Build in-meeting document signing
Meeting signing is a Microsoft Teams sample app that enables users to sign documents in real time scenarios. It provides enhanced experience by allowing the users to review and sign documents in a single session during meetings. This sample lets users electronically sign documents with their current tenant identity. The users can sign the following documents during meetings:
- Purchase agreements.
- Purchase orders.
The template is also applicable for other scenarios, such as for reviewing and approving code samples and collaborative documents. The users can customize to incorporate other types of signatures:
- Handwritten signatures.
- Certificate-based signatures.
This step-by-step guide helps you to build in-meeting document signing app. You'll see the following output after you've completed this guide:
Prerequisites
Ensure that you install the following tools to set up your development environment:
| Install | For using... | |
|---|---|---|
| Microsoft Teams | Microsoft Teams to collaborate with everyone you work with through apps for chat, meetings, and call all in one place. | |
| Visual Studio 2022 |
You can install the enterprise version in Visual Studio 2022, and install the ASP.NET and web development workloads. Use the latest version. | |
| .NET Core SDK | Customized bindings for local debugging and Azure Functions app deployments. Use the latest version or install the portable version. | |
| Dev tunnel | Teams app features (conversational bots, message extensions, and incoming webhooks) need inbound connections. A tunnel connects your development system to Teams. Dev tunnel is a powerful tool to securely open your localhost to the internet and control who has access. Dev tunnel is available in Visual Studio 2022 version 17.7.0 or later. or You can also use ngrok as a tunnel to connect your development system to Teams. It isn't required for apps that only include tabs. This package is installed within the project directory (using npm devDependencies). |
|
| Microsoft 365 developer account | Access to Teams account with the appropriate permissions to install an app. |
Note
After downloading ngrok, sign up and install authtoken.
Tip
Ensure the Microsoft Teams account isn't a guest account.
Set up your Teams development tenant
A tenant is like a space, or a container for your organization in Teams, where you chat, share files, and run meetings. This space is also where you upload and test your custom app. Let's verify if you're ready to develop with the tenant.
Check for custom app upload option
After creating the app, you must load your app in Teams without distributing it. This process is known as custom app upload. Sign in to your Microsoft 365 account to view this option.
Note
Custom app upload is necessary for previewing and testing apps in Teams local environment. Enable custom app upload to preview and test your app in Teams locally.
Do you already have a tenant, and do you have admin access? Let's check if you really do!
To verify upload apps in Teams:
In the Teams client, select the Apps icon.
Select Manage your apps.
Select Upload an app.
Look for the option to Upload a custom app. If you see the option, custom app upload is enabled.
Note
Contact your Teams administrator, if you don't find the option to upload a custom app.
