How does ml-connector handle Oracle JD Edwards session token expiry?

Oracle JD Edwards session tokens expire every 30 to 60 minutes by default. ml-connector obtains a fresh token at the start of each sync cycle and immediately re-authenticates if a request returns HTTP 444 (invalid token). The AIS Server URL, username, and password are stored encrypted so re-authentication is automatic.

Can ml-connector use webhooks from Ramp instead of polling Oracle JD Edwards?

Yes. Ramp supports real-time webhooks for bills, transactions, and vendors, verified via HMAC-SHA256 signature. ml-connector can subscribe to Ramp webhooks so bills are posted into Oracle JD Edwards as soon as they are created or updated in Ramp, rather than waiting for a scheduled poll cycle.

Oracle JD Edwards and Ramp integration

Oracle JD Edwards handles your general ledger and accounts payable. Ramp handles your corporate spend across cards, bills, and expenses. Connecting the two keeps your supplier master and GL accounts in agreement, and moves bills from Ramp into Oracle JD Edwards as AP vouchers without manual re-keying. ml-connector handles the very different APIs on each side and moves the data on a schedule you control.

How Oracle JD Edwards works

Oracle JD Edwards EnterpriseOne runs at customer infrastructure via an Application Interface Services (AIS) Server, exposed through REST APIs at a customer-provided hostname and port. It authenticates with a session token obtained via POST to /jderest/v2/tokenrequest with username and password, returned as an opaque token passed in the jde-AIS-Auth header on all subsequent requests. Alternatively, HTTP Basic Auth can be used per-request. Session tokens expire every 30 to 60 minutes by default and must be refreshed. Oracle JD Edwards has no native outbound webhooks, so data is read by polling on a schedule, with pagination via maxPageSize parameter and moreRecords flag.

How Ramp works

Ramp exposes transactions, vendors, bills, purchase orders, GL accounts, and users through a REST API at https://api.ramp.com/developer/v1. It authenticates with OAuth 2.0 Client Credentials flow, where a client_id and client_secret are exchanged for a bearer token valid 10 days. Ramp supports real-time webhooks via HMAC-SHA256 signature verification for bills, transactions, vendors, and other events, but also allows polling for compatibility with on-premises backends. Sensitive data such as card vault information requires additional scopes.

What moves between them

The main flow runs from Ramp into Oracle JD Edwards. Bills created or updated in Ramp are read via REST API or pushed via webhook, then posted into Oracle JD Edwards as F0411Z1 (Batch Voucher Entry) records tied to the matching supplier in the F0101 (Address Book). Vendors from Ramp are synced into Oracle JD Edwards as F0401 (Supplier Master) records. Purchase orders from Ramp can be read and matched to Oracle JD Edwards F4301 (Purchase Order Header) records for GL account mapping. GL postings flow one direction only, since Ramp is a spend platform without a two-way GL sync model.

How ml-connector handles it

ml-connector stores the AIS Server URL, username, and password encrypted, and obtains a session token at the start of each sync cycle, refreshing when HTTP 444 is returned. On the Ramp side, it stores the OAuth client_id and client_secret encrypted, obtains a bearer token that lasts 10 days, and uses either polling or webhook subscription depending on customer preference. Bills and vendors are mapped to Oracle JD Edwards supplier records by Ramp vendor_id; if a new vendor appears in Ramp, ml-connector creates a skeleton F0101 Address Book record so the bill can post. GL account codes are validated against the F0901 (Account Master) before posting. Because Oracle JD Edwards is pull-only and operates with fixed rate limits per AIS Server instance, ml-connector polls on a schedule you define rather than pushing in real time. Every record carries a full audit trail and can be replayed if a downstream post fails.

A real-world example

A mid-sized professional services firm runs Oracle JD Edwards on-premises for accounting and procurement, and uses Ramp for corporate spend across employee cards, vendor bills, and travel. Before the integration, the accounting team exported bills from Ramp every week and re-entered them into Oracle JD Edwards as AP vouchers by hand, then manually reconciled the vendor master when new Ramp vendors appeared. With Oracle JD Edwards and Ramp connected, each new bill flows automatically into the AP ledger under the matching vendor, and new vendors are provisioned in the supplier master without manual intervention. Month-end closes are faster because AP aging reports now reflect the true state of bills paid via Ramp.

What you can do

Read bills, vendors, and purchase orders from Ramp via REST API or webhook, and post them into Oracle JD Edwards as AP vouchers and supplier master records.
Keep Oracle JD Edwards vendor master (F0401) synchronized with Ramp vendors so new suppliers do not block bill posting.
Validate GL account codes against Oracle JD Edwards Account Master (F0901) before posting bills so AP transactions land on correct accounts.
Handle AIS Server session token refresh on expiry (30-60 minute windows) and OAuth token lifecycle on the Ramp side (10 days per Client Credentials flow).
Poll on a schedule tied to your bill cycle, with full audit trail, error replay, and support for both polling and webhook-driven sync from Ramp.
