# Portable Document A1 (PDA1) - credential schema ## When to use Use this skill when you issue or verify a **Portable Document A1 (PDA1)** credential. PDA1 is the EU social security document.

Use **staging** (`https://staging-api.igrant.io`) only when the integrator asks for it. A key works only in its own environment. ## Ask the integrator first Ask one question at a time. Wait for the answer. Give the recommended default with each question. Look up facts in the project (framework, environment variables, an existing
