# Twilio / Sendgrid

Permet à ngSurvey d’utiliser l’API de messagerie Twilio / SendGrid.

## 🔅 Propriétés Twilio / SendGrid

* **`API key`** le jeton fourni par votre compte Twilio pour l’envoi d’e-mails.
* **`Gestionnaire de webhook`**peut être utilisé et défini dans votre compte Twilio pour suivre les e-mails rejetés et invalides.
* **`Restreindre globalement à un seul expéditeur`** si activé, cela nous permet de spécifier un seul email et un seul nom qui seront utilisés pour tous les processus d’envoi d’emails dans ngSurvey. Une fois activé, ngSurvey utilisera uniquement l’email spécifié et n’utilisera plus l’adresse email du compte utilisateur, ni n’autorisera l’utilisateur à saisir un email pour les fonctionnalités d’email telles que les campagnes ou les tâches.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ngsurvey.com/fr/installation-setup/system-settings/mailing-server/iis-smtp-exchange-server-2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
