# App Channels Configuration
In this article, you will create a Communication App in the Partner Portal and declare which communication channels your app will handle. By the end of this article, your app will be registered and ready to receive message events from any merchant who installs it.
## Prerequisites
If you are new to Salla's Partners ecosystem, make sure you have the following before starting.
| Requirement | What you need to do |
|---|---|
| Partner account | [Sign up here](https://portal.salla.partners/) if you do not have one yet |
| Demo store | [Set up a demo store](https://salla.dev/blog/how-to-test-your-app-using-salla-demo-stores/) — you will use it to test with demo data |
| App Functions familiarity | Read the [App Functions reference](https://docs.salla.dev/1726817m0) if you have not built a function before |

If you have an existing communication app and a demo store ready, skip straight to [Configure Supported Features](#configure-supported-features).
:::
## Create a new app
Log in to the [Partner Portal](https://portal.salla.partners/).
Clicking on `+ Create New App`, this will open the Create App form where you can choose the App type. Choose the Public App type then click on Continue
Fill in the basic app information and choose the Communication App Category.
After completing the form click on the Create App button.
:::warning[Why app type matters]
Selecting Communication App is what enables the Supported Features section in your app settings. Without it, the channel configuration options will not appear and you will not be able to build a communication app.
:::
## Configure Supported Features
Supported Features declare which communication channels your app handles. When a merchant installs your app and sets it as their active handler, Salla routes all matching messages through your App Function — your app takes full ownership of that message type.
:::danger[Action Required]
Your app cannot go live until at least one Supported Feature is selected.
:::
In the Partner Portal, open your newly created communications app and scroll down to the **Supported Feature** section.
Click the **Supported Feature** button to open the channels selector. Then choose the features supported by your App and click Save.
| Tab | Feature | What your app handles |
|---|---|---|
| SMS | **Local SMS** | All SMS messages to KSA numbers (`+966...`) |
| SMS | **International SMS** | All SMS messages to numbers outside KSA |
| Email | **Email** | All email messages |
| WhatsApp | **WhatsApp** | All WhatsApp messages |
:::check[Handling multiple channels]
You can select multiple features. For example, tick both **Local SMS** and **International SMS** if your provider handles both. Each feature you select means your app takes full ownership of that message type for every merchant who installs it.

## Setup Webhook Events
ADD A SCREENSHOT FOR CUSTOMER READ_WRITE
After creating the communication app you will need to set it up according to the your app needs. First add your webhook url *(you can use [webhook.site](https://webhook.site/) for testing purposes)*. Then Scroll down to the Store Events in Webhooks/Notifications section and click on Add Events.
A pop-up page will display the Store Events list, here you can click on the Communication then tick the events you want to listen to.
## What you have now
At this point you should have the following ready:
- Communication app created and configured with supported channels
- Demo store
- Webhook server and events ready
