1. Sinch Dashboard

   • Go to https://dashboard.sinch.com
   • Settings > Access Keys: note Project ID, create Access Key (Key ID + Key Secret). Store Key Secret securely — shown only once.

2. Credential types by product

4. Plugin credentials (Antigravity)

   • Antigravity plugins do not prompt for credentials at install time. Export environment variables in your shell before starting agy:

     export CONVERSATION_PROJECT_ID="your-project-id"
     export CONVERSATION_KEY_ID="your-key-id"
     export CONVERSATION_KEY_SECRET="your-key-secret"
     export CONVERSATION_REGION="us"   # us | eu | br
     export CONVERSATION_APP_ID="your-app-id"

   • The bundled mcp_config.json passes ${CONVERSATION_*} through to the Build MCP. Restart agy after changing env vars.
