How to send span from Postman?

I’m using Grafana Cloud free plan. I’m trying to send span via HTTP to Tempo (based on example) but without luck, what is the correct URL which should be used for writing spans?


But GRPC is used usually, so it is not a simple plain json request. Check your Postman doc how to make GRPC request.

Adding to the answer above: Grafana Cloud Traces only supports OTLP gRPC for trace ingestion. You will need to send a gRPC request. The .proto are in here.
