Verify Push Webhooks
概要
Webhooks are a general pattern for how one system can be notified of events generated by another system in real-time. In the case of Verify Push, your app backend can be notified when a Factor has been verified or when a Challenge has been approved by the Verify Push service, so that it knows to advance the user to the next step in your flow. This is more real-time and efficient than constantly polling the Verify Push API for the status of a Factor or Challenge.
To configure webhooks, follow these steps:
- Configure a webhook in your Verify Service via the Console UI
- Receive, parse, and verify a webhook
- Manage webhooks via Verify API (optional)
1. Configure a webhook in your Verify Service
前提条件
- Create a Verify Service.
- Create a REST API endpoint in your app backend that can receive HTTP POST requests.
Configure a webhook via Console UI
You can configure a webhook either via UI or API. We'll show the UI option first and then the API option later.
- Go to Twilio Console > Verify > Services > Your Service > Webhooks.
- Go to Create new webhook and complete the form.
- Enter a friendly name that will help you identify the webhook in the future.
- Select the events that you want to receive. See definitions in the Webhook Events table below.
- Enter the URL of your app backend's API endpoint.
- Webhook version is set to v2 automatically. v1 is legacy and may be removed in the future. See below for the events fields per version.
- Click Create to finish creating your webhook.
Webhookイベント
| イベント | 概要 |
* |
Fires when any of the following events occur. |
factor.created |

factor.verified |

factor.deleted |
Fires when a factor was deleted from an entity. |
challenge.approved |

2. Receive, parse, and verify a webhook
When Twilio makes an HTTP request to your app backend, it will include parameters related to the event that triggered it:

Verify the webhook's signature to confirm that it came from Twilio
- Each HTTP request is issued with the
Content-Typeheaderapplication/x-www-urlencodedand signed with anX-Twilio-SignatureHTTP header. - Twilio uses the parameters sent in the webhook and the exact URL your application supplied to Twilio to create this signature. The signature uses the
HMAC-SHA1hashing algorithm with your Twilio account's auth token as the secret key. - Your application can verify that this signature is correct using the server side Twilio SDKs. You will need your account's auth token, the value of the
X-Twilio-SignatureHTTP header that Twilio passed to you, the URL that Twilio sent the webhook to, and all of the parameters sent by Twilio. - For more information, check out our guide to Getting Started with Twilio Webhooks and Validating Requests are coming from Twilio. Find other webhook pages, such as a security guide and an FAQ in the Webhooks section of the docs.
