## TL;DR

Outreach rate-limits bulk prospect adds. Slow down, batch smaller, honor Retry-After, and resume where you left off.

## Error

```text
Outreach API error 429: rate limit exceeded
```

## Steps

1. Back off and honor Retry-After Expected: the throttle clears.
2. Reduce batch sizes Expected: fewer 429s.
3. Track progress so you can resume mid-list Expected: no prospect is added twice.
4. Re-run the remainder Expected: the list completes.

## When to use

- Outreach 429 on bulk add
- Too many requests too fast

## When not to use

- The limit is per-minute (then pace within the minute)
- 429s persist at low volume (then check for a ban)

## Tool compatibility

- Outreach API rate limits
- Prospect imports

## Variant phrasings

### outreach 429

Slow down, batch smaller, honor Retry-After.

### outreach rate limit exceeded

Same: pace the bulk add and resume.

## Why it happens

Bulk adds are bursty by nature. Outreach's limits are per-endpoint and agents blow through them.

## Edge cases

- Prospect creates also trigger workflows; watch for downstream throttles
- Idempotency matters: track what was added
