Hi everyone,
I’m trying to connect to Bybit’s API (v5 /position/list) using an HTTP Request node in n8n (self-hosted, version 1.89.2), but I keep getting a 401 Unauthorized - please check your credentials error.
Here’s a quick overview of my setup:
- I manually build the HMAC SHA256 signature using the
Cryptonode. - The
prehash_stringis generated like this:{{ $json.timestamp + $json.api_key + $json.recv_window + 'category=' + $json.category }} - Signature is computed with:
- Value:
{{ $json.prehash_string }} - Secret:
{{ $json.api_secret }} - Encoding: HEX
- Value:
- HTTP Request:
-
Method: GET
-
URL:
https://api.bybit.com/v5/position/list?category={{$json.category}} -
Headers:
X-BAPI-API-KEY:{{ $json.api_key }}X-BAPI-TIMESTAMP:{{ $json.timestamp }}X-BAPI-SIGN:{{ $json.signature }}X-BAPI-RECV-WINDOW:5000
-
Despite everything looking good, I still get a 401 response. I’ve double-checked the API key and secret… and retried with new keys… (I’ve deactivated my API keys… I can generate new ones if needed).
Any ideas what could be wrong? Is there something wrong with the prehash_string format or headers?
Thanks a lot for your help!
