Here's how I'd approach this problem:

I will implement callback verification for interactive anchors by signing outgoing payloads so client applications can verify they are authentic. I will ensure the verification process is secure, consistent, and easy for clients to validate.

I have experience working with backend security features and API integrations, and I can deliver a reliable implementation that strengthens trust between services.

Let me handle this for you.
