  1. Voice-only eSIM

Getting Started

The Voice-Only eSIM Service provides programmatic access to PressOne Africa Partner Program, enabling businesses to integrate voice-only eSIM functionality with phone number provisioning into their applications. This service allows partners to list available phone numbers, claim numbers for users, manage renewals, and retrieve user information.

Base URL#

The base URL for the Voice-Only eSIM Service API is:
https://api.pressone.co/
All API endpoints for this service are relative to this base URL.

Authentication#

To authenticate with the Voice-Only eSIM Service API, you will need to use API keys. PressOne Africa will provide you with an API key to communicate with the API endpoints on behalf of your organisation.
Authentication Method: Bearer Token
You must add the Authorization header to every request with your API key:

Example Request:
Important: Keep your API key secure and never expose it in client-side code or public repositories. Treat your API key as a sensitive credential.

Rate Limits#

There are no rate limits for using the PressOne Africa API. You can make requests as needed without worrying about rate limit restrictions.
