> Setup in-app purchases for iOS
We are using [RevenueCat](https://www.revenuecat.com/) to handle in-app purchases.
* Relevant Links: [RevenueCat Docs](https://www.revenuecat.com/docs)
First, you need an Apple Developer Account to setup in-app purchases.
## Setup
Firstly, you need to create a new app in AppStoreConnect.
After creating the new app button, you will see the following screen.
Please click the `Certificate Identifiers & Profiles` link.
Fill the App Bundle ID with your app's bundle ID. like: `com.shipmobilefast.app` We mentioned this bundle ID in the [Quick Start section](/quickstart).
* I mean this is your app's bundle ID.
After filling the bundle ID, click the `Continue` button and turn back to New App Adding screen.
Please click the `Create` button.
After clicking the `Create` button, you will see the following screen.
* Go to the `App Information` tab and scroll down to the `App Specific Shared Secret` section.
* Click the `Manage` button and copy the `App Specific Shared Secret`.
After clicking the `Manage` button, please click the `Generate` button.
After clicking the `Generate` button, you will see the following screen.
Please copy the `Shared Secret` value and keep it in a safe place. We will use it in the next step.
After copying the `Shared Secret` value, go back to the RevenueCat dashboard and paste it in the `App Specific Shared Secret` field.
Please click the `Set` button. But don't close this tab. If you try to `Save Changes`, you will lose the `Shared Secret` value and you will get an error.
After clicking the `Set` button, you will see the following screen. Now go to the `App Store Connect` dashboard again.
After going to the `App Store Connect` dashboard, go to the `Users and Access` section.
1. First copy your Issuer ID and paste it on RevenueCat `Issuer ID` field.
2. Click the `+` button to create a new key and Download it.
Please click the `In-App Purchase` tab under the `Keys` section.
After clicking the `+` button, download the .p8 file and save it in a safe place. Then go back to the RevenueCat dashboard.
