# Polling

As a dApp, you may want to check the status of a certain request in order to adapt your frontend. To achieve this, CKBull Signer API has two prepared endpoints to obtain the status of a request.

## Sign in request polling

A simple endpoint to obtain the status of a sign in request by its token.

{% openapi src="/files/IoEMLLlEMYecgfMTUZ2D" path="/api/sign-in-requests/{signInToken}/status" method="get" %}
[openapi-spec.json](https://4100684485-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPlB1oN5qXYGlSUWHxkql%2Fuploads%2Fgit-blob-cbbcae6fea374cebec1fa40b6477c93b3c9f8e5b%2Fopenapi-spec.json?alt=media)
{% endopenapi %}

As mentioned in [**Guides and concepts**](/guides-and-concepts/sign-in-request.md)**,** a sign in request can have the following status: **pending**, **expired**, **signed**, **declined** or **session expired.**

## Transaction request polling

A simple endpoint to obtain the status of a transaction request by its token.

{% openapi src="/files/IoEMLLlEMYecgfMTUZ2D" path="/api/transaction-request/{transactionToken}/status" method="get" %}
[openapi-spec.json](https://4100684485-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FPlB1oN5qXYGlSUWHxkql%2Fuploads%2Fgit-blob-cbbcae6fea374cebec1fa40b6477c93b3c9f8e5b%2Fopenapi-spec.json?alt=media)
{% endopenapi %}

As mentioned in [**Guides and concepts**](/guides-and-concepts/transaction-request.md)**,** a sign in request can have the following status: **pending**, **expired**, **signed**, **declined.**
