# Developing Apps for Common Use Cases

While the Wix dev platform allows you to create various types of apps, you may choose to develop an app that meets a common need, such as fulfillment or invoicing. Below is a list of app types for common use cases. For each use case, we list key REST APIs and webhooks you might use to implement their basic functionality as well as the permissions required for these APIs and webhooks.  

This reference is intended as a helpful starting point, but keep in mind that your specific app may require additional resources. Note that the following are [REST resources](https://dev.wix.com/docs/rest.md).

## Considerations when developing your app

When developing your app, make sure to:

+ Include the App Instance ID in API calls to [identify app users](https://dev.wix.com/docs/build-apps/launch-your-app/pricing-and-billing/identify-and-manage-app-users.md).
+ [Set up your app pricing](https://dev.wix.com/docs/build-apps/launch-your-app/pricing-and-billing/about-pricing-plans-and-business-models.md).
+ Read through our [guidelines](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/app-market-guidelines.md) and our [Partner Agreement](https://dev.wix.com/docs/build-apps/launch-your-app/legal-and-security/wix-app-market-partner-agreement.md).
+ Review our [App Checks and Testing Guide](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/app-checks-and-testing-guide.md) and [test your app](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/test-your-app-on-a-premium-site.md) thoroughly.

When you're ready, [submit your app](https://dev.wix.com/docs/build-apps/launch-your-app/app-distribution/submit-your-first-app-version.md) for review.
