Execution

An Execution represents a specific person’s run through a Flow. An execution is active while the user is in the Flow, and it is considered ended when they stop or are kicked out of the Flow.

HTTP requests to Studio's REST API are protected with HTTP Basic authentication. To learn more about how Twilio handles authentication, please see our security documentation. You will use your Twilio account SID as the username and your auth token as the password for HTTP Basic authentication.

Important: When triggering flows with the API, don't forget to also configure your phone number with your Studio Flow! If you don't configure the phone number, users won't be able to reply to your messages or interact with your IVR.

date_created
date_time<iso8601> Not PII

The date and time in GMT when the resource was created specified in ISO 8601 format.

JSON data that will be added to the Flow's context and that can be accessed as variables inside your Flow. For example, if you pass in Parameters={"name":"Zeke"}, a widget in your Flow can reference the variable {{flow.data.name}}, which returns "Zeke". Note: the JSON value must explicitly be passed as a string, not as a hash object. Depending on your particular HTTP library, you may need to add quotes or URL encode the JSON string.

Example 1

              Create a new Execution with JSON data to be added to your flow's context. You will be able to access these parameters as variables inside your Studio flow.
