer Payment business objects and applying them to open invoices
API and OAuth setup
- In Workday, navigate to Edit Tenant Setup — System → OAuth 2.0 Clients and register a new API client
- Select the Non-Expiring Refresh Tokens option and assign the following Workday scope: Financials, Business Assets
- Generate a refresh token for the integration user (a dedicated Workday System user with AR permissions)
- Note the Client ID, Client Secret, Workday hostname (e.g.
wd5-impl-services1.workday.com), and Tenant name - In TallyArc, go to ERP → Workday → Connect and enter these credentials
Workday data objects used
- Customer (Business Partner) — source of client data for TallyArc
- Customer Invoice — created in Workday when an invoice is issued in TallyArc; includes revenue lines, tax lines, and AR receivable line
- Customer Payment — created when payment is received in TallyArc; applied to the open Customer Invoice
- Revenue Category — maps to Workday revenue categories for GL posting
Worktag mapping
Workday's "worktag" system (Cost Centre, Project, Fund, Programme) is equivalent to GL dimensions in other systems. TallyArc supports worktag assignment on invoice lines — configure default worktags per client or per invoice category to ensure every transaction posts with the correct segment reporting tags.
Enterprise considerations
Workday integrations in enterprise environments typically require review by your Workday implementation partner or internal HRIS/ERP team. TallyArc provides technical integration documentation for IT review, and the integration can be tested in your Workday sandbox tenant before enabling in production.
