Add a IP to list

I can’t add a IP to my list

curl -X POST "{redacted}/items" \
-H "X-Auth-Email: my_email" \
-H "X-Auth-Key: my_global_token" \
-H "Content-Type: application/json"\
--data '[{ip":"{redacted}"}]'


  "result": null,
  "success": false,
  "errors": [
      "code": 10026,
      "message": "filters.api.invalid_json"
  "messages": null
curl: (3) bad range specification in URL position 2:

For starters, that’s not a valid JSON syntax, so the error message would be accurate.

Plus, blocking a proxy address will be a bit pointless, as you will never get a request with such an address anyhow.

sandro, thanks for answer.
Please, answer the corect JSON syntax in my example.

Make sure you’ve created an list first.
Gather all the data you need.

--data '[{"ip":""}]' → you are missing starting double quote " and please use IP address in a CIDR notation.

Use below, replace YOUR_ACCOUNT_ID, YOUR_LIST_ID, [email protected] and YOUR_GLOBAL_API_KEY with your values:

curl -X POST "" \
     -H "X-Auth-Email: [email protected]" \
     -H "X-Auth-Key: YOUR_GLOBAL_API_KEY" \
     -H "Content-Type: application/json" \
     --data '[{"ip":""}]'

Successfull output response should be:

  "result": {
    "operation_id": "SOME_HASH"
  "success": true,
  "errors": [],
  "messages": []

You can also verify and re-check if the IP is added to your List by navigating to the Manage Account → Configurations → Lists.

Helpful article from the Cloudflare API docs:

Well, you need a valid JSON syntax. Use one of the available format checkers to verify that.

Plus, you really don’t need to block that address.

no, not work

curl: (3) bad range specification in URL position 2:

What command did you exactly run?

And why do you want to block that address? There’s no point.

I am missing the part where it is stated to block it? :thinking:
The List can be used to allow too, or not?

It’s best you post a screenshot.

Which is equally pointless. The whole address does not make sense here.

I just ran that very request and it worked just fine. Which brings us back to

The list is only for block some IP. This IP is just for example

Well, that IP you don’t need to block as mentioned. And any other IP address will still work.

The screenshot of the response is naturally not so useful and, of course, I meant what you are sending, because that’s where you make the mistake :wink:

And yes, redact the API key.

Auth-Key is ok. on GET I have a success result.
On POST, I have error

I did not ask you to use GET I asked you to post a screenshot.

Sorry, but we are going in circles.
