## Authentication

Every request requires two headers:

| ----------- | ------------------------------ |
| `X-API-KEY` | Your organization's API key    |
| `X-ORG-ID`  | Your organization's identifier |

```bash theme={null}
curl -X POST https://integration.fieldiu.online/api/v1/accounts \
  -H "X-API-KEY: your_api_key" \
  -H "X-ORG-ID: your_org_id" \
  -H "Content-Type: application/json"
```

<Note>
  Contact your FieldIU administrator to obtain your `X-API-KEY` and `X-ORG-ID` credentials.
