Remarks

The method parameter type can be one of the following:

By default messages received from the queue are expected to be Base64-encoded and are decoded before calling the function. This behavior can be changed by setting MessageEncoding. For example, to configure Azure Functions to perform no base64 encoding/decoding, specify the following in host.json.

"extensions": {
  "queues": {
    "messageEncoding": "none"
  }
}
