# رمز الدعوة

## 📧 ما هو رمز الدعوة؟

عنصر أمان رمز الدعوة سيتحقق من رمز الدعوة الذي تم إرساله إلى المستجيب باستخدام [البريد الإلكتروني](/ar/form-management/campaigns/campaign/email-distribution.md) أو [sms](/ar/form-management/campaigns/campaign/phone-sms-distribution.md) الحملات. 

{% hint style="warning" %}
الأكواد المولدة أثناء [الحملات](/ar/form-management/campaigns.md) يمكن استخدامها مرة واحدة فقط لإجراء الاستبيان.
{% endhint %}

## 🔅خصائص كلمة المرور

* **`فقط المستلم المدعو يمكنه المشاركة`** يمكنك فتح استبيانك للمستجيبين الذين لم يتلقوا أي رمز دعوة أو فقط للمستجيبين الذين لديهم رمز دعوة صالح من [الحملة](/ar/form-management/campaigns.md). لاحظ أنه إذا لم يتم تحديد هذا الخيار فالمستجيب دون رمز سيتمكن من إجراء الاستبيان عدة مرات بينما المستجيب الذي لديه رمز دعوة صالح سيتمكن من إرسال إجاباتهم مرة واحدة فقط.

{% hint style="success" %}
يمكن استخدام عنصر الأمان هذا كمزوّد [key provider](/ar/form-management/security/key-provider-concepts.md).
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ngsurvey.com/ar/form-management/security/security-items/invitation-code.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
