Release info

99Stack API was originally released in Q1 2019 as a beta version with reservation for future changes. On this page you'll find documentation for all available versions of the API. Including important updates and changes. All documentation found here are synced with our public Github repository at: github.com/99stack/api-docs. Contribute and report issues there.


The version is always presented as the first argument in the three part URL: version -> object -> function. Current latest version is /v1, this number will increase when any major change is made, such as changes in input, output, method, response codes or functionality. Please check this page regularly for a summary of the latest updates.

The first stable release is planned for Q1-Q2 2020 and will ensure that there are well established standards for input, output, response codes and methods to avoid confusion and unexpected errors. See below for current progress.


  • Update all input and output to JSON
  • Update all methods and validate methods
  • Implement rate limits for security
  • Correct http response codes
  • Changing all timestamps to ISO-8601 UTC+00:00 format, also including timestamp in all requests with a meta object
  • Respond with an error object on input errors informing you about exactly what's wrong and how to fix it
  • Change the generic response format to a "response" object containing "text", "code" and "type". A response can then contain both a response message with status code and "errors"
