Step By Step
Assume that you want to check whether user anne
has relationship reader
with object document:Z
01. Configure the Okta FGA API Client
Before calling the check API, you will need to configure the API client.
- Node.js
- Go
- .NET
- Python
- Java
- CLI
- curl
const { CredentialsMethod, OpenFgaClient } = require('@openfga/sdk'); // OR import { CredentialsMethod, OpenFgaClient } from '@openfga/sdk';
// Ensure the environment variables are set
// FGA_API_URL = 'https://api.us1.fga.dev' // 'https://api.eu1.fga.dev' for EU and 'https://api.au1.fga.dev' for AU
// FGA_STORE_ID = 'YOUR_STORE_ID' - Get this from your store settings in the dashboard, refer to the "How to get your API Keys" page
// FGA_MODEL_ID = 'YOUR_MODEL_ID' - optional, can be overridden per request, helps reduce latency
// FGA_API_TOKEN_ISSUER = 'fga.us.auth0.com'

const fgaClient = new OpenFgaClient({

02. Calling Check API
To check whether user user:anne
has relationship reader
with object document:Z
- Node.js
- Go
- .NET
- Python
- Java
- CLI
- curl
// Run a check
const { allowed } = await fgaClient.check({
user: 'user:anne',
relation: 'reader',
object: 'document:Z',
}, {
authorization_model_id: '01HVMMBCMGZNT3SED4Z17ECXCA',
});
// allowed = true
options := ClientCheckOptions{
AuthorizationModelId: PtrString("01HVMMBCMGZNT3SED4Z17ECXCA"),
}
body := ClientCheckRequest{
User: "user:anne",
Relation: "reader",
Object: "document:Z",
}
data, err := fgaClient.Check(context.Background()).
Body(body).
Options(options).
Execute()
// data = { allowed: true }
var options = new ClientCheckOptions {
AuthorizationModelId = "01HVMMBCMGZNT3SED4Z17ECXCA",
};
var body = new ClientCheckRequest {
User = "user:anne",
Relation = "reader",
Object = "document:Z",
};
var response = await fgaClient.Check(body, options);
// response.Allowed = true
options = {
"authorization_model_id": "01HVMMBCMGZNT3SED4Z17ECXCA"
}
body = ClientCheckRequest(
user="user:anne",
relation="reader",
object="document:Z",
)
response = await fga_client.check(body, options)
# response.allowed = true
var options = new ClientCheckOptions()
.authorizationModelId("01HVMMBCMGZNT3SED4Z17ECXCA");
var body = new ClientCheckRequest()
.user("user:anne")
.relation("reader")
._object("document:Z");
var response = fgaClient.check(body, options).get();
// response.getAllowed() = true
fga query check --store-id=$FGA_STORE_ID --model-id=01HVMMBCMGZNT3SED4Z17ECXCA user:anne reader document:Z
# Response: {"allowed":true}
curl -X POST $FGA_API_URL/stores/$FGA_STORE_ID/check \
-H "Authorization: Bearer $FGA_API_TOKEN" \ # Not needed if service does not require authorization
-H "content-type: application/json" \
-d '{"authorization_model_id": "01HVMMBCMGZNT3SED4Z17ECXCA", "tuple_key":{"user":"user:anne","relation":"reader","object":"document:Z"}}'
# Response: {"allowed":true}
The result's allowed
field will return true
if the relationship exists and false
if the relationship does not exist.
