# Deploying the Verifier **What We Are Doing:** * Creating a Verifier service using One-Click Deployment. **Why:** The Verifier ensures that presented credentials are valid, coming from a trusted Issuer, and meet the required criteria. It automates cryptographic checks and provides a simple API. **Steps:** 1. In the One-Click Deployment platform, create a new Verifier. 2. Once active, note down necessary details. These variables can be found after clicking on the Verifier Details in the One-Click Deployment portal. * `VERIFIER_SERVICE_URL` (e.g., `https://your-verifier.evdi.app`) (the URL where the Verifier is hosted) * `VERIFIER_CLIENT_SECRET` (e.g., `your-verifier-secret`) (the secret used to authenticate requests to the Verifier) 3. Store these in your `.env` file so your application can access them securely: ``` VERIFIER_SERVICE_URL=https://your-verifier.evdi.app VERIFIER_CLIENT_SECRET=your-verifier-secret ``` After storing these details in .env, they will be easily accessible in your code using `process.env.VERIFIER_SERVICE_URL` and `process.env.VERIFIER_CLIENT_SECRET`, and you can use them in your CMD or terminal to interact with the Issuer service (to use it you muse run `source .env` in your terminal). Next, we will configure a verification flow in our backend. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
