We have made updates to the Leads API :

1. We documented a new endpoint to improve the experience of using Leads:

• GET /leads/search - for searching leads by title, notes and/or custom fields

2. Three new query parameters are available in the GET /leads endpoint:

• filter_id - for retrieving leads by a filter
• owner_id - for retrieving leads by their owner
• sort - for sorting leads by a field name and a sorting mode

3. We added the lead_id body parameter to support linking leads to activities for the following Activities endpoints:

• POST /activities
• PUT /activities/{id}

4. leads is now documented as a possible value of the type parameter for these Filters endpoints:

• GET /filters
• POST /filters
