I finished the API integration for the payments module. Ready for review.

Nice work. I'll pull it down after standup.

I noticed the webhook handler doesn't retry on 5xx errors. Should we add exponential backoff?

Good point. I'll add it with a max of 3 retries and 2s base delay.

Also make sure we log each retry attempt with the status code for debugging.

The Stripe test keys are rotated. New ones are in the vault.

I updated the env template with the new variable names.

Perfect. Let's sync after lunch to go over the full payment flow end to end.
