How this service works
Refresh a card's live balance and transactions from the issuer (rate-limited upstream: 1 per 5 min per card).
Output
Returns the card's current live balance and a list of recent transactions as retrieved directly from the card issuer, along with a timestamp indicating when the refresh was performed. Data reflects the issuer's state at the moment of the call, not a cached snapshot.
Example use cases
Verify balance before a large purchase
“Before I try to charge my card, can you refresh card xyz789 on Palmyr to make sure I'm seeing the real current balance, not a cached one?”
Reconcile unexpected transaction
“I think there's a charge I don't recognize — can you trigger a fresh sync on my Palmyr card card-456 so I can see the very latest transactions from the issuer?”
Automated card monitoring alert
“Every time my agent checks my Palmyr card card-001 spending, I want it to force a live refresh first so the balance and transaction list are always up to date from the issuer.”
Technical details
Endpoint
POSThttps://palmyr.ai/cards/:id/refreshWhen to prefer
Use this endpoint when you need guaranteed real-time card balance and transaction data directly from the issuer, rather than relying on potentially stale cached data. Prefer it when a user has just made a transaction and wants to verify it posted, or when a discrepancy is noticed between expected and displayed balances. Note the 5-minute per-card rate limit — avoid calling more frequently than necessary.
Side effects
- Rate limit hit — card was already refreshed within the last 5 minutes; returns 429 or equivalent throttle error
- Invalid or unknown card ID — returns 404 or similar not-found error
- Card issuer temporarily unavailable — upstream timeout or 5xx error propagated
- Unauthorized — caller does not own or have access to the specified card
- Card is inactive or closed — issuer returns no data
