First off, welcome to the Pipedream community. Happy to have you!
The Twitter app on Pipedream is unique in that all Pipedream workflows share the same rate limiting, this is because technically it’s the same app in Twitter’s perspective.
You can separate your usage from other Pipedream users by registering your own Twitter app and using the Pipedream Twitter Developer App instead of the Twitter app integration.
This will separate your requests “pool” from the rest of the Pipedream user base.
