# Twilio / Sendgrid

Ermöglicht ngSurvey die Verwendung der Twilio/SendGrid Messaging-API.

## 🔅 Twilio/SendGrid-Eigenschaften

* **`API key`** das von Ihrem Twilio-Konto bereitgestellte Token zum Senden von E-Mails.
* **`Webhook-Handler`**kann in Ihrem Twilio-Konto verwendet und eingerichtet werden, um zurückgegebene und ungültige E-Mails zu verfolgen.
* **`Global auf einen Absender beschränken`** wenn aktiviert, ermöglicht dies die Angabe einer einzigen E-Mail-Adresse und eines Namens, die für alle E-Mail-Versandprozesse innerhalb von ngSurvey verwendet werden. Ist diese Option aktiviert, verwendet ngSurvey ausschließlich die angegebene E-Mail-Adresse, nutzt nicht mehr die E-Mail-Adresse des Benutzerkontos und erlaubt Benutzern nicht, für E-Mail-Funktionen wie Kampagnen oder Aufgaben eine andere E-Mail-Adresse einzugeben.

## 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/de/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.
