Contacts

People you sell to. A contact can be linked to several accounts, and to leads, opportunities and activities.

A contact's links to accounts are ContactAccountRelations. Duplicate contacts can be merged into one.

What the API requires

A create needs first_name or last_name as well as owner_id, although the spec marks only owner_id as required. Without either name the API answers HTTP 422 with code 119, At least one of the fields [first_name, last_name] is required. (docs sandbox, 2026-10-14).

Method	Path	Operation
GET	`/entities/Contacts`	List contacts
POST	`/entities/Contacts`	Create a contact
GET	`/entities/Contacts/{id}`	Get a contact
PATCH	`/entities/Contacts/{id}`	Update a contact
DEL	`/entities/Contacts/{id}`	Delete a contact
POST	`/entities/Contacts/batch-modify`	Create or update contacts in a batch
POST	`/entities/Contacts/batch-delete`	Delete contacts in a batch
POST	`/entities/Contacts/batch-restore`	Restore deleted contacts
POST	`/entities/Contacts/merge`	Merge contacts

GET List contacts

Returns the contacts the API application can read, one page at a time. In the list envelope, total counts every match and page_info pages through them.

Query parameters

Name	Type	Description
`include-deleted`	boolean	Include soft-deleted records. Lists only; get-by-id refuses it.
`first`	integer	Page size. Default 30, maximum 100; a larger value is refused with HTTP 400, code 117.
`last`	integer	Return the last N records of the result; together with `first`, the last N of the first M. Maximum 100.
`before`	string	Cursor from `page_info.start_cursor`, to page backwards. URL-encode it.
`after`	string	Cursor from `page_info.end_cursor` of the previous page. URL-encode it: cursors are base64, and a raw + becomes a space.
`expand`	string	Related records to return inline instead of their URIs, comma-separated; dots reach nested relations, as in `account_relations.account`.
`order-by`	string	Fields to sort by, comma-separated. A leading - sorts descending, as in `-modified`; dotted paths sort by related fields.
`filter`	object	`filter[field]=value`. Separate several values with a raw comma (OR), as in `filter[name]=north,south`. Encode a comma that belongs to a value as %2C. URLSearchParams and Python requests encode every comma, so build the filter part of the query string yourself. Dotted paths filter on related records, as in `filter[owner.email]`. Encode a + in a value as %2B: query values are form-decoded, so a raw + becomes a space.
`filter-op`	object	`filter-op[field]=operator`, one per field: eq (the default), ieq, not-eq, not-ieq, contains, icontains, starts, istarts, ends, iends, gt, gte, lt, lte, between, null, not-null, empty and not-empty. null, not-null, empty and not-empty take no filter value; gt, gte, lt and lte take exactly one.
`load-only`	string	Fields to return, comma-separated (raw or encoded commas both work here); dots select nested fields, as in `owner.id`. All fields are returned without it. Lists only: get-by-id refuses it with HTTP 400, code 118.

Errors

Every error body has success: false, http_status, code, name and message. Branch on code: the status alone does not tell a missing permission from a bad parameter. All codes: error codes; how to handle them: Errors.

HTTP	When
400	Bad request: a bad or unknown parameter (codes 117, 118), a missing permission (code 50), conflicting data (code 2002) or any other API error. The REST API answers 400 where others answer 403 or 409; check `code`.
401	Not authenticated: missing or wrong credentials, a credential of another space, or an expired token (code 401, ERROR_UNAUTHORIZED).
404	No such record or entity (code 143 ERROR_NO_ENTITY, or 2006 ERROR_UNKNOWN_TYPE).
422	Validation failed (code 40000, with the failing fields) or a required parameter is missing (code 119). By default one failed item fails a whole batch and nothing is written.
429	Too many requests (code 182). Wait for the seconds in Retry-After, then retry.
500	Unexpected server error (code 1000, ERROR_UNKNOWN).
