What is the "repository ID" discussed in the Travis-CI API?

Question

To get a list of builds using the TravisCI API described here, it says that you need to put the repository ID in the request address.

I'm wondering, what is this ID, and where do I find it? Does it differ from the repository slug, which is username/reponame?

Answer 1

The repository ID is the repo key which is shown in Travis CI API responses.

This can be either retrieve by:

$ curl -L http://api.travis-ci.org/repos/user_name/repo_name

or if you've travis command installed, try:

$ travis show -r user_name/repo_name

Here is corresponding code in Ruby:

require 'travis'
repos = Travis::Repository.find_all(owner_name: 'user_name')
repos.each do |repo|
  puts repo.slug
end

^{In above examples, change user_name and repo_name into the right values.}

Answer 2

Reading through the TravisCI API, the repository ID is different from the slug. It is a number assigned to the repository by Travis and unrelated to the Github repository ID.

For example: curl https://api.travis-ci.org/repos/schwern/URI-Find will return...

{ "id":527875, "slug":"schwern/URI-Find", "description":"Perl module to find URIs in arbitrary text", "public_key":"...", "last_build_id":29287626, "last_build_number":"10", "last_build_status":0, "last_build_result":0, "last_build_duration":28, "last_build_language":null, "last_build_started_at":"2014-07-07T03:43:28Z", "last_build_finished_at":"2014-07-07T03:44:03Z" }

You can use the id to access the repository as well. curl https://api.travis-ci.org/repos/527875 will return the same thing.

As you can see with https://api.github.com/repos/schwern/URI-Find the Travis repository id differs from the Github repository id.

I assume the advantage of using the id vs the slug is the slug may change, repositories can be renamed and ownership transferred, but the id presumably will not.
