+# Cross-Platform Edge SDK Verification
+## Requirements
+1. A working Identus Mediator and an Identus Cloud Agent.
+2. A holder who already has a JWT Credential issued by a known issuer (prism:did) [Holder A]
+
+
+> NOTE:
+>
+> Please follow the [Quick started guide](../../docs/quick-start) to complete steps 1, 2, 3
+
+
+## Flow
+1. The verifier will need to generate an invitation url as follows:
+
+```
+curl --location 'http:///cloud-agent/present-proof/presentations/invitation' \
+--header 'Content-Type: application/json' \
+--data '{
+ "goalCode" : "present-vp",
+ "goal" : "Request proof of vaccination information",
+  "proofs": [],
+ "options": {

+    "domain": "https://prism-verifier.com"
+  }
+}
+```
+
+The response will look as follows:
+
+```

+
+The Verifier will make this available to the holder in shape of QA code, link, etc.
+
+2. The holder then opens its the Edge Agent Wallet SDK, "Connections tab" and will pase the invitation link in the field.
+
+Once the invitation is parsed, the user will then be able to see a new Verification request, choose one of the available credentials and send the proof as the verifier requested.
