# Getting Your Credentials

> How merchants receive and store API credentials securely.

> **This step is completed once per merchant.** A platform administrator registers your merchant account and provides API credentials.

To register a Merchant, please email [support@fexpayments.com](mailto:support@fexpayments.com) with the Merchant name and the point of contact email.

After registration, you will receive a JSON payload containing three values. **Store **`client_secret`** immediately** — it cannot be retrieved again. If lost, you must request a new one from your platform administrator.

```javascript theme={null}
{
  "merchant_id":   "a1b2c3d4-...",
  "client_id":     "merchant-a1b2c3d4-...",
  "client_secret": "xxxxxxxxxxxxxxxx",
  "note": "Store client_secret securely — it will not be shown again."
}
```

> **Best practice:** Store `client_secret` in a dedicated secrets manager (e.g. AWS Secrets Manager, HashiCorp Vault, 1Password Secrets Automation) rather than in environment variables or source code.
