When using API keys, Iterable requires them to be provided as an HTTP request header. However, certain legacy projects have exceptions that still allow API keys to be provided in the query string or request body.
As of November 10, 2025, API calls that provide the key in the query string or request body will be subject to stricter rate limiting.
To avoid being impacted by this change, modify your application code to use API keys as HTTP request headers instead of using the query string or request body.
