Introduction

The PressOne eSIM Partner API provides programmatic access to PressOne's Data eSIM Service, allowing businesses to discover packages, submit orders, deliver eSIMs to end users, and retrieve usage and installation instructions. The API is designed for partners and platforms integrating eSIM sales and management into their own applications.
The Data eSIM Service provides data-only or bundled data+voice+SMS eSIM plans for connectivity needs.
Use this API to enable your users to discover, purchase, and manage eSIMs in a production-ready environment. The API is focused on partner integrations (server-to-server); dashboard logins and user-facing authentication are handled separately.

Future versions#

PressOne may extend Partner API requests and responses with new attributes over time. Partners should design integrations to tolerate additional fields (forward-compatible). We aim to keep changes backward-compatible and will communicate breaking changes in advance when required.

API environments#

PressOne provides two separate environments with distinct base URLs and credentials:
EnvironmentBase URL example (Note: not real)Intended use
Sandboxhttps://sandbox.api.pressone.comDevelopment and QA testing. No real billing or provisioning is performed.
Productionhttps://api.pressone.comLive traffic: real transactions and provisioning. Use production credentials.
You will receive separate API credentials for each environment. Always validate your integration in Sandbox before switching to Production.
