This is an electronic money application available for prepaid payments which is used for various products and integrated services deployed on the ANICANA network.
The URI for the LEVICA REST API follows the format below:
${base_url}/v${version}/${resource}.
| Field | Description |
|---|---|
| base_url | URL of the server hosting the API. 'base_url' is the same for all APIs. |
| version | API version. |
| resource | Unique name assigned to each API. |
Please refer to each environment information page.
The LEVICA system exchanges data in a RESTful format.
- Request Authentication
To access resources of the system using the REST API, merchant authentication is required first. Authentication is performed using the merchant's clientId and clientSecret. The system provides a login REST API to execute the authentication. The clientId and clientSecret are passed to the system with this request. The system compares whether the clientId and clientSecret match the values in the database and checks them. If they match, the system creates an access token specific to the merchant, and these tokens are returned to the caller as a response to the authentication request. Access tokens contain the necessary merchant information, and these access tokens need to be stored. Therefore, when the system receives an access token with a REST API request, it can verify the merchant's authentication information.
