Selective Payload Logging for AI Gateway

Cloudflare AI Gateway has added a new cf-aig-collect-log-payload header that gives developers granular control over what data is persisted in logs.

What Changed

The new header allows you to:

• Keep logging enabled (default behavior with true): Store request and response bodies alongside metadata
• Skip payload storage (set to false): Log metadata only while omitting sensitive prompt and response content

What Gets Logged with false

When you disable payload storage, AI Gateway still captures valuable observability data:

• Token counts (input and output)
• Model name and provider
• HTTP status codes
• Request cost
• Request duration

Use Cases

This feature is particularly useful when:

• You need usage metrics and cost tracking but don't want to persist sensitive user queries
• Compliance requirements restrict storing prompt data
• You're working with PII or confidential information in requests

Implementation

Simply add the header to your API requests:

curl https://gateway.ai.cloudflare.com/v1/$ACCOUNT_ID/$GATEWAY_ID/openai/chat/completions \
  --header "cf-aig-collect-log-payload: false"
