Example

curl {HOST}/api/admin/login_check
    -H 'Content-Type: application/json;charset=UTF-8'
    -H 'Accept: application/json, text/plain, */*'

    "token":"eyJhbGciOiJSUzI1NiIsInR5cCI6...",
    "refresh_token":"0558f8bb29948c4e54c443f..."
}

Using JSON Web Token

Add authorization header to each request
Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6...
You can now access any API method you want under the /api prefix.

Example

curl {HOST}/api/{storeCode}/analytics/members
    -H 'Accept: application/json'
    -H 'Content-type: application/x-www-form-urlencoded'
    -H 'Authorization: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6...'

Refresh JSON Web Token

You can refresh token using refresh_token that was given during login.
