Authentication

A Merchant API Key is required to access the Paylox API. This key is created and provided to you exclusively by the Paylox team.

How to Get an API Key?

1. Contact the Paylox team ([email protected])
2. Our team creates a merchant account for your business
3. A unique Merchant API Key is sent to you via email
4. Store this key in a secure location

tip

If your API Key needs to be renewed (e.g., in case of a security breach), contact [email protected]. Our team will revoke your current key and create a new one.

API Key Usage

The API Key is sent in the merchant_api_key field when creating a checkout session:

{
  "merchant_api_key": "fbd654ad-6448-4cbc-9780-5cdd3eadb677",
  "amount": 1000,
  ...
}

Security Warning

• Never use your API Key in frontend code
• Only send it in backend (server-side) requests
• If your API Key is compromised, immediately notify the Paylox support team
