## TL;DR

Define a card product (spending limits, expiration, usage methods), create the user (who gets a GPA account), then create the card referencing both tokens.

## Fix

1. Define a card product (spending limits, expiration, usage methods), create the user (who gets a GPA account), then create the card referencing both tokens.
   Expected: you can confirm this matches your situation.

- The symptom matches: card product, user, webhook signature verification.

## When NOT to use

## Why it happens

Issuing a card needs three objects: a card product, a user, and the card itself.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
