Streaming data/file content in Azure APIM

Question

Streaming data/file content in Azure APIM

Nagashree Balasundaram 741

How do we achieve request and response data streaming in Azure APIM?
The requirement is to stream files to the backend application via Azure APIM and also retrieve them.
Currently we are using Apigee API management platform which provides streaming capabilities on both request and response side.

Hi @Nagashree Balasundaram Thanks for reaching out. The request and response data streaming can be achieved by using web sockets in Azure APIM.
For more information, please refer this document.
For importing Web socket API's in APIM please refer this blog.

Thanks for providing the information on websockets. We currently use http streaming options in Apigee for request and response content. We are not at liberty to have our consumers change to websockets implementation. Is there a way to do it via http - just like any other REST API call in APIM to handle large payloads?

@JananiRamesh-MSFT , thank you for your response.
Currently we were able to achieve this requirement by turning off request and response buffering on the forward request policy

Is this still the case? Seems a bit overkill to have to change the base URL just for two of my API endpoints
