### Get Procedure Details via SDKs

Source: https://graphscope.io/docs/flex/interactive/development/restful_api

Examples for retrieving specific procedure details using PHP, Perl, Python, and Rust SDKs.

```php
<?php
// Create an instance of the API class
$api_instance = new OpenAPITools\Client\Api\AdminServiceProcedureManagementApi();
$graphId = graphId_example; // String | 
$procedureId = procedureId_example; // String | 

try {
    $result = $api_instance->getProcedure($graphId, $procedureId);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling AdminServiceProcedureManagementApi->getProcedure: ', $e->getMessage(), PHP_EOL;
}
?>
```

```perl
use Data::Dumper;
use WWW::OPenAPIClient::Configuration;
use WWW::OPenAPIClient::AdminServiceProcedureManagementApi;

# Create an instance of the API class
my $api_instance = WWW::OPenAPIClient::AdminServiceProcedureManagementApi->new();
my $graphId = graphId_example; # String | 
my $procedureId = procedureId_example; # String | 

eval {
    my $result = $api_instance->getProcedure(graphId => $graphId, procedureId => $procedureId);
    print Dumper($result);
};
if ($@) {
    warn "Exception when calling AdminServiceProcedureManagementApi->getProcedure: $@\n";
}
```

```python
from __future__ import print_statement
import time
import openapi_client
from openapi_client.rest import ApiException
from pprint import pprint

# Create an instance of the API class
api_instance = openapi_client.AdminServiceProcedureManagementApi()
graphId = graphId_example # String |  (default to null)
procedureId = procedureId_example # String |  (default to null)

try:
    api_response = api_instance.get_procedure(graphId, procedureId)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling AdminServiceProcedureManagementApi->getProcedure: %s\n" % e)
```

```rust
extern crate AdminServiceProcedureManagementApi;

pub fn main() {
    let graphId = graphId_example; // String
    let procedureId = procedureId_example; // String

    let mut context = AdminServiceProcedureManagementApi::Context::default();
    let result = client.getProcedure(graphId, procedureId, &context).wait();

    println!("{:?}", result);
}
```
