Authorization

To interact with Link2Pay’s APIs, every request must include your merchant credentials. This ensures that only verified merchants can initiate and manage payment requests.Required Parameters:

• merchantId – Your unique merchant account identifier.

• appId – Identifies the specific application or integration making the request.

• apiKey – A secure API key used to authenticate your request.

All API calls must be made over HTTPS to prevent interception and ensure data integrity. We recommend rotating API keys periodically and using environment variables to store them securely.
