Hello!

Ive asked ChatGPT to help me but it didnt give a viable solution

Ive done API calls before without any issues but this API service has gzip encoding  
I have put an "Accept-encoding" into the http request.

However all im getting back as expected is garbage.

Has anybody done this before? any help appreciated as usual 🙂

I guess you will need to unzip it to see the content ?

Take a look at node-red-contrib-gzip

Thanks for the reply!

the gzip node only compresses not uncompresses ?

ChatGPT talked about gunzip but that node doesnt exist (that I can see anyway)

Not quite true,

Passing a string, will compress said string, passing a buffer, will decompress said buffer.

So instead of returning a string from your request (assuming HTTP Request Node), get it to return a buffer, and pass that, the node will then treat it as a compressed buffer, and decompress it.
