Returns historic ERR (engagement rate by reach) metrics over days/weeks/months for any Telegram channel.
This endpoint provides historic data on engagement rate by reach metrics for any Telegram channel over days, weeks, or months. ERR is an engagement indicator that shows the percentage of subscribers that engage with a channel's post, adjusted by the number of subscribers. For example, if 100 users viewed a @bloomberg's post over the past 30 days, and @bloomberg has 1000 subscribers, the ERR will hover around 10%. By utilizing this endpoint, users can analyze the engagement of their channel over a period of time to gauge the overall effectiveness of their content.
