You've got a CSV of leads or company data and need to push it into HubSpot without writing a script that searches, checks for existence, then creates or updates. This wraps the `hubspot objects upsert` CLI around a jq pipeline so you can match contacts by email or companies by domain in one pass per record. The dry run workflow is solid, the per-record JSON output lets you split successes from failures and retry just what broke, and it actually tells you about the five filter limit on OR searches instead of letting you discover it at 2am. If you're doing any kind of bulk CRM sync from external data, this is the pattern. Just lowercase your keys first.
npx -y skills add hubspot/agent-cli-skills --skill data-enrichment --agent claude-codeInstalls into .claude/skills of the current project.
Prereq: read bulk-operations/SKILL.md first — JSONL piping, dry-run/digest, history, and rate-limit hygiene live there. This skill is the upsert-by-natural-key workflow on top.
hubspot objects upsert --type X --id-property <natural-key> reads JSONL on stdin and creates-or-updates each row in one CLI call per record, keyed by a property (email for contacts, domain for companies). No race window, no branching. Do not loop search → empty? → create.
Per line in: {"id":"jane@example.com","properties":{"firstname":"Jane","jobtitle":"VP"}}
Per line out: {"id":"123","ok":true,"data":{...,"new":true|false}} or {"ok":false,"error":{...}}. Order matches input.
Reshape with jq, preview with --dry-run, then execute. Always lowercase the natural key — CRM match is exact. Confirm available property names with hubspot properties list --type contacts; never hard-code a list. See bulk-operations/resources/json-patterns.md for reshape idioms.
# CSV → JSONL (any tool); example using csvkit
csvjson external.csv | jq -c '.[]' > external.jsonl
# Preview
cat external.jsonl \
| jq -c '{id:(.email|ascii_downcase), properties:{firstname:.first, lastname:.last, jobtitle:.title, company:.company}}' \
| hubspot objects upsert --type contacts --id-property email --dry-run | head
# Execute (same pipeline, drop --dry-run, capture results)
cat external.jsonl \
| jq -c '{id:(.email|ascii_downcase), properties:{firstname:.first, lastname:.last, jobtitle:.title, company:.company}}' \
| hubspot objects upsert --type contacts --id-property email \
| tee /tmp/upsert.results.jsonl
Companies: swap --type companies --id-property domain and reshape with .domain|ascii_downcase as id.
Split with jq, inspect failure modes, retry just the failures after fixing the inputs:
jq -c 'select(.ok==true)' /tmp/upsert.results.jsonl > /tmp/upsert.ok.jsonl
jq -c 'select(.ok==false)' /tmp/upsert.results.jsonl > /tmp/upsert.failed.jsonl
jq -r '.error.status' /tmp/upsert.failed.jsonl | sort | uniq -c # status → count
jq -r '.data.new' /tmp/upsert.ok.jsonl | sort | uniq -c # created vs updated
429s: split the input and rerun smaller chunks (see bulk-operations rate-limit notes). 400s usually mean a bad property name or invalid enum value — fix the reshape, rerun the failed inputs.
upsert itself is non-destructive, but write-back can clobber populated fields. Always --dry-run first and spot-check. For bulk delete or overwrite of existing data, follow the dry-run → digest → confirm flow in bulk-operations/SKILL.md. Recovery: hubspot history --since 1h.
When you only want to read matches (no write-back), or the natural key isn't a CRM property, use repeated --filter flags — each flag is one OR group.
Verified cap: 5 OR groups per call. 6+ returns 400 too many filterGroups (count: N, max allowed: 5). Chunk 5 at a time:
# emails.txt: one lowercased email per line
xargs -n5 < emails.txt | while read -r e1 e2 e3 e4 e5; do
args=()
for e in "$e1" "$e2" "$e3" "$e4" "$e5"; do [ -n "$e" ] && args+=(--filter "email=$e"); done
hubspot objects search --type contacts "${args[@]}" --properties email,firstname,company
done > /tmp/matches.jsonl
jq -c '{id, properties:{lifecyclestage:"marketingqualifiedlead"}}' /tmp/matches.jsonl \
| hubspot objects update --type contacts --dry-run
For larger keyed enrichments, prefer upsert — one pipeline, no chunking math.
