Best approach to determine signing status for each signer in a package

Hi Team,

We are using the OneSpan REST APIs to integrate OneSpan into our e-signature journey.

We have a requirement to display the signing status of each signer for a given package/transaction. In our setup, there is typically one signer per role.

I see the following possible approaches:

Option 1: Use the Signing Status API

I can call:

GET /api/packages/{packageId}/signingStatus?signer={signerId}

The signerId can be obtained from:

GET /api/packages/{packageId}

However, this would require an additional API call for each signer in the package.

Option 2: Derive Status from Document Approvals

Another approach is to iterate through the approvals array of each document returned by the package APIs and check whether the approval corresponding to a given role contains a signed timestamp.

My assumption is:

• If the approval for a role has a signed timestamp on all documents requiring that role's signature, then I can consider signing for that role as complete.
• Otherwise, the signer is still pending.

Can I reliably use this logic to determine signer completion status, or are there any scenarios where it might not be accurate ?

Option 3: Callbacks/Webhooks

We are aware of the callback/webhook option, but it is not suitable for our use case because we do not persist signer information in our database.

My primary question is regarding Option 2: Is it a reliable and supported way to determine the completion status of a signer, or would you recommend using the signing status API instead?

Thanks in advance for your guidance.
