Summary

Document that automatic preview deployments are not created for pull requests opened from forked repositories, and list the supported workarounds.

Changes

  • Added a warning callout under Automatic previews on the Preview deployments page explaining the fork limitation.
  • Linked to the manual preview flow and the Trigger preview deployment API as workarounds, with a note not to expose API keys to workflows running untrusted fork code.

Context

Support has had to hand-type this explanation for customers whose external contributors open PRs from forks and see no preview link. Documenting it inline lets readers self-serve.


Note

Low Risk
Documentation-only change with no product or runtime impact.

Overview
Adds a Warning under Automatic previews on the Preview deployments page so readers know fork-based PRs do not get automatic preview links (Mintlify app is not on the fork).

The callout lists three workarounds: open the PR from a branch on the origin repo, have a maintainer create a manual preview, or trigger a preview via the Trigger preview deployment API from trusted CI—with a note not to expose API keys to workflows running untrusted fork code.
