What Can Invoke an OCI Function

In continuation to my previous blog (OIC vs OCI Functions vs PL/SQL) , here I have added some additional details about “What Can Invoke an OCI Function?” 

1.Oracle Integration Cloud (Most Common in Your Use Cases)

Oracle Integration Cloud calls OCI Functions via REST. . This is the cleanest and most supportable pattern for Fusion-centric integrations.

2.OCI Events Service (Object Storage, Compute, etc.)

OCI infrastructure can emit platform events:

• File created in Object Storage
• Resource state changes
• Streaming events

These events can invoke OCI Functions via event rules.

3.OCI API Gateway
API Gateway can expose:

• Public or private REST endpoints
• Secured APIs

Clients call API Gateway → API Gateway invokes OCI Function.
Common for:

• External integrations
• Webhooks
• Lightweight APIs

4.OCI Streaming Service
A stream consumer can:

• Pull messages
• Invoke OCI Function

Used in high-throughput architectures.
