# GET DID Nonce

With the exception of DID registration (`did_register`), each HTTP request to the IDIN server must contain a request nonce (`"nonce"`). A nonce is bound to a DID address and starts at one for the first HTTP request after the DID registration. The DID nonce then increases by one for every request, and as a result it counts to the total number of requests that the DID has made.

The current nonce of a DID (`<did_address>`) can be obtained with a GET request.

{% hint style="danger" %}
If the input nonce (`"nonce"`) in a HTTP request does not match the current nonce of the given DID, the request will be rejected by the IDIN server.
{% endhint %}
