What the customer provides

Bring your current business identifiers, responsible users, policy decisions, representative documents and authorized connection details. Keep credentials in the designated secure configuration rather than in a spreadsheet, prompt or source repository.

Changing it afterwards

Use Proto to propose a change on a reviewed configuration branch. Check its effect on existing records, role boundaries, automation and reports before release. Preserve the previous source revision and the migration decisions needed to explain historical work.

Say what you need"Add a second approval above 10,000." Plain language.
2
Review the branchThe change lands on a branch with the diff and a test run.
3
ReleaseMerged into your workspace. Every user gets it.
