# Execution Resource

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.

To authenticate requests to the Twilio APIs, Twilio supports [HTTP Basic authentication](https://en.wikipedia.org/wiki/Basic_access_authentication). Use your *API key* as the username and your *API key secret* as the password. You can create an API key either [in the Twilio Console](/docs/iam/api-keys/keys-in-console) or [using the API](/docs/iam/api-keys/key-resource-v1).

**Note**: Twilio recommends using API keys for authentication in production apps. For local testing, you can use your Account SID as the username and your Auth token as the password. You can find your Account SID and Auth Token in the [Twilio Console](https://www.twilio.com/console).

Learn more about [Twilio API authentication](/docs/usage/requests-to-twilio).

> \[!WARNING]
>
> When triggering flows with the API, don't forget to also configure your Twilio 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 call back to your IVR.

> \[!CAUTION]
>
> The `contact_sid` property has been deprecated and will be replaced with a static placeholder value in the v1 API. Use `contact_channel_address` instead to uniquely track contacts. For the best experience and latest features, [upgrade to the v2 API](/docs/studio/rest-api/v2).

## Subscribe to Real-time Studio Events

[Try Studio Events](https://www.twilio.com/docs/studio/user-guide#subscribing-to-flow-events-with-event-streams)

You can now subscribe to Studio Events for Executions and Steps instead of polling via the REST API. Simplify your data ingestion with [Event Streams for Studio](/docs/studio/user-guide#subscribing-to-flow-events-with-event-streams).

## Update an Execution

`POST https://studio.twilio.com/v1/Flows/{FlowSid}/Executions/{Sid}`

An active Execution can be updated to "ended" using the REST API. Once ended, subsequent widgets in the Flow are not processed, and any new events that Studio receives for that Execution are rejected.

### Path parameters

```json
[{"name":"FlowSid","in":"path","description":"The SID of the Flow with the Execution resources to update.","schema":{"type":"string","minLength":34,"maxLength":34,"pattern":"^FW[0-9a-fA-F]{32}$"},"required":true},{"name":"Sid","in":"path","description":"The SID of the Execution resource to update.","schema":{"type":"string","minLength":34,"maxLength":34,"pattern":"^FN[0-9a-fA-F]{32}$"},"required":true}]
```

### Request body parameters

```json
{"schema":{"type":"object","title":"UpdateExecutionRequest","required":["Status"],"properties":{"Status":{"type":"string","enum":["active","ended"],"description":"The status of the Execution. Can be: `active` or `ended`.","refName":"execution_enum_status","modelName":"execution_enum_status"}}},"examples":{"update":{"value":{"lang":"json","value":"{\n  \"Status\": \"ended\"\n}","meta":"","code":"{\n  \"Status\": \"ended\"\n}","tokens":[["{","#C9D1D9"],"\n  ",["\"Status\"","#7EE787"],[":","#C9D1D9"]," ",["\"ended\"","#A5D6FF"],"\n",["}","#C9D1D9"]],"annotations":[],"themeName":"github-dark","style":{"color":"#c9d1d9","background":"#0d1117"}}}},"encodingType":"application/x-www-form-urlencoded","conditionalParameterMap":{}}
