If the below command returns missing_text_or_fallback_or_attachments, it means that the URL is valid, any other responses would mean that the URL is invalid.
curl -s -X POST -H "Content-type: application/json" -d '{"text":""}' "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"
curl -sX POST "https://slack.com/api/auth.test?token=xoxp-TOKEN_HERE&pretty=1"
curl -u USERNAME:ACCESS_KEY https://saucelabs.com/rest/v1/users/USERNAME
You can generate access tokens by visiting the URL below.
https://graph.facebook.com/oauth/access_token?client_id=ID_HERE&client_secret=SECRET_HERE&redirect_uri=&grant_type=client_credentials

SSH private keys can be tested against github.com to see if they are registered against an existing user account. If the key exists the username corresponding to the key will be provided. (source)
$ ssh -i <path to SSH private key> -T git@github.com

Add the new access_key_id and secret within ~/.aws/credentials file as a new user (https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html).

The following powershell can be used to test a Shared Access Signature Token:
static void UseAccountSAS(string sasToken)
{
// Create new storage credentials using the SAS token.
StorageCredentials accountSAS = new StorageCredentials(sasToken);
// Use these credentials and the account name to create a Blob service client.
CloudStorageAccount accountWithSAS = new CloudStorageAccount(accountSAS, "account-name", endpointSuffix: null, useHttps: true);
CloudBlobClient blobClientWithSAS = accountWithSAS.CreateCloudBlobClient();
// Now set the service properties for the Blob client created with the SAS.
blobClientWithSAS.SetServiceProperties(new ServiceProperties()
{
HourMetrics = new MetricsProperties()
{
MetricsLevel = MetricsLevel.ServiceAndApi,
RetentionDays = 7,
Version = "1.0"
},
MinuteMetrics = new MetricsProperties()
{
MetricsLevel = MetricsLevel.ServiceAndApi,
RetentionDays = 7,
Version = "1.0"
},
Logging = new LoggingProperties()
{
LoggingOperations = LoggingOperations.All,
RetentionDays = 14,
Version = "1.0"
}
});
// The permissions granted by the account SAS also permit you to retrieve service properties.
ServiceProperties serviceProperties = blobClientWithSAS.GetServiceProperties();
Console.WriteLine(serviceProperties.HourMetrics.MetricsLevel);
Console.WriteLine(serviceProperties.HourMetrics.RetentionDays);
Console.WriteLine(serviceProperties.HourMetrics.Version);

Be cautious when running this command, since the payload might execute within an administrative environment, depending on what index you are editing the highlightPreTag of. It's recommended to use a more silent payload (such as XSS Hunter) to prove the possible cross-site scripting attack.
