The API is currently being updated and this information may change at any time until it is completed. This information is being written as the API is being rewritten.

Access Levels

There are 2 different types of access levels available from the API. There is a public access level and pack developer access level.

Public Access Level

This access level is available to all and doesn't need an API key to access. Information supplied to the Public Access Level is limited and there are lower hourly request allowances.

Pack Developer Access Level

This access level is available to Pack Developers only and requires an API key to access, which can be obtained in your Settings page of the Admin Panel. Pack Developers will be able to control pretty much everything from the API and have higher hourly request allowances.

Request Allowances

Each level of access is limited by the number of requests they can make in a certain time period. In order to not reach these limits, make sure you're caching data and not fetching too often. Once your limit has been reached, you will receive a 429 Response Code and will be unable to do anything until an hour after your first request, which you can find a unix timestamp of when your hour resets in the response headers. Below you can find a table listing the different request restrictions in place.

Access Level Max Requests Per Hour
Public 300
Pack Developer 3,000

Rate Limiting Headers

Every request includes 4 headers to give you information about your rate limiting including the number of requests made, left and time until you can make more. See the table below for information on the headers.

Header Name What It's For
api-calls This is the number of calls to the API you've made in this hour session
api-calls-left This is the number of API calls you have left based upon your rate limiting
api-rate-limit This is your rate limit and is the maximum amount of API calls you can make within a set time limit (see above table)
api-rate-resets This is a unix timestamp for when your rate limiting will reset

How To Make An API Call

To make an API call, you simple need to make a call to https://api.atlauncher.com/v1/ with the appropriate path to what information your looking for. More information can be found throughout this API and in it's sub sections. If you are a pack developer or in our Partner Support Program and have an API Key, it must be specified by adding a header to your request of API-KEY

We provide RESTful functions using the GET, POST, PUT and DELETE headers.

Basic Returned Information

All requests to the API will return 4 things in an object encoded in JSON. $object is used to reference the decoded JSON string returned from the API.

Name Type Description
$object→error boolean If there was an error, this will return true, else it will be false
$object→code int The Response Code for the call
$object→message varies A string containing the error message, if any, else will be null
$object→data varies This is the Data returned from a successful API call. Will be null if there was an error, else will contain an object, array or string depending on the call. See the specific page for what it will return

__ Variables & Links

Some API calls have special variables starting with 2 underscores (__) which are special. Most notably the __LINK variable provides the URL to the given objects API path. Be it a version listing or a pack listing, this will provide you with a simple way to find the way to get more information about the given object you have received.


There are some packages you can use to make working with our API much easier for different programming languages. While this is a short list at the moment, if you write a package for a language to work with our API, please let us know by contacting us so we can add it to this list.

Please note this list contains unofficial packages and we cannot always guarantee they will keep updated or work as expected.
