Your inputs
Run the API Permission Matrix
Use one stated integration boundary and measurement period. Every entered value changes the result, calculation, or recommended action.

How it works
Enter method-specific evidence
Replace the example values with current evidence for this workflow: Maps roles or scopes to resources, fields, operations, environments, and conditions.
Review the transparent result
The result shows its arithmetic and assumptions, then identifies the most important gap or next implementation decision.
Frequently asked questions
What does API Permission Matrix calculate?
It converts the entered API or integration evidence into a bounded estimate, coverage measure, or decision signal for this purpose: Maps roles or scopes to resources, fields, operations, environments, and conditions.
What period and scope should I use?
Use one interface or workflow and one recent, representative period. Keep volumes, costs, consumers, tests, and evidence aligned to that same boundary.
Is the result a security or architecture approval?
No. It is transparent planning guidance based on your inputs, not a certification, guarantee, legal opinion, security review, or production approval.
When should I update the API Permission Matrix?
Recalculate when scope, traffic, consumers, contracts, provider limits, schemas, costs, evidence, ownership, or operational requirements change materially.
