  • 03Other Coupa operations use the Coupa API in the same workflow.

Workflow

How it fits into a Nexus workflow

TriggerIntegration: CoupaRules + CodeSovereign AI (optional)Human ApprovalSystem Action: CoupaAudit

Coupa steps run as pre-built actions. A run that uses them starts from a webhook, a schedule, a request in Nexus or another system's trigger source.

A trigger source starts work. A connector action performs work. Both run inside the same governed execution.

Beyond pre-built actions

When the pre-built action is not enough

Move down one step: an API, protocol or database call, then custom logic in Python, Bash, Go, Java, .NET, PHP, PowerShell or JavaScript/TypeScript with any library. Every step uses the same secrets, approvals, history and audit.

Pre-built ActionAPI / Protocol / DBRules + CodeApprovalAudit

01

Call the Coupa API with the HTTP Request node, or use GraphQL, SOAP or a database node where the system exposes one.

02

Write custom integration logic in Python, Bash, Go, Java, .NET, PHP, PowerShell or JavaScript/TypeScript, with the libraries your team already uses.

03

Direct calls and code use the same vault-backed secrets, approvals, run history and audit as pre-built actions.

Examples

Workflow examples

Invoice intake to Coupa

An invoice file is read and validated, then created in Coupa with its lines.

Tolerance check before creation

Invoices outside tolerance pause for a procurement owner.

ERP cross-check

Invoice data is compared with SAP purchase records before the Coupa write.

Deployment, trust and audit

Governance, audit and deployment

Deployment

Nexus runs on-premises, in private or sovereign cloud, or air-gapped. The step needs network reach to the system it calls, and nothing else changes.

Secrets and identity

Credentials are referenced through vault-backed secret handling and role-based access, never embedded in workflow logic.

Audit

Inputs, outputs, approvals and outcomes are written to the execution history for every run.

Multi-system workflows

Use cases that include Coupa

AWS S3 or Azure Blob Storage, SAP, MSSQL or Oracle

Invoice intake and reconciliation with object storage, SAP and SQL

A file lands in object storage, SAP and a reconciliation database are checked, Rules + Code matches the result and exceptions go to a named reviewer.

Industry use cases

Processes that use Coupa

Financial services

Invoice approval and procurement

Invoices are checked against procurement records and approved before they are created.

Enterprise

Procure-to-pay exception workflow

Invoice, procurement and payment exceptions are resolved with approval across four systems.
