Error

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
