TallyPrime and Workday HCM integration

What moves between them

Payroll vouchers and expense entries from TallyPrime are polled on a configurable schedule and posted to Workday's GL accounts, mapped to the matching Workday cost centers and organizations. Worker and cost center master data flows in both directions so Workday's organizational structure reflects TallyPrime's accounts and department assignments. GL postings are read from TallyPrime and written to Workday; Workday's payroll and worker data is read as reference for validation but not overwritten. The polling cadence is tied to your payroll and close schedule rather than real-time, typically weekly or at period-end.

How ml-connector handles it

ml-connector maintains TallyPrime's local-network credentials and Workday's OAuth2 refresh token, presenting the correct authentication on each request to the respective API surface. On the TallyPrime side, it sends XML Export requests to the Day Book with date range filters and compares returned voucher IDs against last-seen state to detect new or changed records. TallyPrime requires sequential requests and the company to be loaded, so ml-connector serializes requests and includes company name in every envelope. On the Workday side, it uses the SOAP API to access GL accounts and cost centers for validation and write accounting journals. Workday access tokens expire in 60 minutes, so ml-connector refreshes the refresh token when a call returns 401. Because TallyPrime runs on a local machine, a local agent must bridge the cloud connector to port 9000; this agent is installed and configured per customer. Cost centers, organizations, and GL accounts are mapped and validated first, so every posted journal references a real Workday dimension. Rate limiting and retries are handled transparently.

A real-world example

A mid-sized services company in India uses TallyPrime for accounting and GST compliance, and uses Workday HCM for payroll and benefits across multiple offices. Before the integration, the accounting team exported payroll summaries from TallyPrime each month, manually creating journal entries in Workday to record payroll expense allocation by cost center and business unit. With TallyPrime and Workday HCM connected, monthly payroll vouchers flow automatically from TallyPrime into Workday's GL, allocated to the correct cost center and organization for each office. The manual journal entry step is eliminated, and the payroll GL is ready on the first day of close rather than days later.

What you can do

• •Poll TallyPrime's Day Book on a schedule you control and post summarized payroll expense vouchers to Workday's general ledger.
• •Map TallyPrime ledgers and groups to Workday GL accounts and cost centers, ensuring every journal line hits a valid dimension.
• •Authenticate TallyPrime via local-network credentials and company name, and Workday via OAuth2 with automatic token refresh.
• •Require a local agent to bridge the cloud connector to TallyPrime's port 9000, keeping credentials and data on the LAN.
• •Maintain a full audit trail of every voucher read and posted, with error replay if a write to Workday fails.

Questions

Does the integration require any setup on the TallyPrime side?

Yes. Port 9000 must be manually enabled in TallyPrime Advanced Configuration, and the target company must remain loaded while the integration runs. ml-connector connects via HTTP POST to the local port, not to a cloud instance, so a local agent running on the same LAN is required. Optional company-level credentials can be stored if the company is password-protected.

Which direction does data move between TallyPrime and Workday HCM?

The primary flow is TallyPrime into Workday. Payroll and expense vouchers are read from TallyPrime and posted to Workday's GL as accounting journals, allocated to cost centers and organizations. Worker and cost center master data is aligned in both directions so Workday's organizational structure matches TallyPrime's chart of accounts. Workday's payroll and worker records are read as reference data for validation but are not overwritten.

What happens when Workday's access token expires?

Workday REST and SOAP access tokens expire in 60 minutes. ml-connector monitors for 401 responses and automatically refreshes the token using the long-lived refresh token stored at setup. If the refresh token itself expires or is revoked, ml-connector will surface the error and pause until the credential is renewed.
