Webhooks and APIs (Application Programming Interfaces) are both methods for enabling communication and data exchange between Bevy and your systems, but they serve different purposes and operate in distinct ways.
Here are the key differences between webhooks and APIs:
| Webhooks | APIs | |
| Trigger vs. Request-Response | Webhooks are event-driven. They send data automatically to a predefined endpoint (URL) when a specific event occurs in the source system. The recipient system "listens" for incoming data and responds accordingly. Webhooks are initiated by Bevy (for example after a new user signs up), and the recipient system reacts to the data they receive. | APIs, on the other hand, are request-response-based. To access data or perform actions in Bevy, you make explicit requests to the API, specifying the desired endpoint, method, and parameters. The API responds to your request with the requested data or performs the action you specified. APIs are typically initiated by the consumer of the API. |
| Real-Time vs. Polling | Webhooks provide real-time data updates. When an event occurs, the data is sent (every 5 minutes) to the recipient, allowing for reactions to events without the need for polling or constant querying. | APIs require the consumer to actively make requests to retrieve or manipulate data. This often involves periodic polling or continuous querying to check for updates, which can lead to latency and increased server load. |
| "Push" vs. "Pull" | Webhooks "push" data to the recipient as soon as an event happens. The recipient doesn't need to actively request information; they receive updates automatically. | APIs require the consumer to actively make requests to retrieve or manipulate data. This typically involves periodic polling or continuous querying to check for updates, which can lead to latency, increased server load or rate-limiting issues. |
| Use Cases | Webhooks are ideal for scenarios where you want to receive real-time updates or notifications about specific events, such as new user sign-ups, payment confirmations, or data changes. They are commonly used for integrations, event-driven automation, and instant notifications. | APIs are more versatile and can be used for a wide range of purposes, including retrieving data and updating records. They can also be used to retrieve further information that is not coming directly in the webhook payload. APIs are typically used for building applications. |
In summary, webhooks are primarily used for real-time event-driven communication, where the source system pushes data to the recipient when specific events occur. APIs, on the other hand, are request-response mechanisms that allow consumers to actively retrieve and manipulate data from a remote system. The choice between webhooks and APIs depends on the specific use case and the need for real-time updates or periodic data retrieval.
