How to Decode Store API Tokens: Check JWT Expiry

When you integrate a platform's open API, tokens are usually JWTs. Decoding the payload to read the expiry lets you pre-empt those sudden "401 unauthorized" failures.

JWT decoding is purely local, so the token never leaves your device. Pair it with a Base64 encoder/decoder when debugging callbacks and tracking links.

Tokens are sensitive credentials - don't leave decoded results lying around on shared machines.
