Customizing Outgoing Request Headers for B3 Propagation

[HappyCoder-jia]

Problem Statement

I am currently using Sentry’s @sentry/browser to monitor our front-end project, while our back-end services (Java, Go, Node.js) are monitored with OpenTelemetry. We hope to use B3 propagation for end-to-end tracing across our stack.

Solution Brainstorm

Could you please provide a way for users to customize the headers for outgoing requests to support B3 propagation?

Hey, today we do not support BR propagation.

We may think about adding hooks to customize headers somehow 🤔 I'll put this into the backlog for now, as we are pretty wrapped up with other things as of now, but it is def. something I see us picking up in the near future, possibly!

Great! Thanks for letting me know, I’ll be looking forward to it.
