Infor CloudSuite and Twilio integration

What moves between them

Procurement alerts flow from Infor CloudSuite to Twilio. ml-connector polls CloudSuite's invoice and purchase order APIs on a configurable schedule, retrieves newly created or updated records, and routes relevant alerts to Twilio as SMS messages or voice calls. A new supplier invoice above a threshold amount triggers an SMS to the accounts payable manager; a purchase order pending approval triggers a voice call to the procurement director; a payment cleared against an invoice sends a status update to the accounts payable team. Reference data such as approver phone numbers and thresholds are stored in CloudSuite custom fields or external mapping tables. No data flows back from Twilio to CloudSuite; Twilio is notification-only.

How ml-connector handles it

ml-connector stores CloudSuite OAuth credentials and extracts the base URL and tenant ID from the .ionapi file. It refreshes the bearer token proactively before expiry (configurable 1 to 24 hours) to avoid mid-flow 401 errors. Twilio credentials are stored as HTTP Basic Auth (Account SID and Auth Token), and signature validation on inbound webhooks uses HMAC-SHA1. Polling on the CloudSuite side reads invoices and purchase orders filtered by modified date or status, respecting the 100 to 500 requests-per-minute rate limit and backing off on 429 responses. Outbound messages to Twilio use the REST API to send SMS to phone numbers retrieved from CloudSuite or from a lookup table, with retry logic for transient failures. Because Twilio webhooks are not guaranteed exactly-once, ml-connector deduplicates by message SID on inbound status callbacks. Every transaction is logged with full context (invoice ID, PO number, recipient phone number, message SID) for audit and replay.

A real-world example

A mid-market manufacturer with multiple plants uses Infor CloudSuite M3 for procurement and accounts payable. Invoices from key suppliers (materials, components, logistics) arrive throughout the day, and approval workflows depend on invoice amount and supplier criticality. Before the integration, the AP team had to log into CloudSuite multiple times daily to check for new invoices; high-value invoices were missed if the team was in meetings. With Twilio connected, CloudSuite now sends an SMS alert to the appropriate approver the moment a new invoice is received, with the vendor name and amount in the message. The approver can open CloudSuite from the alert if approval is needed, and the team never misses a time-sensitive invoice again.

What you can do

• •Route new supplier invoices from Infor CloudSuite to SMS alerts on Twilio, with thresholds based on invoice amount or supplier category.
• •Send voice call notifications to procurement approvers when a purchase order requires sign-off, with order number and status in the call transcript.
• •Update the AP team via SMS when a payment clears against an invoice in CloudSuite, for same-day reconciliation visibility.
• •Authenticate CloudSuite with OAuth 2.0 Resource Owner Password Credentials via the ION API Gateway, and Twilio with HTTP Basic Auth, with proactive token refresh.
• •Poll CloudSuite invoices and POs on your schedule, validate Twilio webhook signatures, deduplicate inbound status callbacks, and log every notification with full audit trail.

Questions

Can alerts flow from Twilio back into CloudSuite?

No. This integration is notification-only: CloudSuite is the source of invoice and PO events, and Twilio is the outbound channel for SMS and voice alerts. Inbound messages or call events from Twilio are not written back to CloudSuite. If you need to log call recordings or inbound SMS back to CloudSuite, that would require a separate flow using a different connector.

How does ml-connector handle CloudSuite's per-customer base URL and OAuth endpoint?

The .ionapi credentials file includes the base URL and tenant ID specific to your CloudSuite instance, and ml-connector extracts those values during setup. The OAuth token endpoint is also constructed from fields in the .ionapi file, so multi-tenant deployments across regions are supported without hardcoding endpoints. Token lifetime is configurable per tenant, so ml-connector proactively refreshes before expiry to avoid outages.

What happens if a Twilio message delivery fails?

ml-connector retries transient failures (network errors, Twilio 5xx responses) with exponential backoff. If a delivery ultimately fails (e.g., invalid phone number, carrier rejection), the alert is logged with the failure reason so your team can investigate and requeue manually. Inbound webhook callbacks from Twilio are deduplicated by message SID to prevent duplicate delivery notifications.
