Workflow

## Move from documented endpoint to operational data flow.

API access gives technical teams a clear path to evaluate endpoints, validate permissions, and connect GreenPowerHub data where daily work already happens.

1

### Choose the API area

Start with the data or workflow your team needs, such as closing prices, product IDs, interests, trades, or partners.

2

### Review the contract

Use the developer portal to inspect endpoints, request parameters, headers, response schemas, and OpenAPI definitions.

3

### Validate in sandbox

Use test access to confirm authentication, data shape, rate expectations, and operational ownership before production.

4

### Move to production

Move live once access, subscription, keys, and the integration workflow are aligned.

**Real developer surface** The developer portal shows the API catalogue, selected API version, operation list, request URL, and parameter table.

**Prices API v2** Closing prices are a clear starting point for teams that want market data in internal dashboards, models, and reporting.

**Controlled access** Keys, roles, and subscriptions remain controlled while public documentation helps teams plan the integration path.

Use cases

## Where API access fits

Operations teams

### Partner and trade records

Why it matters

## API access turns market data into a repeatable operational input.

When pricing and workflow data can move into internal systems, teams can reduce manual exports and make GreenPowerHub context part of recurring analysis.
