title: Import & Export
---
_since v3.3.0_
Unleash supports import and export of feature-toggles and strategies at startup and during runtime. The import mechanism will guarantee that all imported features will be non-archived, as well as updates to strategies and features are included in the event history.
All import mechanisms support a `drop` parameter which will clean the database before import (all strategies and features will be removed).
> You should be careful when using `drop` parameter in production environments, as it will clean current state.
## Runtime import & export
### State Service
Unleash returns a StateService when started, you can use this to import and export data at any time.
```javascript
const unleash = require('unleash-server');
const { services } = await unleash.start({...});
const { stateService } = services;
const exportedData = await stateService.export({includeStrategies: false, includeFeatureToggles: true, includeTags: true, includeProjects: true});
await stateService.import({data: exportedData, userName: 'import', dropBeforeImport: false});
await stateService.importFile({file: 'exported-data.yml', userName: 'import', dropBeforeImport: true})
```
If you want the database to be cleaned before import (all strategies and features will be removed), set the `dropBeforeImport` parameter.
It is also possible to not override exiting feature toggles (and strategies) by using the `keepExisting` parameter.
### API Export
The api endpoint `/api/admin/state/export` will export feature-toggles and strategies as json by default.\
You can customize the export with query parameters:
| Parameter | Default | Description |
| --- | --- | --- |
| format | `json` | Export format, either `json` or `yaml` |
| download | `false` | If the exported data should be downloaded as a file |
| featureToggles | `true` | Include feature-toggles in the exported data |
| strategies | `true` | Include strategies in the exported data |
| tags | `true` | Include tagtypes, tags and feature_tags in the exported data |
| projects | `true` | Include projects in the exported data |
For example if you want to download just feature-toggles as yaml:
```
/api/admin/state/export?format=yaml&featureToggles=1&strategies=0&tags=0&projects=0&download=1
```
Example with curl:
```sh
curl -X GET -H "Content-Type: application/json" \
-H "Authorization: Basic YWRtaW46" \
http://unleash.herokuapp.com/api/admin/state/export?&featureToggles=1&strategies=0 > export.json
```
### API Import
You can import feature-toggles and strategies by POSTing to the `/api/admin/state/import` endpoint (keep in mind this will require authentication).\
You can either send the data as JSON in the POST-body or send a `file` parameter with `multipart/form-data` (YAML files are also accepted here).
If you want the database to be cleaned before import (all strategies and features will be removed), specify a `drop` query parameter.
> You should never use this in production environments.
Example usage:
```
POST /api/admin/state/import
{
"features": [
{
"name": "a-feature-toggle",
"enabled": true,
"description": "#1 feature-toggle"
}
]
}
```
Example with curl:
```sh
curl -X POST -H "Content-Type: application/json" \
-H "Authorization: Basic YWRtaW46" -d @export.json \
http://localhost:4242/api/admin/state/import
```
\*) Remember to set correct token for Authorization.
## Startup import
### Import files via config parameter
You can import a json or yaml file via the configuration option `importFile`.
Example usage: `unleash-server --databaseUrl ... --importFile export.yml`.
If you want the database to be cleaned before import (all strategies and features will be removed), specify the `dropBeforeImport` option.
> You should never use this in production environments.
Example usage: `unleash-server --databaseUrl ... --importFile export.yml --dropBeforeImport`.
These options can also be passed into the `unleash.start()` entrypoint.
