Infor CloudSuite and Plaid integration

What moves between them

Bank transactions from Plaid flow into Infor CloudSuite as cash receipts and transaction records in the general ledger. When a Plaid transaction matches a CloudSuite AP invoice by amount and supplier, the invoice is marked as matched to accelerate cash application. Payment batches created in CloudSuite - typically for supplier invoices due or payroll distributions - are read from CloudSuite, extracted as ACH transfer instructions, and initiated through Plaid's transfer API. Bank account and balance information from Plaid is also synced into CloudSuite's bank reconciliation records. The flow is pull-initiated from CloudSuite with Plaid webhooks for urgent updates.

How ml-connector handles it

ml-connector stores Plaid API credentials (client_id, secret) encrypted and each CloudSuite tenant's .ionapi file (which contains the unique base URL and OAuth endpoints). On the CloudSuite side, it polls the AP and GL transaction APIs for new records and payment batches, extracting supplier and amount data to construct Plaid transfer calls. On the Plaid side, it receives webhook notifications of new transactions via JWT-signed HTTP POST, validates the JWT using Plaid's JWK public key and iat claim, and decodes the transaction details. When matching an AP invoice to a Plaid transaction, ml-connector compares supplier routing number (from Plaid auth.numbers), invoice amount, and date within a configured tolerance window. For ACH transfers initiated from CloudSuite payment batches, ml-connector calls Plaid's transfer/create endpoint with the supplier's account information resolved from prior Plaid auth queries, includes an idempotency key to prevent re-submission on retries, and tracks transfer status via Plaid webhooks. If a transfer is rejected by the bank (network error, account closed), ml-connector posts an exception record to CloudSuite's audit log and halts the batch. Bank reconciliation from Plaid transactions is refreshed daily and compared against CloudSuite's bank account master records.

A real-world example

A mid-sized consumer products company runs Infor CloudSuite Financials for AP, GL, and cash management across three regional bank accounts. Before the integration, the accounting team received daily bank statements from their bank portal, manually downloaded transaction lists, and re-entered deposits and wire payments into CloudSuite by hand - a process that took 4 to 6 hours per week and produced matching errors. With Plaid and CloudSuite connected, each day's bank transactions automatically appear in CloudSuite as cash receipts, matched against customer invoices by amount, and the team can initiate ACH payments for approved AP invoices directly from CloudSuite, with status flowing back as the transfer clears the bank. Month-end cash application now takes 30 minutes instead of a day, and re-keying errors have dropped to zero.

What you can do

• •Sync bank transactions from Plaid into Infor CloudSuite as cash receipts and GL postings, matched to customer invoices by amount and date.
• •Initiate ACH transfers from CloudSuite payment batches through Plaid, with idempotency keys to prevent double-submission.
• •Match Plaid bank data to CloudSuite accounts payable invoices by supplier routing number and amount, accelerating cash application.
• •Handle Plaid's JWT webhook signatures and CloudSuite's per-tenant OAuth credentials and unique base URLs without manual reconfiguration.
• •Track bank reconciliation from Plaid and compare against CloudSuite's GL bank account records, flagging discrepancies in the audit log.

Questions

How does the integration match Plaid bank transactions to Infor CloudSuite invoices?

ml-connector compares the supplier bank account routing number from Plaid's auth.numbers field against the supplier master in CloudSuite, then matches the transaction amount and posting date within a configurable tolerance window (typically same-day or +/- 2 days). When a match is found, the AP invoice is marked as applied and the transaction is posted to the GL cash receipt account.

Does ml-connector handle Plaid's JWT signature verification and webhook retries?

Yes. ml-connector validates every webhook using Plaid's JWK public key, enforces ES256 algorithm, checks the iat claim is within 5 minutes of the current time, and computes SHA-256 of the raw request body to verify against the request_body_sha256 claim. It returns 200 within 10 seconds and handles Plaid's exponential backoff retries for up to 24 hours.

What happens if a CloudSuite payment batch initiated as a Plaid ACH transfer is rejected?

ml-connector immediately posts an exception record to CloudSuite's audit log with the transfer ID and rejection reason, halts the batch from further processing, and notifies the finance team via the CloudSuite dashboard. The payment remains in CloudSuite for resubmission after the blocking issue is resolved.
