Connect App limitations
Connect Apps do not have access to the full functionality offered by Twilio services. Please see Twilio Connect Limitationsfor full details.
Twilio Connect lets your customers grant you access to their Twilio accounts so that your application — your ‘Connect App’ — can buy phone numbers, make phone calls, and send SMS. Because your customers are using their own Twilio account, you don’t need to worry about billing them for their usage of Twilio services: Twilio will charge your customer directly.
Additionally, users can grant your Connect App access to their Twilio call and SMS log data. With this information, you can implement analytics and other read-only use-cases.

Manage your Connect Apps
Create Connect Apps using the Apps page in the Console.
You may update your Connect Apps through the same page, or with the Connect REST API.
Only upgraded accounts can create Connect Apps.
How it works
When creating your Connect Apps, there are two different permissions you can request from your users:
- Charge account for usage allows your application to buy phone numbers, make phone calls, send text messages, and perform other tasks that result in Twilio billing the user directly.
- Read all account data allows your application to access call, SMS, and other logs for analytics and other read-only use-cases.
These permissions are not mutually exclusive. You select both Charge account for usage and Read all account data when setting up your Connect App, or select one at the start and add the second later. However, if you change your Connect App permissions, you will not be able to use any new permission until the user reauthorizes your Connect App.
See the permissions section, below, for more details.
When you create your Connect App, you will be given a snippet of HTML to drop into your webpage. This HTML will display a Connect button that users can click to authorize your Connect App to use their Twilio account. If a user doesn’t yet have a Twilio account, they will be prompted to sign up.
When a user clicks the Connect button, they will be asked to authorize your Connect App according to the permissions you selected when you set the App up. After the user authorizes your Connect App, Twilio will redirect their browser to a URL that you specify during setup: the Authorize URL under Endpoints. This redirect will include
AccountSid as a GET query string parameter. The value of
AccountSid is the SID of an sub-account set up under the user’s Twilio account. You authenticate Connect requests made by your app with that Account SID and your own Auth Token.
If you add a query string parameter called
state to the target URL of the Connect button, Twilio will also pass that parameter back in the request it makes to your Authorize URL. This parameter is useful for passing metadata, like a customer’s username or some other unique identifier, to your cloud.
If you have Charge account for usage permission (
"post-all" in the API), you can make
POST requests to the user’s account’s subresource URLs to buy numbers, make phone calls, and send SMS messages on their behalf.
If you have Read all account data access (
"get-all" in the API), you can make
GET requests to the
/accounts endpoint to see all the user’s accounts. You can also make
GET requests to any subresource owned by those accounts.
You can use the existing Twilio helper libraries to make authorized requests to your users’ Twilio accounts. Just use the
AccountSid value provided by the request Twilio makes to your Authorize URL after the user has granted your Connect App access rights.
Twilio Connect is a new way of thinking about your applications. Here are some best practices that you should follow to make sure your Connect App is both secure and error-free.
Do place your Connect button behind some form of authentication
Twilio Connect allows end-users to authorize your application to make requests on their behalf, but it does not serve as an authentication mechanism for your end-users. As such, your application should provide its own authentication mechanism. For more information please read the How it works section.
When presenting your Connect button, you should inform users that Twilio will bill them directly for your Connect App’s voice and SMS usage.
Do redirect to another page after your Authorize URL
Your Authorize URL should only be used by your Connect App. We will pass your user’s Account SID to your Authorize URL. After you store the user’s Account SID, you should redirect the user to a follow-on page.
Do have a Deauthorize URL
When a user revokes permission your Connect App’s permissions, Twilio will make an HTTP request to any URL you specified as a
DeauthorizeCallbackURLvalue. You should use this request to updated your user database to reflect the loss of permissions.
Do have a FAQ
Include a FAQ to let your customers know they they are required to create and upgrade a Twilio account, if they haven’t done so already.
Do not make a user’s Account SID available to others
Although all requests made to the Twilio API must be authenticated with your own Auth Token, you should treat the Account SID you receive from Twilio as you would other user data.
Do not change your Connect App permissions haphazardly
If you change the permissions that your Connect App requires, you will not be able to use them until your user reauthorizes your Connect App. Changing your Connect App permissions frequently may lead to situations where you’re not sure what permissions you have for a particular account. We recommend you change permissions only when a new feature requires it.
There are two permissions available for Twilio Connect Apps:
Read all account data
This allows your Connect App to see all the user’s data, including calls, SMS, recordings, and transcriptions. Your Connect App will also have access to Twilio data generated by other Connect Apps, any subaccount, and the parent account. A Connect App with this permission alone will only be able to perform
GET requests on the user's accounts.
Charge account for usage
This allows your Connect App to perform actions that charge your user’s Twilio account such as make and receive phone calls, send and receive SMS messages, and buy phone numbers. Your Connect App will not have access to resources in the user’s parent account, like phone numbers. Instead, your Connect App must buy phone numbers on behalf of the user, using the Account SID passed to your Authorize URL.
The Account SID that Twilio returns to your Authorize URL — as the value of
AccountSid — is a subaccount just for your application within the user's account. This allows your Connect App to buy numbers and make calls without other Connect Apps modifying your data.
Connect App configuration options
Connect Apps have a variety of configuration options that Twilio uses in different parts of the authorization flow and the account portal.
|Friendly Name||The name of your Connect App. It will be displayed on the authorization screen and the user’s list of authorized apps. Required|
|Application Logo||A logo or picture associated with your Connect App. It will be displayed on the authorization screen and in the user’s list of authorized apps. Required|
|Company Name||The name of the Connect App’s developer, ie., your company. Displayed on the authorization screen and the user's list of authorized apps. Required|
|Description||A brief description of what your Connect App does. Displayed on the authorization screen|
|Homepage URL||The homepage of your Connect App, displayed in the user’s list of authorized apps|
|Terms of Service URL||The URL where users can read your Connect App’s Terms of Service. It will be displayed in the user’s list of authorized apps|
|Authorize URL||The URL to which the user will be redirected after they go through the authorization flow. If the user approves access for your Connect App, they will be redirected to this URL with their Account SID as an HTTP
If a user chooses to decline authorization they will be redirected to this URL with a single parameter:
|Deauthorize URL||The URL to which Twilio makes a request when a user revokes access to your Connect App. This is a server-to-server request; your users will never be directed to this location.
Two parameters will be sent as part of this request:
|Deauthorize URL HTTP Method||The HTTP method used when making a request to your Deauthorize URL. You can select either
|Access Required||This defines the types of API access your Connect App will require. Read the permissions section for more details.|
