HTTP compression headers are required starting from 1.6.2020.

You can of course start using the header right away.

Compression provides significant advantages: 1) Cheaper bandwidth costs 2) Faster requests

To use HTTP compression, please include “Accept-Encoding: gzip” header in your request. Most libraries do this automatically.

Attention! Uncompressed requests will be restricted starting from 24.3.2020. Requests from a single IP address will be restricted to a certain amount of requests per minute. When the request amount is exceeded subsequent requests will receive the HTTP response code 429.
