Method FindTokenAsync

Namespace

MailFathom.Application.Accounts

Assembly

MailFathom.Application.dll

FindTokenAsync(MailAccountId, CancellationToken)

Reads the stored refresh token for one account.

Task<MailboxRefreshToken?> FindTokenAsync(MailAccountId accountId, CancellationToken cancellationToken)

Parameters

accountId MailAccountId

The account the token acts for.

cancellationToken CancellationToken

Propagates caller cancellation.

Returns

Task<MailboxRefreshToken>

The token, which the caller owns and must dispose, or null when none is stored.

Remarks

An absent token is an ordinary answer rather than a failure: an account whose grant has never been stored is served from the refresh token its configuration references, which is what keeps a deployment that predates this store working unchanged.

Exceptions

CryptographicException

Thrown when the stored value does not open under the key it names — a row restored from another deployment, a value moved between accounts, or an altered ciphertext.
