I’m trying to add tags via the API, but I’m doing something wrong.
Here’s a good request made from the website:
```plaintext
PUT https://example.com/t/ueber-die-kategorie-organisation/74 HTTP/1.1
Host: example.com
Connection: keep-alive
Content-Length: 53
Accept: */*
Origin: https://example.com

tags%5B%5D=archiv-organisation&tags%5B%5D=archiv-2015
```
Here’s what I am trying to do:
```plaintext
PUT https://example.com/t/74?api_key=■■■■■■■■■■■■■■■■■■■■&api_username=system HTTP/1.1
host: example.com
content-type: application/x-www-form-urlencoded
content-length: 22
Connection: close
tags%5B%5D=archiv-2015
```
The server responds with `403 Forbidden`.
Does anyone see what I’m doing wrong?

Aha, I found it. As it turns out, the slug is required and must be correct for the API call to work.
That’s slightly annoying, but a solvable problem 🙂

It looks like you are JSON-Encoding the body, which won’t work. Your body should look like this:
```
tags%5B%5D=archiv-2015
```

Thank you, I realize now that I was trying to set the tags using a header
`Content-type: application/json` when it should be `Content-Type: application/x-www-form-urlencoded`
