Contacts - Clarky Docs

Bulk upsert contacts

method

POST

POST /api/v1/contacts/upsert

Insert or update up to 200 contacts in a single request. Each input contact is matched against existing contacts in this order:

Primary phone number (if no email match)

If a match is found, the existing contact is updated. If not, a new contact is created.

Body fields

Field	Type	Required	Description
`bot_id`	string	Yes	Agent to own newly created contacts
`contacts`	array	Yes	Array of contact objects (same fields as Create). Max 200.

Example

curl https://clarky.ai/api/v1/contacts/upsert \
  -H "Authorization: Bearer ck_live_example" \
  -H "Content-Type: application/json" \
  -d '{
    "bot_id": "b_01HDEF",
    "contacts": [
      {
        "first_name": "Ada",
        "emails": [{ "email": "ada@example.com", "is_primary": true }]
      },
      {
        "first_name": "Grace",
        "emails": [{ "email": "grace@example.com", "is_primary": true }]
      }
    ]
  }'

Response

{
  "data": {
    "created": [
      {
        "id": "c_01HNEW1...",
        "first_name": "Grace",
        "emails": [{ "email": "grace@example.com", "is_primary": true }]
      }
    ],
    "updated": [
      {
        "id": "c_01HXYZ...",
        "first_name": "Ada",
        "emails": [{ "email": "ada@example.com", "is_primary": true }]
      }
    ],
    "errors": []
  }
}

created

Contact[]

Contacts that were newly inserted.

updated

Contact[]

Contacts that matched an existing record and were updated.

errors

array

Per-row failures as { index, message }. The numeric index is the position of the failing item in the input contacts array. The rest of the batch still succeeds.

Upsert counts as a single write against your rate limit regardless of how many contacts are in the batch — much more efficient than a loop of POST /contacts calls.
