Urgent ！My n8n.cloud instance is blocked from connecting to Webflow API

Help me Build my Workflow
1

Hello n8n Team,

My n8n cloud instance, glowwithwendyy.app.n8n.cloud, cannot connect to the Webflow API.

I have spent hours troubleshooting this and have confirmed the issue is with the n8n platform, not my credentials.

Here is the proof:

  1. I generate a new API token in Webflow with full permissions.

  2. When I enter this token into the Webflow API credential in n8n, it fails with the error “Couldn’t connect with these settings.”

  3. I take the EXACT SAME API token and test it using an external tool (ReqBin) to make a GET request to https://api.webflow.com/v2/sites.

  4. The external test is SUCCESSFUL. I receive a Status: 200 OK response from Webflow, and it returns my site data correctly.

This test proves that my API token is 100% valid and working.

The fact that the token works from an external tool but fails from my n8n instance is undeniable proof that my instance (glowwithwendyy.app.n8n.cloud) is experiencing a specific network issue that prevents it from communicating with api.webflow.com.

Please investigate the outbound connectivity of my instance. It is likely that the IP address of the server it’s running on has been blacklisted by Webflow or there is another network-level problem.

Thank you for your urgent attention to this platform issue.

Hey @Pak_Sing_Liu hope all is well.

Could you show how you are entering the API token into the Webflow API credentials in n8n?

Hi Jabbson, thank you for your prompt reply.

I tried to create a credential for webflow in my project, however it failed to logged in. Then I added a webflow node and logged in, somehow it connected to Webflow OAuth API. I did create a webflow before in my other workflow. But this is a new workflow so I created a new API. Please advise what should I do, thank you very much.

Hey @Pak_Sing_Liu

In the Webflow Node, can you see the credential you created under “Credential to connect with” at the top?

I can only see Webflow OAuth API

Have you tried to authenticate using the oAuth credentials
?

Thank you for your prompt reply.
We hope to stick with Webflow API credentials instead of OAuth, because the workflow is for me using only. And if using OAuth, I need to redesign the whole flow and it’s not necessary yet for this stage. So I sincerely ask for your help, to solve this Webflow API problem, because it is crucial for the flow. Thank you very much.

if the webflow node only accepts oauth, that is what you will have to use. If there is no option to choose the token when configuring the webflow node - not much can be done about it.
