Hi team,
I’m experiencing an issue with the built-in Perplexity node in n8n v1.107.4.
- When I try to connect my Perplexity API credentials, I get the error:
“Couldn’t connect with these settings. Bad request - please check your parameters.”
- I have verified that my API key is correct, has credits, and is copied directly from the Perplexity dashboard.
- I regenerated the API key and tried again, but the error persists.
- As a test, I used the HTTP Request node with the same API key (using the Authorization: Bearer header), and it works perfectly—so the key and network are not the issue.
It seems the problem is specific to the built-in Perplexity node or its credential handling in this version.
**Steps to reproduce:**
1. Go to Credentials > New > Perplexity API.
2. Paste a valid API key.
3. Try to connect/save.
**Expected:**
Credential should connect successfully.
**Actual:**
Get “Bad request - please check your parameters.”
Let me know if you need more details or logs!
Thanks,
Max

What is the error message (if any)?

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
Seems like its just the initial test that is failing but the node is actually working - I went ahead and tested it with some input data after setting up the perplexity node and then it worked!
same problem. Funny that it works in Personal project workflows and it doesn’t in Projects project. Same API Key. If I use a different it’s still the same.
I pasted the API key to the personal project last week and it worked. Today I tried to do something with Agents in another project, so maybe something died during this week and it cannot authenticate with perplexity api any more. I also culred the api to verify the key, and it returns output.
