Zoho Books and AvidXchange integration

What moves between them

Vendor master data moves from Zoho Books into AvidXchange to keep the vendor list current. Purchase orders and new invoices created in Zoho Books are pushed to AvidXchange for AP approval workflow. Approved invoices flow from AvidXchange back into Zoho Books as bills, and completed payments return as vendor payments. GL codes and accounting dimensions are synchronized in both directions so invoice approvals land on the correct GL accounts.

How ml-connector handles it

ml-connector manages OAuth2 tokens for Zoho Books and resolves the correct regional base URL (US, EU, India, Australia, Japan, Canada, China, or Saudi Arabia) based on the customer's region credential. Every Zoho Books API call includes the required organization_id query parameter, resolved once at setup. On the AvidXchange side, it authenticates using the company_id-scoped OAuth2 client credentials provided via the Partner API. Since AvidXchange has no webhook support, the connector polls vendor updates and payment status on a schedule tied to your AP close and payment calendar. Vendor and GL dimension mappings ensure that when AvidXchange approves an invoice, it carries the correct Zoho Books GL account and cost center. The connector respects Zoho's 100 requests-per-minute rate limit and the 1-hour access token expiry, refreshing proactively to avoid outages. Every vendor, invoice, and payment record carries a full audit trail.

A real-world example

A mid-sized manufacturing company runs Zoho Books for accounting and procurement across multiple regions, and uses AvidXchange to manage accounts payable approvals and payment processing. Before the integration, the AP team manually entered vendor approval decisions from AvidXchange back into Zoho Books as bill records, then matched payment confirmations by hand. With Zoho Books and AvidXchange connected, vendors created in Zoho Books appear in AvidXchange automatically, approved invoices return as bills in Zoho, and completed payments post to Zoho's vendor payment ledger without re-keying. The AP team spends less time on data entry and reconciliation, and the general ledger stays synchronized with payment status.

Questions

Which direction does data move between Zoho Books and AvidXchange?

The main flow is bidirectional. Vendors and purchase orders move from Zoho Books into AvidXchange for approval. Approved invoices and completed payments then flow from AvidXchange back into Zoho Books as bills and vendor payments. GL codes and accounting dimensions synchronize in both directions so invoices land on valid GL accounts.

How does the integration handle Zoho Books regional URLs and organization IDs?

ml-connector stores the region for each customer's Zoho Books instance and routes all API calls to the correct regional base URL (US, EU, India, Australia, Japan, Canada, China, or Saudi Arabia). The organization ID is resolved once during setup and passed as a required query parameter on every Zoho Books API call.

Does AvidXchange support webhooks for real-time payment notifications?

No, AvidXchange does not support webhooks. ml-connector polls vendor lists and payment status on a schedule aligned with your AP close and payment calendar. This approach works well for finance teams with predictable payment cycles and avoids the need to maintain a webhook endpoint.
