HTTP Request: "ERROR: JSON parameter need to be an valid JSON"

[Jon]

Hey @kilter,

Is that what you sent with the header to check the auth?

Hey @Jon

I’m sorry, on the code before I’ve sent the webhook to n8n, not to webhook.site, but now I see what you mean.

Here’s the code from the webhook.site response:

Update:
I have tested the HTTP Request with a fixed number on the body code, and it finelly works!

Here it is:

{{
{
    "number": "55997692169",
    "text": "Top, APIGRATIS! Que massa.",
    "time_typing": 1
}
}}

But when I insert the json variantion of number from the previous node on the code, then I get the auth error:

{{
{
    "number": "$json.NUMERO",
    "text": "Top, APIGRATIS! Que massa.",
    "time_typing": 1
}
}}

Interesting there is no auth header there, Did you have the header set? Are you also setting the user-agent in n8n?

[kilter]

It worked!!

I’ve changed the body from JSON code to Parameters, here it is:

Ah nice, I guess you are now in charge of HTTP Request node support issues
