Hi,

We’re planning to use the Streaming API with periodic reconnections every 30 minutes via scheduled AWS Lambda:

1. Connect with last saved timepoint
2. Read available events
3. Save timepoint and disconnect
4. Repeat in 30 minutes (~48 reconnections/day)

Question: Is this reconnection frequency acceptable, or does it risk rate limiting?

Your documentation mentions “repeatedly opening connections can lead to rate limiting,” but doesn’t define what “repeatedly” means.

Thanks!

Reposting the answer from support:

> The proposed Streaming API usage is acceptable, provided there are no more than 10 active connections per API key at any given time.
