# 5.4 Multi-round signing with PDF with tags

In multi-round signing with PDF with tags, with the registration of the first *signature request* it is necessary to define which signature acrofields should be available. This is done via parameter *allowedFields: SIGNATURE*, in our example value *_SO1_* (only *_SO1_* will be available for registered signature request) Note: as in example before do not forget to change the state of the document to “tags”.

```
{
    "signatureRequestId": "1d58a59e-e8f7-4d07-bb99-d3fa39cb58a8",
    "expirationTime": "1702288000000",
    "sendInfoURL": "http://api.okdokument/info",
    "resulturl": "https://okdokument.com/",
    "rules": {
        "signAnywhereEnabled": false
     },
    "allowedFields": {
        "SIGNATURE": "_SO1_"
    },
    "filedata": {
        "content": "xyz_JVBERi0xLjc==",
        "state": "tags"
    }
}
```

For the next round of signing, the same rules apply as for simple PDF apply. Portal has to:

- Register new *signatureRequestId* – if generated by OKdokument API it will be new random value, if pre-filled by Portal new *ID* must be used
- Reference to document *ID* – signed document from the first round of signing is stored in internal OKdokument API storage. Use document *ID* as a reference of the document (*filedata* with document content is not needed)
- *Change state* – after signing the document in the first round, the document changes the state to “signed”. It is needed to change the document state to “tosign” in order to sign the document in the next round of signing

Also, it should not be forgotten to change the available signature in *allowedFields* to *_SO2_* value (only *_SO2_* will be available for registered signature request)
