FAQ - PressOne eSIM Developer Platform

How do I authenticate with the API?

PressOne offers different authentication methods depending on the service:

Data eSIM Service:

Obtain your API key from your dashboard

Generate a JWT access token by calling POST /customer/v2/token with your API key

Include the JWT token in the Authorization header for all API requests: Bearer <your_token>

Tokens are valid for 24 hours and can be refreshed using POST /customer/v2/auth/refresh

Example Authentication Flow for Data eSIM:

Response:

{
  "data": {
    "token_type": "Bearer",
    "expires_in": 86400,
    "access_token": "eyJhbGciOiJIUzI1NiI..."
  },
  "meta": { "message": "success" }
}

Voice-Only eSIM Service:

PressOne Africa will provide you with an API key

Use the Bearer token authentication method

Add the "Authorization" header to every request: Authorization: Bearer YOUR_API_KEY
