## TL;DR
HubSpot caps total API calls per day per portal; a bulk create that ignores the budget dies partway. Check the daily usage, queue the remainder, and resume the next day instead of retrying into the cap.

```text
hubspot batch create 429 daily api limit reached
```

## Use this when
- HubSpot returns 429 citing the daily limit.
- A bulk import stops halfway through with rate errors.
- The daily usage dashboard shows the quota consumed.

## Not for this skill when
- Burst or per-second limits, which clear in seconds with backoff.
- 401 token expiry.
- 403 scope errors on the app.

## Steps
1. Confirm the limit type: daily quota exhausted, not a per-second burst. Verify: the error or headers reference the daily allocation.
2. Checkpoint the job: record which batch items succeeded before the 429. Verify: you have an exact resume offset, not a guess.
3. Stop retrying today; retries against an exhausted daily quota all fail. Verify: zero API calls leave your system for the rest of the day.
4. Split the remaining work into daily-sized chunks that fit the quota with headroom. Verify: each chunk is under 80 percent of the daily limit.
5. Prefer batch endpoints over per-record calls to spend fewer calls per record. Verify: the call count per thousand records drops by an order of magnitude.

## Variant phrasings
### hubspot api daily limit exceeded 429
Common phrasing of the error.
### hubspot 429 too many requests daily
The daily-angle search.
### hubspot api call limit per day batch
The quota-angle search.

Compatibility: HubSpot API v3, all portals; daily limits vary by subscription tier.

## Why it happens
HubSpot meters API usage per portal per day to keep the platform stable. Bulk backfills that were sized for throughput instead of quota blow the daily budget, and every call after that fails until the window resets.

## Edge cases / pitfalls
- The reset is on HubSpot's clock, not yours; confirm the timezone before resuming.
- Burst and daily limits stack; pace for both, not just one.
- Private apps and OAuth apps share the portal quota; audit every integration's spend.
- Deleting data does not refund calls; plan imports once, not twice.
- The daily limit resets at midnight in the portal timezone; start bulk jobs just after the reset.
- Sandbox portals have their own quotas, so a job that works in dev can still 429 in production.
