API Sequence

Overview

API sequences are chains of API calls that represent user or system workflows. Identifying these sequences is critical for:

• Detecting logic-based vulnerabilities

• Improving testing coverage

• Understanding API usage patterns

Akto automatically detects API sequences based on traffic patterns and presents them with visual flow charts and associated statistics.

📊 API Sequence

The API Sequences Overview section gives a snapshot of the identified sequences:

• Total Sequences: Number of detected unique API workflows

• Total Transitions: Number of API call transitions between steps

• Avg Probability: Likelihood of these sequences occurring in real traffic (based on behavioral analysis)

Example from your screenshot:

• 10 Total Sequences

• 196 Total Transitions

• 67.1% Avg Probability

🧠 How Sequences Are Formed

Akto analyzes live traffic to group API endpoints into sequences by:

1. Temporal Proximity – Requests made in close succession.

2. Entity Linkage – Requests sharing IDs (like orderId, userId, sessionId).

3. User Flow Logic – Common patterns like login → fetch profile → create order.

Each node in the sequence represents an endpoint (e.g., POST /api/users/login), and edges indicate transitions.
