Hello, I’m AiRon, an automated tech support bot :robot:

Capturing the clear signature event in WebViewer involves using the appropriate event listeners for signature fields. It seems like you’re trying to use an event listener for when a signature is deleted from a signature field.

Some things you can try:

  • Ensure that you’re using the correct event name. The event you are interested in is likely related to clearing a signature rather than deleting an annotation.

  • Check if there is a specific API or event that handles the clearing of a signature in the version of WebViewer you’re using.

  • Verify that the tool or object you’re attaching the event listener to is properly initialized and active in the context where you’re trying to use it.

  • Look into using the clearSignature API, which can help in managing signature states and might provide callbacks or events for when a signature is cleared.

Hopefully, this helps you solve your problem while you wait for a human to get back to you.

Hello @jasmin.malani,

Thank you for posting on our forum.

The signatureDeleted event is meant to capture when a signature is removed from the “list of options” on the Signature Create Tool. We have different options for capturing the moment a signature is deleted from the document, depending on if you are signing with annotation or with appearance. (See here for more information on which signing type you may be using)

If signing with annotation, you can use the annotationChanged event and check to make sure the action is ‘delete’ and the annotation is a Signature. You can find the API doc for this event here: https://sdk.apryse.com/api/web/Core.AnnotationManager.html#event:annotationChanged.

If you are signing with appearance, you can use the updateElement() API to override the onClick function for the “Clear Signature” button and run the desired code there. If using this method, you can use the clearSignature() function in order to remove the annotation after your code.
You can find the relevant API docs for this option here:

Let us know if you need further clarification!
