My goal is to send an HTTP command to the Synology Chat bot.  
In Synology's cookbook, it is described as follows.

Place the JSON string after the payload application / x-www-form-urlencoded data parameter to the webhook url. Example:

```auto
POST https://DS_IP/webapi/entry.cgi?api=SYNO.Chat.External&XXXXX Content-Type: application/x-www-form-urlencoded payload=%7B%22text%22%3A%22This%20is%20a%20test.%22%7D

```

Below is an example of CURL:

```auto
curl -X POST \ --data-urlencode 'payload={"text": "This is a test"}' \ https://DS_IP/webapi/entry.cgi?api=SYNO.Chat.External&XXXXX

```

Now I've got it with the CURL as follows. This is how it works with CURL:

```auto

```

Now I thought to myself that it should actually work with the HTTP request. My attempts look like this. Unfortunately I haven't had any success with that yet.

```

The following error message then appears:

```auto
{"error":{"code":120,"errors":{"name":"payload","reason":"required"}},"success":false}

```

Since it works with the CURL command, it should also work with the HTTP command. Is anyone able to help me?

</div>

The error is clear .. it expects a `payload` in the posted data  
so in your Change node try :

![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/f/afb9ff93632c7ba3031e685be8292dc6499312a1.png)

a bit confusing because in NR `payload` is part of the msg sent .. but the POST needs a nested payload string for that property

</div>

Yes, that has fixed the error.  
But now I get another error:

```auto

{"error":{"code":404,"errors":"invalid token"},"success":false}

```

The token has not changed. It is the same as for the CURL flow. And there it works.  
So I guess the header should be urlencode?  
But it is also setup.

hi .. surely there must be something wrong with the token  
try to remove the `%22` from the beginning and end of your token= in the URL in the Http request node  
as these are the `"` character .. possibly not needed.

Hi, I have solved the problem. There was actually something wrong with the token. I generated and inserted a new one. Why ever that happened. Now it's working. I didn't need to remove the characters% 22. Thank you for your help.
