Contacts

Manage contacts in your graph8 workspace — your first-party CRM data.

Contacts get into your workspace through several paths: saving results from the Search endpoints, importing from a CSV or CRM, creating manually via the API, or automatically during enrichment. Once a contact is in your workspace, these endpoints give you full read/write access at no credit cost.

List Contacts

GET /contacts

Returns a paginated list of contacts.

Query Parameters

Parameter	Type	Default	Description
`page`	integer	`1`	Page number (1-indexed)
`limit`	integer	`50`	Items per page (1-200)
`email`	string	—	Filter by work email (exact match)
`list_id`	integer	—	Filter by list membership
`name`	string	—	Filter by first or last name (partial match, case-insensitive)
`job_title`	string	—	Filter by job title (partial match, case-insensitive)
`seniority_level`	string	—	Filter by seniority level (exact match)
`company_name`	string	—	Filter by company name (partial match, case-insensitive)
`company_id`	integer	—	Filter by company ID
`country`	string	—	Filter by country (exact match)
`state`	string	—	Filter by state (exact match)
`city`	string	—	Filter by city (partial match, case-insensitive)
`job_department`	string	—	Filter by job department (partial match, case-insensitive)
`industry`	string	—	Filter by company industry (partial match, case-insensitive)
`include_custom_fields`	boolean	`false`	When `true`, each contact gains a `custom_fields` object of its custom column values keyed by column slug (`name` from `GET /fields`). Default `false` keeps the legacy shape and adds no extra query.

All filters are optional and can be combined. When multiple filters are provided, results must match all of them (AND logic).

Example

# Basic pagination
curl "https://be.graph8.com/api/v1/contacts?limit=10&page=1" \
  -H "Authorization: Bearer $API_KEY"

# Search by name and company
curl "https://be.graph8.com/api/v1/contacts?name=jane&company_name=acme" \

# Basic pagination
response = requests.get(
    f"{BASE_URL}/contacts",
    headers=HEADERS,
    params={"limit": 10, "page": 1}
)
contacts = response.json()

# Search by name and company
response = requests.get(

const response = await fetch(`${BASE_URL}/contacts?limit=10&page=1`, {
  headers: { Authorization: `Bearer ${API_KEY}` }
});
const contacts = await response.json();

// Search by name and company
const filtered = await fetch(
  `${BASE_URL}/contacts?name=jane&company_name=acme`,
  { headers: { Authorization: `Bearer ${API_KEY}` } }
);

// Filter by department and industry

Response

{
  "data": [
    {
      "id": 101,
      "first_name": "Jane",
      "last_name": "Doe",
      "work_email": "jane@acme.com",

  ],
  "pagination": {
    "page": 1,
    "limit": 50,
    "total": 1,
    "has_next": false
  }
}

When called with ?include_custom_fields=true, custom_fields is an object like {"udo_lead_score_1712000000": "92", "udo_persona_1712000111": "Champion"} (only set values appear; keys are the column slug). Rows with no custom values return {}.

curl "https://be.graph8.com/api/v1/contacts/columns" \

{
  "data": [
    {

      "is_global": true

Create Contact Column

POST /contacts/columns/create

Create a custom contact column. Optionally provision an enrichment waterfall pipeline in the same request so the column is immediately enrichable.

Request Body

Field	Type	Required	Description
`title`	string	Yes	Display name for the column
`data_type`	string	Yes	Column data type — currently only `"text"` is supported
`list_id`	integer	No	Scope the column to a specific list. Omit (or `null`) for a global column. Required when `enrichment` is provided (waterfall pipelines are list-scoped).
`created_by`	string	No	Email of the user creating the column
`enrichment`	object	No	Enrichment waterfall config — strongly recommended for enrichable columns. When supplied, a companion waterfall pipeline is provisioned in the same request so the UI Enrich button and `POST /enrichment/waterfall/enrich` work out-of-the-box. Without it the column exists but is not enrichable until you call `POST /enrichment/waterfall/configs`.

`enrichment` object

Field	Type	Description
`type`	string	Enrichment type — use `"waterfall"`
`providers`	array	Ordered list of provider slugs. Mutually exclusive with `steps`. Allowed values: `graph8`, `hunter`, `prospeo`, `dropcontact`, `icypeas`, `leadmagic`, `emaillistverify`, `apollo`, `lusha`, `rocketreach`.
`email_verification`	object	Optional email verification config (see below)

`enrichment.email_verification` object

Field	Type	Description
`provider`	string	Verification provider (e.g. `"zerobounce"`)
`enabled`	boolean	Whether verification is active
`use_system_credentials`	boolean	Use the platform’s credentials instead of your own
`accept_catchall`	boolean	Whether to accept catch-all addresses
`valid_statuses`	array	List of statuses to accept (e.g. `["valid"]`)
