The return of the Developers blog!

CCP Zelus | 2024-02-27 00:00
Greetings, developers! Today's post covers Plans for developer-related news, an SDE update and clearing up an old "Temporary" alert that existed here. News update: We know it's been a long time since this page was updated, but it's time we have a home for third-party developer-related content once again. We had been using a combination of the forums, Tweetfleet Slack and Discord to convey messages, but having an RSS news feed enabled post and a clean-from-clutter central location for information was the most requested thing from the community, so resurrecting this blog, as it has all the desired functionality seems to be the best avenue to facilitate that request! SDE: This is a two-fold announcement - the SDE with the updates from the balance patch from 20 February 2024 is now available at ... read more

SSO Endpoint Deprecations

CCP Convict | 2021-10-07 13:06
Hi developer friends! We'd like to inform you of upcoming SSO changes which might affect your application if you are developing 3rd party apps using ESI or using the EVE SSO for user authentication. We'll be making the following changes on November 1st 2021. Deprecating obsolete endpoints The old OAuth endpoints oauth/authorize, oauth/token and oauth/verify will be deprecated. You should move your application over to v2/oauth/authorize and v2/oauth/token instead. The oauth/verify endpoint will also be deprecated, since the v2 endpoints return a JWT token, enabling your applications to validate the JWT tokens without having to make a request to the SSO for each token. Applications can fetch the required EVE SSO metadata from to be able to validate JWT token signatures client-side. The deprecated endpoints might be removed at any given time ... read more

V4 of ESI public character information to be removed on 21.10.2021

CCP Convict | 2021-09-29 00:00
On 30 July 2020 in the ESI changelog we announced the deprecation of v4 version characters/{character_id}  ESI route on 15 September and subsequent removal on 21 September. Unfortunately we still see heavy traffic hitting that route which as of now has legacy status. Accordingly we've decided to postpone the (admittedly quite abrupt) removal. Its been rescheduled and now it will happen on 21st October 2021.  Please spread that information if you know any developer that might not follow changelog and/or Tweetfleet. read more

ESI Step by Step - SSO to Authenticated Calls

Team Tech Co | 2021-09-27 13:15
This blog post is part of a series of blogs examining best practices for ESI development. Each blog will be published on the 8th of each month during the journey towards XML API and CREST’s termination date. The legacy APIs will be terminated on May 8th, 2018, or earlier if metrics signal a trivial level of usage. Deprecated Information The information presented on this page is depreciated. Please see for up-to-date information. Last month, we talked about auto generating a client library for ESI using Swagger Codegen. This month we will expand on this by stepping through the SSO authentication flow and using that authentication to make a call to the ESI endpoint /characters/{character_id}/standings. Typically, one would set up a server to handle most of this process, but today we're ... read more

ESI Best Practices: Generating Code With Underscore Routes

CCP Bartender | 2021-03-11 17:22
This blog post is part of a series of blogs examining best practices for ESI development. Each blog will be published on the 8th of each month during the journey towards XML API and CREST’s termination date. The legacy APIs will be terminated on May 8th, 2018, or earlier if metrics signal a trivial level of usage. This blog explains best practices for autogenerating language specific clients from the ESI swagger spec. When generating code from one of the named routes (e.g., you may have noticed the resulting client library uses /latest as the version in all its URL calls. You can see why if you look at this fragment of the swagger spec from the above URL: { "basePath": "/latest", "host": "", "info": { "description": "An OpenAPI for ... read more

From Image Server to a Whole New Image Service

CCP Convict | 2021-03-11 16:13
As outlined by the previous blog, we’re upgrading the image server to an entirely new service that better fits the modern developer environment and needs. This means a friendlier, RESTful API, dynamic resizing, multi-tenancy support, and all these will be served through a global CDN. A New Domain Initially, we thought about sharing the same domain as the previous image server, but the change is way too subtle. So we will use a completely new domain for the new image service: Actually, the new service has already been deployed and running for a while, so go ahead and give it a try! It has some documentation with a very “minimalistic design” for now, which will likely be improved in the future. The New APIs    There are two main APIs in ... read more

REMOVAL of scopes from SSO

CCP Convict | 2020-03-05 00:00
On 8 April 2020, we will be making the following change:   REMOVAL of scopes from SSO esi-corporations.read_outposts.v1; esi-corporations.write_structures.v1. These scopes have not served any purpose for a long time now but we see that some applications still request them. If those applications aren't updated they will break after scopes removal. read more

Removing Datasource Singularity

Team Tech Co | 2020-01-13 00:00
Removing Datasource Singularity In our efforts to increase ESI production stability, and limit our maintenance overhead, we will be removing Singularity as an available datasource for ESI production. This action is planned to take effect during downtime tomorrow, 14th of January 2020. -- Team Tech Co Want to be part of the ESI conversation?

Temporary blackout of ESI-bookmarks

Team Tech Co | 2019-11-25 00:00
Temporary blackout of esi-bookmarks With the coming changes to our bookmark systems, and how internal schedules have lined up, we will be temporarily shutting down esi-bookmarks routes to re-implement them for the new system. This will result in empty list returns to reduce the impact on third party developers. The affected routes are: /characters/{character_id}/bookmarks/ /characters/{character_id}/bookmarks/folders/ /corporations/{corporation_id}/bookmarks/ /corporations/{corporation_id}/bookmarks/folders/ The new character routes will be deployed as soon as possible, with a new data schema, so that pilots can access all their new bookmarks, as well as their folders. The corporation endpoints will remain closed as the new bookmarks system does not call for their reimplementation. We apologize for any inconvenience caused by this temporary blackout and hope to have services restored ... read more

Upcoming changes to the Image Export Collection

Team Tech Co | 2019-07-10 00:00
Greetings developers!   As was mentioned at EVESterdam 2019 at the start of the third party developers panel, we're looking into deprecating the IEC and upgrading the image server to better support cases that people were using the IEC for. This will remove the need for a lot of work to be done every release by team TriLambda, as the IEC generation pipeline is very old and radically different from EVE's modern graphics processes.   ... read more
