Builds and TestFlight
These commands use App Store Connect API-key authentication.

List builds across accessible apps:

TestFlight testers
List testers, optionally filtered by app:
Invite a tester to an external beta group. Internal groups are unsupported by this command. The email address is positional, and --group expects the group's App Store Connect resource ID:
slowlane asc testflight invite new.tester@example.com \
--group GROUP_RESOURCE_ID \
--first-name Taylor \
--last-name Example
Slowlane reuses an existing tester when found and ensures membership in the requested group. Apple controls invitation delivery according to build readiness and notification settings; successful membership does not guarantee that an email has been sent.
TestFlight groups
Use the ID shown by this command when inviting a tester.
