ERR_RATE_LIMIT_HEADERS on Airtable: Rate limit headers missing. Root cause: The API response is missing the standard rate limit headers (X-RateLimit-Remaining, Retry-After, etc.) that the automation platform uses to throttle its own requests. This typically happens with non-standard API implementations or when a CDN/proxy strips response headers. Step 1: Confirm the headers are actually missing. In your automation tool or a REST client like Postman, make a direct API call to Airtable and inspect the raw response headers. Look for X-RateLimit-Limit, X-RateLimit-Remaining, and Retry-After. If they are absent, the issue is confirmed. Step 2: Switch to Airtable's official rate limit guidance. Airtable's REST API enforces 5 requests per second per base. Rather than relying on response headers to throttle, implement a fixed delay of 200ms between consecutive API calls in your integration. This is Airtable's own recommended approach as documented in their API reference. Step 3: Add exponential backoff on 429 responses. When Airtable returns HTTP 429, your integration should wait and retry. Start with a 1-second delay, then double it on each subsequent 429 (2s, 4s, 8s) up to a maximum of 30 seconds. After 5 retries without success, fail the request and log the error. Step 4: Batch requests where possible. Airtable's API supports creating or updating up to 10 records per request. If you are sending one record per request, consolidate into batches of 10. This reduces your total request count by 90% and makes the rate limit far less likely to be hit. Step 5: Monitor your request volume in Airtable's audit log. In Airtable, go to Account → Usage to see API call volume by base. If you are consistently near the limit, consider upgrading to a higher Airtable plan which provides higher rate limits, or restructuring your automation to reduce read operations by caching data locally.
