Recieve a video in API Connector

Need help

Hello everybody

I have a problem, trying to receive a video through the API Connector, it is giving an error

“The request signature we calculated does not match the signature you provided. Check your key and signing method.”

Even though you sent the credentials correctly

Please first set up your call on postman and then replicate the same in API connector

I did exactly that and it gave me the same error I get in Bubble

Can you share API docs
