Examples
Keep development and production credentials separated
Create distinct Retell projects or explicitly named agent groups for
development, staging, and production. Each environment receives its own secret
reference and phone routing configuration, so a local test cannot accidentally
create a live call. Verify the separation by listing agents with the
development credential and confirming that production identifiers are absent;
promote configuration through a controlled CI environment instead of copying
keys between files.
