# 5.3  One-round signing with PDF with tags

When using a document that contains text tags, OKdokument API needs to know that it is needed to search them (_SO1_, _SO2_, _SO3_, _SO4_, _SO5_) and insert signature acrofields. This isn’t done automatically for all documents. It is required to set the document state to “tags” in the *filedata array.*

For this example, one-round signing there is no need to define which signature field should be available = they all are available.

But is really necessary to disable *sign anywhere* function (because the signature place is defined by tags/inserted signature acrofields) via parameter *rules:signAnywhere-false*, so that signer can sign only into pre-defined signature acrofields.
