Receiving "SignatureDoesNotMatch" errors when using Spaces with Postman

API Object Storage

Very similar to the other 'SignatureDoesNotMatch' question but having issues with Postman,

So i'm trying to use postman to gain access to my files. I've set up the 'AccessKey' and 'SecretKey' pair within the API section in digital ocean but constantly getting '<Error>

anyone had any luck working through postman to access object spaces?

  • It's seams like DO spaces it's not very ready for production use. They say that supported only V2 signature version, but signing with V2 also does not work.

  • Hi there - I'm the product manager for Spaces. Thanks for letting us know that you ran into an issue.

    Would you be able to try again with a new access/secret key OR by regenerating an existing key?

    We in the last few days changed how key regeneration is done (we now regenerate the access key AND the secret) and using a new keypair (or regenerating an existing one again) is the likely fix for what you've reported.

    If for some reason that doesn't work, please let us know.

  • I've tried again with a new access/secret, but sadly still getting the same result. Has anyone managed to use 'put' with spaces via postman to create a new file?

Following Node.JS code is working for me. I suspect, we need to set up minimum 4 connection parameters.

var AWS = require('aws-sdk');
exports.getBuckets = async function(req, res)
var options = {
'endpoint' : '',
'accessKeyId' : 'XXXX',
'secretAccessKey' : 'YYY,
'region' : 'nyc3'
var s3 = new AWS.S3(options);
s3.listBuckets(function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
