By default each scope grants **read** permissions to the described resource.\
You may request **write** (granting you read, create and edit permissions on the resource) as well as **delete** permissions (granting you read, create, edit and delete permissions on the resource).

**Examples**:

<table data-header-hidden><thead><tr><th></th><th></th><th data-hidden></th></tr></thead><tbody><tr><td>service</td><td>grants GET on /api/services</td><td></td></tr><tr><td>service:r</td><td>same as service</td><td></td></tr><tr><td>service:w</td><td>grants GET, POST, PUT on /api/services</td><td></td></tr><tr><td>service:d</td><td>grants GET, POST, PUT, DELETE on /api/services</td><td></td></tr></tbody></table>

You may request multiple scopes by separating them with a space.

**Like so**: `profile service:w offline_access`

{% hint style="info" %}
If you are building a backend application and it is verified, your refresh\_token lifetime may be changed so that they never expire. Please [reach out to us](https://github.com/iLert/docs/blob/master/developer-docs/contact.md).
{% endhint %}

## App verification

{% hint style="success" %}
We would love to hear about and verify your applications, feel free to [reach out to us](https://github.com/iLert/docs/blob/master/developer-docs/contact.md), as soon as you are ready.
{% endhint %}

## Other info

{% hint style="warning" %}
Do not rely on a users email address without being sure it is verified, or your application might be open to attacks where the email address is mimiced on the authorization server.

Use the username or the user's id to verify account ownership in your app.
