Add signature to signature set using iControl REST API

Yes, it is possible.

You can do it only for user-defined (not factory) signature set with "type": "manual".

Also, you can update only single signature-set by ID. Update operation is not supported for all signature-sets.

In addition, if you want to add signature to existing signatures (not replace all with new one), then you need to use additional appendnested=1 parameter in query string.

You request should look like next:

PATCH /mgmt/tm/asm/signature-sets/Mwgb4CF1d-FEFuioDxLD9w?appendnested=1 HTTP/1.1

Host: my.host.com

Content-Type: application/json

Content-Length: 115

{

  "signatures": [

    {

      "signatureId": 200101558

    }

  ],

  "type": "manual"

}

What RESTAPI request do you send?
