I want to know how to send custom header (or metadata) using Python gRPC. I looked into documents and I couldn't find anything.
If you metadata has one key/value you can only use list(eg: [(key, value)]) ,If you metadata has Mult k/v you should use list(eg: [(key1, value1), (key2,value2)]) or tuple(eg: ((key1, value1), (key2,value2))
How to send custom header (metadata) with Python gRPC?
