Connect Coupa to Parabola

Pull Coupa invoices and purchase orders into Parabola to automate three-way match reconciliations, supplier reporting, and spend dashboards.

Coupa is a cloud-based business spend management platform that helps organizations control procurement, invoicing, expenses, and supplier relationships in one system. Used by finance, procurement, and AP teams, Coupa automates purchasing workflows, processes invoices, and gives real-time visibility into organizational spend. Connecting Coupa to Parabola lets ops teams automate reconciliations, build custom dashboards, and combine procurement data with other systems, eliminating the manual CSV exports and spreadsheet work that slow down month-end close and strategic decision-making.

Pull from Coupa

The Pull from Coupa step brings invoices and purchase orders directly into a flow for real-time spend analysis and cross-system reconciliations. Use it to retrieve invoice and PO data on a schedule, combine Coupa data with ERP, warehouse, and sales channel information, track procurement performance, and build automated dashboards showing spend by supplier, status, and time period.

How to authenticate

Coupa uses OAuth 2.0 Client Credentials. To connect Coupa to Parabola, create an OAuth client in your Coupa instance and obtain your credentials.

Creating an OAuth client in Coupa

1. Log in to your Coupa instance as an administrator with integration permissions.

2. Navigate to Setup > Oauth2/OpenID Connect Clients. You can type “oauth” in the search box to find it quickly.

3. Click Create.

4. From the Grant Type dropdown, select Client credentials.

5. Fill in the required fields:

   • Name: give your client a descriptive name (for example, “Parabola Integration”)
   • Login: your admin username
   • Contact First Name, Contact Last Name, and Contact Email: your contact information
6. Select the Scopes you need:

   • core.accounting.read — required to access invoices
   • core.purchase_order.read — required to access purchase orders
   • Add additional scopes based on your specific needs
7. Click Save.

8. After saving, you’ll see your Client ID (Identifier) and Client Secret. Copy these to a secure location, you’ll need them to connect in Parabola.

Connecting in Parabola

1. In your Parabola flow, add a Pull from Coupa step.

2. Click Authorize and enter:

   • Client ID: your Coupa OAuth client identifier
   • Client Secret: your Coupa OAuth client secret
   • Instance: your Coupa subdomain (for example, if your Coupa URL is https://acme.coupahost.com, enter acme)
   • Scopes: the scopes you selected when creating the client (for example, core.accounting.read core.purchase_order.read), separated by spaces
3. Click Connect. Parabola will securely store your credentials and handle token generation and refresh.

4. Once authenticated, select the data you want to pull and configure any filters.

Available data

Using the Pull from Coupa step, you can access:

• Invoices: invoice records including invoice numbers, status (draft, pending approval, approved, paid, voided, disputed), creation and update timestamps, totals, and file URLs for invoice PDFs. Filter by date ranges, status, or account type.
• Invoice details by ID: full details for a specific invoice using its unique identifier.
• Purchase orders: PO records including PO numbers, status (draft, pending approval, approved, issued, closed, canceled), creation and update timestamps, order totals, and export status. Filter by date ranges, status, export status, or account type.

All data can be filtered by creation date, update date, status, and account type. The integration supports pagination to handle large datasets efficiently.

Common use cases

• Three-way match reconciliation: Pull invoices and POs from Coupa, combine with receiving data from your warehouse or ERP, and flag discrepancies in quantities, pricing, or missing documents. Push the result into NetSuite, QuickBooks Online, or Microsoft Dynamics Finance.
• Spend analysis and reporting: Aggregate invoice data by supplier, category, or time period to create dashboards showing spending trends, budget utilization, and savings opportunities. Push results to Google Drive, Smartsheet, Looker, or Metabase.
• Invoice processing automation: Monitor pending and approved invoices, combine with payment data from Ramp or your accounting system, and track time-to-payment or invoices stuck in approval.
• Purchase order tracking: Track PO status from creation through closure, identify open POs aging beyond expected timelines, and alert procurement teams in Slack about delayed orders or missing receipts.
• Supplier performance monitoring: Combine invoice and PO data with shipment records from FedEx, UPS, or DHL to calculate on-time delivery rates and identify suppliers with frequent disputes.
• Month-end close acceleration: Automate the extraction and reconciliation of invoices and POs against your GL or ERP system to reduce manual effort during financial close.

Tips for using Parabola with Coupa

• Match scopes on both sides. The scopes selected in Parabola must be enabled in your Coupa OAuth client. If a scope is missing on the Coupa side, the related data type will fail.
• Schedule around close. Daily or hourly runs during month-end close keep procurement data current and reduce last-minute reconciliation work.
• Use date filters strategically. Filter by created-at or updated-at to pull only recent records, which speeds up flows and reduces API load. For ongoing reconciliations, pull data from the last 30 to 90 days.
• Ask for just the fields you need. Use the fields setting to pull only the columns the flow uses. The fewer fields you request, the faster the data comes back from Coupa.
• Add validation checks. Use Filter and Formula steps to flag invoices without matching POs, POs in “issued” status for more than 60 days, or invoices in disputed status.
• Combine with other systems. Join Coupa data with NetSuite, QuickBooks Online, or warehouse data to catch cross-system discrepancies.

FAQ

Can I push data back into Coupa?

The Pull from Coupa step is read-only. To create or update Coupa records (for example, posting an invoice), use a Send to an API step pointed at the relevant Coupa endpoint with your OAuth credentials.

Why is my connection failing for one data type but working for others?

The scope for that data type isn’t enabled in your Coupa OAuth client. Open Setup > Oauth2/OpenID Connect Clients in Coupa, edit your client, add the missing scope, and reconnect in Parabola.

How do I find my Coupa instance value?

It’s the subdomain in your Coupa URL. If you log in at https://acme.coupahost.com, your instance value is acme.

Does the integration support Coupa’s Sourcing or Contracts modules?

The native step covers invoices and purchase orders. If your process requires sourcing events, contracts, or other Coupa modules, reach out to [e-mail].
