Coupa

Coupa is a business spend management (BSM) platform. This piece automates procurement, approvals, purchase orders, and ERP integrations through the Coupa Core API.

Authentication

Connect using an OAuth 2.0 / OpenID Connect client with the Client Credentials grant. In Coupa, go to Setup → Integrations → OAuth2/OpenID Connect Clients, create a client, and copy the Client ID and Client Secret. Provide the space-separated scopes your client was granted (e.g. core.purchase_order.read core.purchase_order.write).

Actions

• Create / Update / Get / Search Object — generic CRUD against Purchase Orders, Suppliers, Contracts, or any custom resource.
• Cancel / Close Purchase Order — manage the purchase order lifecycle.
• Grant / Reject Approval — act on pending approvals.
• Add File Attachment to Object — attach a file or a URL to a record.
• Get Remit-To Addresses — list remit-to addresses for a supplier or a purchase order's supplier.
• Get Supplier Sites — list a supplier's sites.
• Set Integration Run Status — update an integration run (run, success, fail, pause, pending).
• Custom API Call — call any Coupa Core API endpoint directly.

Triggers

• New or Updated Object — polls for created or updated Purchase Orders, Suppliers, or Contracts.
