Ingest

Every write endpoint: push events, create records, fix, remove, undo.

Events

One event: validated against its source pack, committed whole or refused whole naming the field.

  • Resolution, first hit wins: domain link (matches or creates) → source ids (match only) → universal ids → mintable anchor → explicit entityId → unresolved pool. A matching link beats entityId. Identity.
  • Three non-error outcomes: created, deduplicated: true (idempotency key already stored — keys are global, not per company), unresolvedContentId (nothing matched).
  • Static facts never go through ingest — attributes refuse with 422. Build.
  • Field-by-field walkthrough: Push events.

Batch differs from single ingest: no unresolved fallback (422 instead), no files[], one bad item rejects all with its 0-based index.

}

Resolve unresolved content to an entity

Body
{
  "unresolvedContentId": "01HXYZ123456789ABCDEFGH",
  "entityId": "01HXYZ123456789ABCDEFGI"
}
curl -s -X POST "$ACKDB_URL/entities/resolve" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "unresolvedContentId": "01HXYZ123456789ABCDEFGH", "entityId": "01HXYZ123456789ABCDEFGI" }'
Response · 200
{
  "data": {
    "entityId": "01HXYZ123456789ABCDEFGI",
    "contentId": "01HXYZ123456789ABCDEFGJ",
    "created": false,
    "identityLinksCreated": 1,
    "traitsWritten": 2
  }
}

On resolve, entityId: null always mints a new company — look the id up first with GET /entities/lookup and pass the match.

Fix

Merge two duplicate entities

Body
{
  "winnerId": "01HXYZ123456789ABCDEFGH",
  "loserId": "01HABCD123456789EFGHIJK"
}
curl -s -X POST "$ACKDB_URL/entities/merge" \

    "rawPayloadsTransferred": 42,
    "contentTransferred": 5,
    "filesTransferred": 0,
    "conversationsTransferred": 3
  }
}

Find and merge all duplicate entities

Body
{
  "apply": true
}
curl -s -X POST "$ACKDB_URL/entities/merge-duplicates" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \

Response · 200
{
  "data": {
    "message": "…",
    "duplicateGroups": 0,
    "applied": true
  }
}

Merge two persons

Parameters
personIdrequired—Person id (ULID = persons.person_id).
Body
{
  "loserId": "01HABCD123456789EFGHIJK",
  "winnerOverride": "…"
}
curl -s -X POST "$ACKDB_URL/persons/{personId}/merge" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "loserId": "01HABCD123456789EFGHIJK", "winnerOverride": "…" }'
Response · 200
{
  "data": "…"
}

Batch-merge the open candidates (dry-run by default)

Body
{
  "dryRun": true,
  "limit": 0
}
curl -s -X POST "$ACKDB_URL/persons/merge-duplicates" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "dryRun": true, "limit": 0 }'
Response · 200
{
  "data": "…"
}

Note

The two bulk merges arm differently: companies execute on { "apply": true }, persons on { "dryRun": false }. Humans are never merged automatically — conflicts wait in GET /persons/merge-candidates.

Declaratively set all values of one link type on a company

Parameters
refrequired—Entity id (ULID) or domain.
typerequired—The identity link type (e.g.
Body
{
  "values": [
    "123456789",
    "987654321"
  ]
}
curl -s -X PUT "$ACKDB_URL/entities/{ref}/links/{type}" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "values": [ "123456789", "987654321" ] }'

    "values": [
      "123456789",
      "987654321"
    ]
  }
}

Re-parent a mis-attached contact to the right company

Parameters
contactIdrequired—Contact id (ULID = contacts.contact_id) — the affiliation edge.
Body
{
  "entityId": "01J8ZE4X1M5Y6Z7A8B9C0D1E2F",
  "reason": "…"
}
curl -s -X POST "$ACKDB_URL/contacts/{contactId}/move" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "entityId": "01J8ZE4X1M5Y6Z7A8B9C0D1E2F", "reason": "…" }'
Response · 200
{
  "data": "…"
}

Re-point a contact to another person (the split primitive)

Parameters
contactIdrequired—Contact id (ULID = contacts.contact_id) — the affiliation edge.
Body
{
  "personId": "…"
}
curl -s -X PATCH "$ACKDB_URL/contacts/{contactId}" \
  -H "Authorization: Bearer $ACKDB_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "personId": "…" }'
Response · 200
{
  "data": "…"
}

domain is read-only on the links routes (422): it is the record's anchor, managed by resolution and merge. Ingest-time link conflicts never error — first writer wins and the event still lands.

Remove & undo

Ids only, by design — no filter-based mass delete. Every door takes dryRun, reason, actor.

Restore a deleted record

Parameters
idrequired—
curl -s -X POST "$ACKDB_URL/deletions/{id}/restore" \
  -H "Authorization: Bearer $ACKDB_API_KEY"

Permanently purge the archived copy (the tombstone stays)

Parameters
idrequired—
curl -s -X DELETE "$ACKDB_URL/deletions/{id}" \
  -H "Authorization: Bearer $ACKDB_API_KEY"

Lift the tombstone (allow re-creation)

Parameters
idrequired—
curl -s -X DELETE "$ACKDB_URL/deletions/{id}/tombstone" \
  -H "Authorization: Bearer $ACKDB_API_KEY"

A record delete freezes its ids as a tombstone: a re-syncing pipeline can't re-mint it — ingest drops or skips and says so in data.tombstoned; deliberate creates get 409 TOMBSTONED_IDENTIFIER. Delete and undo.
