The features described in this section are only available once your package has gone through a Salesforce-driven process known as a security review, which is initiated via your listing when logged into AppExchange. Unless you plan to give your package away for free, there is a charge involved in putting your package through this process.
While the review is optional and there is nothing stopping you from distributing your package installation URL directly, keep in mind that Salesforce displays a banner during installation and, once installed, it informs admins that the package has not gone through a security review. Furthermore, you will not be able to benefit from the ability to list your new application on AppExchange for others to see and review. More importantly, you will also not have access to the following features to help you deploy, license, and support your application. The following is a list of the benefits you get once your package has passed the security review:
- Bypass subscriber org setup limits: Limits such as the number of tabs and Custom Objects are bypassed. This means that if the subscriber org has reached its maximum number of Custom Objects, your package will still install. This feature is sometimes referred to as Aloha. Without this, your package installation may fail. You can determine whether Aloha has been enabled via the Subscriber Overview page that comes with the LMA application, which is discussed in the next section.
- Licensing: You are able to utilize the Salesforce-provided License Management Application (LMA) and Feature Management Application (LFM) in your LMO.
- Subscriber support: With this feature, users in the subscriber org can enable, for a specific period, a means for you to log in to their org (without exchanging passwords), reproduce issues, and enable much more detailed debug information, such as Apex stack traces. In this mode, you can also see custom settings that you have declared as protected in your package, which is useful for enabling additional debug or advanced features.
- Push upgrade: Using this feature, you can automatically apply upgrades to your subscribers without their manual intervention, either directly through the Push UI, on a scheduled basis, or via the Push API. You may use this for applying either smaller bug fixes that don't affect Custom Objects or APIs, or for deploying full upgrades. The latter requires careful coordination and planning with your subscribers to ensure that changes and new features are adopted properly.
- Usage Metrics: This feature provides additional analytics on how customers are using your application, such as the objects they are using and the parts of the user interface they are accessing. Your Product Management team can use this to drive roadmap priorities and track the adoption of new features.
This book focuses on building a fully native application; as such, additional work involved in so-called "hybrid" applications (where parts of your application have been implemented on your own servers, for example) are not considered here. However, keep in mind that if you make any callouts to external services, Salesforce will also most likely ask you and/or the service provider to run a BURP scanner, to check for security flaws.
Make sure you plan a reasonable amount of time to go through the security review process; it is essential that you initially list your package, though if it becomes an issue, you have the option of issuing your package install URL directly to initial customers and early adopters.
