@rsto Thanks for sharing. Our app uses OAuth 1.0, and Twitter rate limits for OAuth 1 apps apply to individual users, not the Pipedream app as a whole. See the Rate limits and authentication method section of this doc.
They go on to say:
Users’ rate limits are shared across all apps that they have authorized and the Twitter application. For example, if a specific user likes 20 Tweets on the Twitter mobile application and likes 20 Tweets on a third-party application within a 24 hour period of time, the 40 requests would pull out of the same per user rate limit bucket.
Are you using any other applications that could be hitting Twitter’s user timeline API?
