Question

When running the go function part of this example https://techcommunity.microsoft.com/t5/apps-on-azure-blog/building-serverless-go-applications-with-azure-functions-custom/ba-p/3623617, receives only 1 message?!

Hello @guydillen, Thanks for reaching out.

The example which you have referred, uses an HTTP trigger, which means the Go function is invoked once per HTTP request. So, if you’re seeing only one message being processed, it’s expected as each HTTP request triggers the function once with a single payload.
If you’re trying to process multiple messages at once, you’d need to modify the client sending the request to include a batch of messages in a single request body and then update your Go handler to loop through and process them.
