Who is this for?

Oracle Fusion integration developers

Building and maintaining integrations against HCM (Human Capital Management), FSCM (Financials and Supply Chain Management), and BPM (Business Process Management) REST APIs.

Oracle HCM, FSCM & BPM consultants

Exploring endpoints and building queries for client implementations.

HR IT teams

Building or maintaining integrations without dedicated API tooling.

Built around how Oracle Fusion developers actually work

From endpoint discovery to live request, without switching tools.

Find any endpoint instantly

59,000+ HCM, FSCM, and BPM endpoints indexed locally. Search by name, parameter, or description — results in under 200ms, no login, no internet.

Q Builder and Finder Builder

Build Oracle's q= filters visually — pick fields, operators, and values; OPAL generates the expression. Switch to the Finder Builder to target named lookups like PrimaryKey or findByPersonId without writing a single character.

Automate multi-step Oracle workflows

Chain API calls into flows — no scripting required. Connect once, then send authenticated requests, inspect responses, and export to cURL.

How it works

From download to your first Oracle API request in under 5 minutes.

1

Download and open

No account required. The app opens with 59,000+ endpoints already bundled and indexed.

2

Search your endpoint

Type any keyword — resource, parameter, or description. Results in under 200ms.

3

Build and send

Use the Q Builder or Finder Builder to construct your query visually — no syntax to memorize. Add headers, send to your Oracle instance, and inspect the response or chain into a flow.

Frequently asked questions

Does OPAL work with my Oracle Fusion version?

Works with any Oracle Fusion Cloud SaaS instance. No version requirement. Bundled specs cover HCM, FSCM, and BPM.

Is my Oracle credentials and data safe?

Credentials stored locally, encrypted AES-256-GCM. No cloud sync, no telemetry, no external server.

Is OPAL free?

Yes. Every feature is free: catalog, Q Builder, Finder Builder, schema viewer, live requests, flow runner, and export backup. No account, no license key.

Can I use OPAL without connecting to Oracle?

Yes. The bundled specs work entirely offline. Live Oracle instance only needed for live requests.
