Issue withh Bybit V5 API Signature Generation using Make.com, please help

Need Help with Bybit V5 API Signature Issue in Make.com

Hello Make community - I'm having some challenges generating a valid signature for the Bybit V5 API using Make.com. Every attempt results in this error:

{"retCode":10004,"retMsg":"Signature for this request is not valid.","result":{},"retExtInfo":{},"time":1736460157151}

Bybit Documentation Guidelines

According to the documentation, these are the requirements for signature generation:

"Basic steps:

  • timestamp + API key + (recv_window) + (queryString | jsonBodyString)
  • Use the HMAC_SHA256 or RSA_SHA256 algorithm to sign the string in step 1, and convert it to a hex string (HMAC_SHA256) / base64 (RSA_SHA256) to obtain the sign parameter.
  • Append the sign parameter to request header, and send the HTTP request. Note: the plain text for GET and POST requests is different."

Current Implementation

I've implemented the following:

  • Parameters are properly ordered alphabetically in both URL and signature string
  • Timestamp is retrieved from Bybit's time server with a +1000ms adjustment
  • API key has been verified to have read and write permissions
