PUT request : Signature Does Not Match

Mamad

Hi all !

I'm having an issue when creating a post request and i don't understand how to solve it....

I send a POST request to an api that return a presigned url that i use a PUT request to upload images to these presigned, but every time I try the service can't get my images because the content of the urls is empty. When I went to look at one of the generated urls I saw this message and I think it's related to my problem of uploading images to these urls: 

<Error>

<Code>SignatureDoesNotMatch</Code>

<Message>The signature does not match the signature you provided. Check your keys and the signature method.</Message>

......

</Error>

Any Idea , how to solve this issue ?

Hey @Mamad without knowing the full context here, it looks like you need to have a signature for AWS to properly call the API. It seems you have the wrong signature in here. You may need to reference their documentation to see what is required.
