# Modify Crm List Memberships

`POST /integrations/crm/lists/memberships`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/integrations/crm/lists/memberships`
- Auth: HTTP bearer

Add and remove contacts from ONE CRM list, in a single call.

Both directions are applied in the same request, so this is not two calls
pretending to be one - and repeating the same body is idempotent on the
provider side. Membership drives who receives the customer's CRM-side
marketing, which is why it is admin-gated.

## Query parameters

- `connection_id` string, required

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Request body

- ModifyListMembershipsRequest: Add and/or remove contacts from one CRM list, in a single call. Both lists are applied in the same request, so this is not two calls pretending to be one - and a retry with the same body is idempotent on the provider side.
  - `list_id` string, required: The CRM's list id.
  - `add_contact_ids` string[]
  - `remove_contact_ids` string[]

## Response `200`

Successful Response

- ApiResponseCrmPayload
  - `data` CrmPayload, required: One CRM record, or one provider response. Open-shaped ON PURPOSE. These bodies carry whatever the provider returned, the field set differs between HubSpot, Salesforce, Pipedrive and SugarCRM, and it grows every time one of them ships something. Pinning it would drop whatever a provider reported that this contract had not caught up on - which on a CRM surface means silently hiding the customer's own data from them.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
