Travis CI API token generation – missing repo‑scoped permission boundary

Question

The goal is to configure Travis CI automation so that API tokens used for triggering builds or accessing repository data are limited to a single repository, adhering to a least‑privilege principle. Currently, token generation in the account settings produces an account‑wide token by default, and the public documentation does not specify whether a repo‑scoped alternative exists or how administrators can enforce such a boundary. This lack of a clear permission constraint leaves an unresolved decision about the default token scope and the configuration needed to restrict access.
Does Travis CI provide a way to generate API tokens scoped to an individual repository? If such tokens are not available, what configuration or workflow can be used to enforce least‑privilege access for automated builds? Should the token‑creation UI expose a repo‑scoped option by default to guide users toward the minimal required permission?

Direct answer
Travis CI Cloud does not provide a repository-scoped API token for general data access. The token generated in Account Settings → API Tokens is account-wide and grants access to all repositories and account actions. A separate repository token exists, but it is limited to triggering builds on the target repository and does not extend to other API endpoints.
Confirmed behavior and uncertainty
The current public Travis CI Cloud UI offers no per-repo selection during token creation. The repository token is intended solely for the POST /repo/:owner/:repo/requests endpoint. Whether Travis CI Enterprise exposes additional token scoping options is uncertain and should be verified in the enterprise interface.
Least-privilege workflow

If automation only needs to trigger builds, generate a repository token from Repository Settings → Tokens and use it with the build request endpoint.
For broader repository data access, use a GitHub App or OAuth token with the minimal required scopes (for example, repo:status or repo:pull_request) and inject it as a secure environment variable in the Travis job.
As an alternative, create a distinct Travis user account with restricted repository permissions and generate tokens from that account.

Verification
You can verify the account token's scope by attempting to call the Travis API for a repository outside the intended set; success confirms it is account-wide. For the repository token, confirm that POST /repo/:owner/:repo/requests succeeds while other endpoints fail.
UI recommendation
The token-creation UI does not currently expose a repo-scoped option by default. Adding such a control would align with least-privilege practices, but that change would need to come from Travis CI.
To refine the recommendation, please confirm whether your automation requires build-trigger-only access or broader repository data access.
