Http Request node - Making SAP API call

[weilies_chok]

Describe the problem/error/question

I am migrating my postman success sample to n8n

here is the postman’s CURL. I am pretty sure n8n was able to get Token as it’s passed in from previous node as input.

Error message:

NodeApiError: Bad request - please check your parameters

Hi @weilies_chok It doesn’t look like the SAP API is happy with that request - one thing I noticed here is that while in the cURL request you’re sending a GET, but in n8n you’re sending a POST - if you switch that around, does that fix this up?

it’s my bad. switching from POST to GET resolved the issue! thanks~~
