Error 429 (too many requests) in Power BI Embedding with Master User

[EduardD]

Hi Power BI Community,

We are using the "App Owns Data" scenario for embedding Power BI content, utilizing a Master User account for authentication. However, we've encountered the Error 429 (Too Many Requests) issue, which we suspect is due to multiple users connecting through the same Master User account simultaneously.

Would switching to Service Principal authentication resolve this issue? Are there any alternative approaches that would allow us to continue using the Master User setup without hitting throttling limits?

Thank you in advance for your help!

Hi @EduardD ,

Thanks for raising this question, and I agree with the point shared by @Akash_Varuna . It’s very likely that the 429 errors you’re encountering are a result of throttling on the Master User account.

As mentioned, switching to Service Principal authentication is the best long-term solution, especially when dealing with higher usage or concurrent embed requests. It offers several key advantages over the Master User approach:

• Higher API limits, which help prevent throttling

• Improved security (no need to store user credentials)

• Easier permission and workspace management

• Better suited for scalable, production-grade embedding scenarios

Hi @EduardD It is likely that 429 errors happen due to throttling on the Master User. Switching to Service Principal would be the best solution for high usage and avoids such limits.
