| API |
Application Programming Interface. A set of rules and endpoints that allow applications to interact with a system programmatically. |
| APN |
Access Point Name. Defines how a device connects to a mobile data network and which services are available. |
| Authentication |
The process of verifying the identity of a client or application calling an API, usually by using tokens or credentials. |
| Authorization |
Determines what actions an authenticated client is allowed to perform within an API. |
| Bandwidth |
The maximum rate at which data can be transmitted over a network connection. |
| Catalogue |

| Connectivity |
The ability of a device or subscription to connect to the mobile network and exchange data. |
| Endpoint |
A specific operation within an API, identified by a URL and HTTP method. |
| Environment |
The context in which APIs are used, such as production or test. |
| HTTP Method |
Defines the type of action performed on an endpoint, such as GET, POST, PUT or DELETE. |
| ICCID |
ICCID stands for Integrated Circuit Card Identifier, a unique 18 to 22-digit serial number printed on the back of physical SIM cards or stored within eSIM profiles to identify the SIM hardware globally. It starts with "89" and is essential for activating services, switching carriers, and managing IoT devices. |
| IMSI |
International Mobile Subscriber Identity. A unique identifier associated with a SIM, used within the mobile network to identify a subscription. |
| Latency |
The time it takes for data to travel from a client to a server and back. |
| Lifecycle |
The current state of a subscription or SIM, such as active, suspended or terminated. |
| MSISDN |
Mobile Station International Subscriber Directory Number. The phone number of a mobile subscription, usually in international format (for example +31612345678). |
| Network |
The mobile infrastructure that provides connectivity for voice, data and messaging services. |
| OAuth |
An authorization framework commonly used to obtain access tokens for API calls. |
| Product |
A functional grouping of APIs that represent a specific service or capability. |
| Provisioning |
The process of activating, modifying or deactivating services on a subscription or SIM. |
| Rate limit |
A restriction on the number of API requests that can be made within a given time period. |
| Request |
A call made to an API endpoint, including method, headers and optional payload. |
| Response |
The data returned by an API endpoint after a request is processed. |
| Scope |
Defines the level of access granted to a token when calling an API. |
| SIM |
Subscriber Identity Module. Represents a mobile subscription that connects a device to the mobile network. |
| SIM swap |
The process of transferring a mobile subscription from one SIM card to another, often used to replace a lost or stolen SIM. |
| Subscription |
An agreement that enables access to mobile services such as data, voice or messaging. |
| Throughput |
The actual amount of data successfully transmitted over a network in a given time period. |
| Token |
A string used to authenticate API requests. Tokens are typically time-limited and must be included with each API call. |
| Usage |
Information about how a subscription is used, such as data consumption or activity metrics. |
| Versioning |
The practice of managing changes to APIs by exposing different versions over time. |
| Webhook |
A mechanism where an API sends data to a client automatically when a specific event occurs. |
