Test Credentials

Twilio provides you with a set of test credentials so you can exercise parts of the REST API without charging your account. You can find your credentials in the Auth Tokens page of your Console.

You use these credentials in the same way as your live credentials, with one restriction being that you cannot log in to the Twilio CLI with your test credentials. However, when you authenticate with your test credentials, we will not charge your account, update the state of your account, or connect to real phone numbers. You can now pretend to buy a phone number or send an SMS, without actually doing so.

To protect your production data, your test credentials can't interact with the data in your real account. For example, you can't use phone numbers from your real account as the 'From' number in requests made with your test credentials.

Supported Resources

Your test credentials can currently be used to interact with the following three resources:

Buying phone numbers: POST /2010-04-01/Accounts/{TestAccountSid}/IncomingPhoneNumbers
Sending SMS messages: POST /2010-04-01/Accounts/{TestAccountSid}/Messages
Making calls: POST /2010-04-01/Accounts/{TestAccountSid}/Calls

Requests to any other resource with test credentials will receive a 403 Forbidden response. In the future, we may enable these resources for testing as well.

(warning)

Warning

A limitation of SMS messages and calls made using test credentials is that they will not trigger status callbacks. Learn more about status callbacks for outbound SMS and status callbacks for Voice.

Magic Input

When you make an API request with your test credentials, Twilio will validate all input as though the request were made with your real credentials. However, there are some cases when a request's validity depends on the state of Twilio. For instance, if you are trying to buy a phone number and that phone number is no longer available, Twilio will return an error.

To write test cases that expect and handle errors which depend on the state of Twilio, we provide magic inputs. For the case mentioned above, there is a magic phone number +15005550000 which if you pass it as the 'PhoneNumber' parameter in a POST to IncomingPhoneNumbers, will always return an error saying the number is unavailable.

The full set of magic inputs is detailed below.

Test Buying A Number

If you'd like to test API requests to the phone numbers resource without provisioning a number for your account, you can use your test credentials.

You use these credentials in the same way as your live credentials. However, when you authenticate with your test credentials, we will not charge your account or purchase a phone number for you. This way, you can pretend to buy a phone number without actually doing so.

Just POST to the normal phone number purchase API endpoint using your test credentials to authenticate and your TestAccountSid in the URL:

1POST https://api.twilio.com/2010-04-01/Accounts/{TestAccountSid}/IncomingPhoneNumbers
2

Parameters

All of the existing phone number purchase parameters will work. In addition, we provide some specific values for certain parameters to help you generate success and failure cases.

PhoneNumber

Value	Description	Error Code
+15005550000	This phone number is unavailable.	21422
+15005550001	This phone number is invalid.	21421
+15005550006	This phone number is valid and available.	No error

AreaCode

Value	Description	Error Code
533	This area code doesn't have any available phone numbers.	21452
500	This area code has an available number.	No error

Example 1

Successfully provision a number. Purchase will always be completed successfully if you attempt to purchase the magic number +15005550006. Any other parameters you send with the request, such as a VoiceUrl or a StatusCallback, will be included in the API response.

Test Sending an SMS

If you'd like to test API requests to send SMS messages without charging your account or sending an SMS, you can use your test credentials.

Just POST to the normal SMS API endpoint using your test credentials to authenticate and your TestAccountSid in the URL:

1POST https://api.twilio.com/2010-04-01/Accounts/{TestAccountSid}/Messages
2

Parameters

All of the existing outbound SMS parameters will work, except for MessagingServiceSid. In addition, we provide some specific values for certain parameters to help you generate success and failure cases.

From

Your test credentials don't have access to any valid 'From' phone numbers on your real account. Therefore, the only phone numbers you should use as 'From' numbers are the magic numbers listed here.

Value	Description	Error Code
+15005550001	This phone number is invalid.	21212
+15005550007	This phone number is not owned by your account or is not SMS-capable.	21606
+15005550008	This number has an SMS message queue that is full.	21611
+15005550006	This number passes all validation.	No error
All Others	This phone number is not owned by your account or is not SMS-capable.	21606

To

Value	Description	Error Code
+15005550001	This phone number is invalid.	21211
+15005550002	Twilio cannot route to this number.	21612
+15005550003	Your account doesn't have the international permissions necessary to SMS this number.	21408
+15005550004	This number is blocked for your account.	21610
+15005550009	This number is incapable of receiving SMS messages.	21614
All Others	Any other phone number is validated normally.	Input-dependent

Example 1

Successfully send an SMS. Trigger this by sending an SMS using the magic number +15005550006 as the From number, and a regular phone number for the To number.

Test Making a Call

If you'd like to test API requests to the outbound call endpoint without charging your account or making a call, you can use your test credentials. Note that since no call is made, Twilio will not request the URL passed in the 'Url' parameter and no TwiML will be executed.

Just POST to the normal outbound call API endpoint using your test credentials to authenticate and your TestAccountSid in the URL:

1POST https://api.twilio.com/2010-04-01/Accounts/{TestAccountSid}/Calls
2

Parameters

All of the existing outbound call parameters will work. In addition, we provide some specific values for certain parameters to help you generate success and failure cases.

From

Your test credentials don't have access to any valid 'From' phone numbers on your real account. Therefore the only phone number you should use as a 'From' number is the magic number listed here.

Value	Description	Error Code
+15005550001	This phone number is invalid.	21212
+15005550006	This number is a valid `From` number for your account.	No error
All Others	The phone number is not verified for your account.	21210

To

Value	Description	Error Code
+15005550001	This phone number is invalid.	21217
+15005550002	Twilio cannot route to this number.	21214
+15005550003	Your account doesn't have the international permissions necessary to call this number.	21215
+15005550004	This number is blocked for your account.	21216
All Others	Any other phone number is validated normally.	Input-dependent

Example 1

Successfully enqueue an outgoing call. Use the magic number +15005550006 as the From number and any regular number as the To number.
