An integral part of Zato, its scalable, service-oriented scheduler makes it is possible to execute high-level API integration processes as background tasks. The scheduler runs periodic jobs which in turn trigger services and services are what is used to integrate systems.

Using OAuth in API Integrations

September 19, 2022

OAuth is often employed in processes requiring permissions to be granted to frontend applications and end users. Yet, what we typically need in API systems integrations is a way to secure connections between the integration middleware and backend systems without a need for any ongoing human interactions. OAuth can be a good choice for that scenario and this article shows how it can be achieved.

Understanding API rate-limiting techniques

Dariusz Suchojad

August 11, 2022

Enabling rate-limiting in Zato means that access to Zato-based APIs can be throttled per endpoint, user or service - including options to make limits apply to specific IP addresses only - and if limits are exceeded within a selected period of time, the invocation will fail. Let’s check how to use it all.
