Difference between API and Webhook.trigger

Hello Experts,
Can you help me to understand the difference between APIs and webhook triggers.

What kind of security cab be added if we use API and webhook as trigger.

Hi @ajay13chawda,
API - Its a collection of endpoints and 2way communication(can be also fire-and-forget).
Webhook - Its a single endpoint and only accepts request.

API - supports JSON WebToken, Oauth2
Webhook - None,Signature(https://docs.workato.com/developing-connectors/sdk/guides/building-triggers/securing-webhooks.html#sample-connector-hubspot-webhooks)

Hi @ajay13chawda ,
Here is the simple explanation:

Feature / Aspect API (HTTP Connector/Workato API Platform) Webhook Trigger (Real-time trigger)

Definition	A method to expose endpoints which clients can call on demand	A mechanism where external apps send data to Workato via a webhook URL
Triggering Mechanism	Pull-based – Initiated by the client sending requests	Push-based – Triggered by external systems when an event occurs
Usage Scenario	Ideal for retrieving or sending data when requested	Ideal for real-time notifications from 3rd party systems
Endpoint Exposure	API endpoints are published on the Workato API platform	Webhook URL is provided by Workato
Rate Limiting / Throttling	Supported (on API platform) to prevent misuse or overload	Not directly supported, but can be managed via queueing strategies

Webhook FAQ:
https://docs.workato.com/connectors/workato-webhooks/webhooks-faqs.html
Note: Webhook Triggers in Workato don't provide advanced security like OAuth or built-in HMAC validation.

API Security:
We have an option to use 🔐 OAuth 2.0, Basic Auth, API Key, Custom Headers.
