Detailed Information

Slack Webhook

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.

Microsoft Shared Access Signatures (SAS)

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);
}

Microsoft Teams Webhook

If the below command returns Summary or Text is required., it means that the URL is valid. If it returns Invalid webhook URL or any other responses would mean that the URL is invalid.

curl -H "Content-Type:application/json" -d "{'text':''}" "YOUR_WEBHOOK_URL"

New Relic Personal API Key (NerdGraph)

curl -X POST https://api.newrelic.com/graphql \
-H 'Content-Type: application/json' \
-H 'API-Key: YOUR_API_KEY' \
-d '{ "query":  "{ requestContext { userId apiKey } }" } '

New Relic REST API

curl -X GET 'https://api.newrelic.com/v2/applications.json' \
     -H "X-Api-Key:${APIKEY}" -i

If valid, test further to see if it's an admin key

Heroku API key

curl -X POST https://api.heroku.com/apps -H "Accept: application/vnd.heroku+json; version=3" -H "Authorization: Bearer API_KEY_HERE"

Mapbox API key

Mapbox secret keys start with sk, rest start with pk (public token), sk (secret token), or tk (temporary token).

curl "https://api.mapbox.com/geocoding/v5/mapbox.places/Los%20Angeles.json?access_token=ACCESS_TOKEN"

#Check token validity
curl "https://api.mapbox.com/tokens/v2?access_token=YOUR_MAPBOX_ACCESS_TOKEN"

#Get list of all tokens associated with an account. (only works if the token is a Secret Token (sk), and has the appropiate scope)
curl "https://api.mapbox.com/tokens/v2/MAPBOX_USERNAME_HERE?access_token=YOUR_MAPBOX_ACCESS_TOKEN"

Salesforce API key

curl https://instance_name.salesforce.com/services/data/v20.0/ -H 'Authorization: Bearer access_token_here'

Algolia API key

If the key has the listIndexes permission, you can list indexes with:

curl --request GET \
  --url https://<example-app-id>-1.algolianet.com/1/indexes/ \
  --header 'content-type: application/json' \
  --header 'x-algolia-api-key: <example-key>' \
  --header 'x-algolia-application-id: <example-appid>'

Otherwise you will have to know the name of an index (check the app source code or the requests it does). Then to enumerate its content:

curl --request GET \
  --url https://<example-app-id>-1.algolianet.com/1/indexes/<example-index> \
  --header 'content-type: application/json' \
  --header 'x-algolia-api-key: <example-key>' \
  --header 'x-algolia-application-id: <example-appid>'

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.

curl --request PUT \
  --url https://<application-id>-1.algolianet.com/1/indexes/<example-index>/settings \
  --header 'content-type: application/json' \
  --header 'x-algolia-api-key: <example-key>' \
  --header 'x-algolia-application-id: <example-application-id>' \
  --data '{"highlightPreTag": "<script>alert(1);</script>"}'

Zapier Webhook Token

Google Recaptcha key

Send a POST to the following URL:

https://www.google.com/recaptcha/api/siteverify

secret and response are two required POST parameters, where secret is the key and response is the response to test for.

Regular expression: ^6[0-9a-zA-Z_-]{39}$. The API key always starts with a 6 and is 40 chars long. Read more here: https://developers.google.com/recaptcha/docs/verify.

Google Cloud Service Account credentials

Service Account credentials may be found in a JSON file like this:

$ cat service_account.json
{
  "type": "service_account",
  "project_id": "...",
  "private_key_id": "...",
  "private_key": "-----BEGIN PRIVATE KEY-----...-----END PRIVATE KEY-----\n",
  "client_email": "...",
  "client_id": "...",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://oauth2.googleapis.com/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/..."
}

If this is your case you may check these credentials using gcloud tool (how to install gcloud):

$ gcloud auth activate-service-account --key-file=service_account.json
Activated service account credentials for: [...]
$ gcloud auth print-access-token
ya29.c...

In case of success you'll see access token printed in terminal. Please note that after verifying that credentials are actually valid you may want to enumerate permissions of these credentials which is another story.

Paypal client id and secret key

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
   -H "Accept: application/json" \
   -H "Accept-Language: en_US" \
   -u "client_id:secret" \
   -d "grant_type=client_credentials"

The access token can be further used to extract data from the PayPal API. More information: https://developer.paypal.com/docs/api/overview/#make-rest-api-calls.

This can be verified using:

curl -v -X GET "https://api.sandbox.paypal.com/v1/identity/oauth2/userinfo?schema=paypalv1.1" -H "Content-Type: application/json" -H "Authorization: Bearer [ACCESS_TOKEN]"

Stripe Live Token

curl https://api.stripe.com/v1/charges -u token_here:

Keep the colon at the end of the token to prevent cURL from requesting a password.

The token is always in the following format: sk_live_24charshere, where the 24charshere part contains 24 characters from a-z A-Z 0-9. There is also a test key, which starts with sk_test, but this key is worthless since it is only used for testing purposes and most likely doesn't contain any sensitive information. The live key, on the other hand, can be used to extract/retrieve a lot of info — ranging from charges to the complete product list.

Keep in mind that you will never be able to get the full credit card information since Stripe only gives you the last 4 digits.

More info/complete documentation: https://stripe.com/docs/api/authentication.

Razorpay API key and Secret key

This can be verified using:

curl -u <YOUR_KEY_ID>:<YOUR_KEY_SECRET> \
  https://api.razorpay.com/v1/payments

  -H "Authorization: Bearer <YOUR_API_TOKEN>"

Loqate API key

curl 'http://api.addressy.com/Capture/Interactive/Find/v1.00/json3.ws?Key=<KEY_HERE>&Countries=US,CA&Language=en&Limit=5&Text=BHAR'

Ipstack API Key

curl 'https://api.ipstack.com/{ip_address}?access_key={keyhere}'

NPM token

You can verify NPM token using npm (replacing 00000000-0000-0000-0000-000000000000 with NPM token):

export NPM_TOKEN="00000000-0000-0000-0000-000000000000"
echo "//registry.npmjs.org/:_authToken=${NPM_TOKEN}" > .npmrc
npm whoami

Another way to verify token is to query API directly:

curl -H 'authorization: Bearer 00000000-0000-0000-0000-000000000000' 'https://registry.npmjs.org/-/whoami'

You'll get username in response in case of success, 401 Unauthorized in case if token doesn't exists and 403 Forbidden in case if your IP address is not whitelisted.

NPM token can be CIDR-whitelisted. Thus if you are using token from non-whitelisted CIDR you'll get 403 Forbidden in response. So try to verify NPM token from different IP ranges!.

P.S. Some companies uses registries other than registry.npmjs.org. If it's the case replace all registry.npmjs.org occurrences with domain name of company's NPM registry.

OpsGenie API Key

curl https://api.opsgenie.com/v2/alerts -H 'Authorization: GenieKey API_KEY'

Keen.io API Key

Get all collections for a specific project:

curl "https://api.keen.io/3.0/projects/PROJECT_ID/events?api_key=READ_KEY"

Note: Keep the colon at the end of the token to prevent cURL from requesting a password. Info: The token is always in the following format: sk_live_34charshere, where the 34charshere part contains 34 characters from a-z A-Z 0-9 There is also a test key, which starts with sk_test, but this key is worthless since it is only used for testing purposes and most likely doesn't contain any sensitive info.
