In another post, we described how to adjust an object’s access control list (ACL) using Backendless Console. As we mentioned, in addition to Backendless Console, the object’s permissions can be controlled using API.

As data objects are being saved or updated with the API requests some properties of the objects may not have a value assigned to them. It may be necessary that for those properties a default value is assigned. This is identical to how relational databases may have a default value for a column.

Once a user of a Backendless-powered app logs in, a session is established. For a variety of reasons, including application security, it is best not to allow users to remain logged in indefinitely. Therefore, every session has an inactivity timeout timer that is reset with every new API call made within the session. When the…

Backendless provides an easy-to-use API to introspect data tables. Given a table name, the API provides information about table columns, their names, data types, default values, etc. If a column represents a relationship, it is properly denoted as such in the provided information.

Backendless Geolocation allows you to map a location to a data object. This feature can lead to a lot of interesting opportunities. For example, consider a taxi booking service like Uber. You may have multiple cars/drivers available for hire as well as customers putting in pickup requests. Both drivers and customers may be represented by…

There are two types of custom business logic (Cloud Code) scripts supported by Backendless – API event handlers and timers. In this post, we will review the latter. A timer is a server-side program deployed to the Backendless server infrastructure which is scheduled to run on a pre-defined schedule.

Backendless Console is a development tool that is also the frontend for your backend. It is quite common for more than one developer to need to access the Console to view data, test queries, or adjust the security settings. The Console and the backend are built in a way where concurrent developer logins to the…

In another article, we reviewed how to register app users with the API. By default, a Backendless backend declares a user entity with three properties: email, password, and name. The “email” property is configured as identity by default, meaning its value should be passed into the login API request.

When saving or updating a data object in a persistent storage, it is often necessary to make sure a property follows a particular data format. For instance, properties like email address, a US phone number, a bank account number, a URL and many others may be validated with regex (a regular expression). Backendless makes it…
