Data Enrichment

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.

The core move: upsert, not search-then-create

hubspot objects upsert --type X --id-property 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.

CSV/JSONL → upsert stream

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.

Handle per-record OK / error output

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.

Destructive-op safety

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.

Match without upsert: OR-search → update

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  /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.
