'
```

### Python

```python
import requests

url = "https://api.m3ter.com/organizations/{orgId}/compoundaggregations"

payload = {
    "name": "<string>",
    "quantityPerUnit": 1,
    "unit": "<string>",
    "calculation": "<string>",
    "version": 123,
    "customFields": {},

  method: 'POST',
  headers: {Authorization: 'Bearer <token>', 'Content-Type': 'application/json'},
  body: JSON.stringify({
    name: '<string>',
    quantityPerUnit: 1,
    unit: '<string>',
    calculation: '<string>',
    version: 123,
    customFields: {},
    code: 'example_code',
    accountingProductId: '<string>',
    productId: '<string>',
    evaluateNullAggregations: true
  })
};

fetch('https://api.m3ter.com/organizations/{orgId}/compoundaggregations', options)
  .then(res => res.json())
  .then(res => console.log(res))
  .catch(err => console.error(err));
```
