# Updated Swagger and API reference to match endpoint requirements

The following verbs and endpoints:

* ``[`POST /lists/{list_id}/preview-segment`](https://mailchimp.com/developer/api/marketing/list-preview-segment/preview-segment/)[``]\(/marketing/api/lists/create-member-note)[\`\`](/developer/marketing/api/lists/create-member-note)
* [`POST /lists/{list_id}/members/{subscriber_hash}/notes`](/developer/marketing/api/lists/create-member-note)

  [`](/marketing/api/lists/update-member-note)[`](/developer/marketing/api/lists/update-member-note)
* [`PATCH /lists/{list_id}/members/{subscriber_hash}/notes/{note_id}`](/developer/marketing/api/lists/update-member-note)

  [`](/marketing/api/lists/update-interest-category-interest)[`](/developer/marketing/api/lists/update-interest-category-interest)
* [`PATCH /lists/{list_id}/interest-categories/{interest_category_id}/interests/{interest_id}`](/developer/marketing/api/lists/update-interest-category-interest)

  [`](/marketing/api/lists/create-member-tag)[`](/developer/marketing/api/lists/create-member-tag)
* [`POST /lists/{list_id}/members/{subscriber_hash}/tags`](/developer/marketing/api/lists/create-member-tag)\`\`

Had a body parameter that wasn’t marked as required in our Swagger file, but was required for the API endpoint to work. These parameters are now marked as required.

This changed the method signature for the following methods in [our SDKs](/developer/tools):

* `createListMemberNote / create_list_member_note`
* `updateListMemberNote / update_list_member_note`
* `previewSegment / preview_segment`
* `updateInterestCategoryInterest / update_interest_category_interest`
* `updateListMemberTags / update_list_member_tags`

The parameters were incorrectly labeled. This caused confusion with some of our sample code, and was also factually incorrect.
