Line Credential are not working

Describe the issue/error/question

I think I did everything well by following the step in the doc

What is the error message (if any)?

{“code”:0,“message”:“HTTP status 400”,“stacktrace”:“Error: HTTP status 400\n at /app/code/node_modules/client-oauth2/src/client-oauth2.js:283:25\n at processTicksAndRejections (node:internal/process/task_queues:95:5)\n at /app/code/node_modules/n8n/src/credentials/oauth2Credential.api.ts:290:23”}

Share the output returned by the last node

Information on your n8n setup

  • n8n version:
  • Database you’re using (default: SQLite):
  • Running n8n with the execution process [own(default), main]:
  • Running n8n via [Docker, npm,, desktop app]:

Hi @JOduMonT, I am sorry to hear you’re having trouble.

I followed the steps outlined in the documentation and could connect to line as expected:



Is there a chance any of the values that need to be exchanged between n8n and line (callback URL, client ID, client Secret) contain a typo?

If not, can you confirm which version of n8n exactly you are using and if your n8n callback URL is publicly accessibly?

I reset my secret and did my cut and paste again and now it work :wink:

thank for your, as usual, quick reply!
