Opportunity Custom Field API

June 7th, 2021 - Automatically pause failing webhook subscriptions

We will automatically pause webhook subscriptions to which all event delivery fails for 3 days.

May 17th, 2021 - Custom Field ID Format

Going forward, all new Custom Fields will share a common ID prefix, cf_, instead of object type specific prefixes like lcf_ for Lead Custom Fields, and ccf_ for Contact Custom Fields.

Existing Custom Field IDs will not change, but be advised that we will soon allow existing Custom Fields to become Shared Custom Fields. This means a Shared Custom Field may have an ID prefix previously reserved for another object type. The ID prefix should not be used to infer the type of object associated with the Custom Field.

Apr 22th, 2021 - Shared Custom Fields

Several new endpoints let you create a single Custom Field, share it across multiple object types, and reorder all your Custom Fields:

Apr 13th, 2021 - Contact Filtering

A new endpoint that lets you find Contacts by an arbitrary set of filters.

Mar 31st, 2021 - Change to the Sequence API

When listing Sequence Subscriptions, it is now required to filter by sequence_id, lead_id or contact_id.

Jan 5th, 2021 - Changes to the Sequence API

Failed attempt at creation/update/deletion of a Sequence because of an issue with permissions will now return a 403 error instead of a 401 error.
Errors pertaining to Sequence Steps will no longer give you a deep nested error structure (e.g. {"field-errors": {"steps": {"errors": {...}}}}), but rather a simple high-level error (e.g. {"error": "The delay of a Sequence Step must not be larger than 365 days."}).

Oct 29th, 2020 - Microsoft Connected Accounts

It is now possible to connect Microsoft Accounts via OAuth for connecting Office 365 email. The new Connected Account type is documented in the Connected Accounts API.

Oct 9th, 2020 - Send As API

It is now possible to use the Send As feature through the API by using the Send As API. You can get which email accounts you can use to send emails through the Connected Accounts API.

Oct 3rd, 2020 - Active Calls on the Users Availability API

You can now use the Users Availability API to determine which users in your organization are currently on active phone calls in Close.

Sep 18th, 2020 - New URL for the Custom Field API

The recommended URL for the Custom Field API has changed from /custom_fields/*/ to /custom_field/*/. The latter form is more consistent with every other endpoint in our API. The old endpoint will continue to work, however, we recommend everybody to migrate to the new endpoint.

Aug 13th, 2020 - Groups

Groups are collection of Users. If you often use the same set of Users for filtering and reporting, you can now name them and use a Group in various places in Close.

Aug 7th, 2020 - Custom Activities Beta

We are beginning a limited beta test of a new Custom Activities feature. This feature will allow users to define arbitrary activity types specific to their workflow. The custom_activities, activity/custom and custom_fields/activity defined here are not yet accessible to all API users, and may change before the feature is launched.

Jun 30th, 2020 - Connected Accounts and clarification on field usage in integrations

You can now use the Connected Accounts endpoint to get information about any accounts you have connected in Settings > Connected Accounts. This is particularly useful in finding a sender_account_id when subscribing a contact to a sequence

Additionally, we have also added a clarification to the Fields section regarding the use of response fields in integrations. Non-custom fields that are returned by an endpoint that are not listed in our sample response should not be used in integrations, as they may change without warning.

May 19th, 2020 - HTTP/2 and Header Casing

We have started deploying new infrastructure that supports HTTP/2 connections. The HTTP/2 specification requires lowercase headers and HTTP/1.1 states header names are case insensitive. Therefore, we have updated our documentation to specify lowercase header names but will continue to support case insensitive headers in requests for HTTP/1.1 connections. Responses will have header names normalized to lowercase.

Apr 30th, 2020 - Custom Field Description

Custom Fields now have an optional description property, which is a longer description of the field that may be shown to users for context. This applies to both Lead and Contact Custom Fields.

Apr 6th, 2020 - Custom Fields on Contacts

Contacts can now have Custom Fields attached to them. A new API endpoint allows you to create Contact Custom Fields. Values for Contact Custom Fields can be attached to a Contact through the Contact API.

Dec 10th, 2019 - Introducing Pipelines

Pipelines are named and ordered groups of Opportunity Statuses. You can:

Create, update, and delete Pipelines via the Pipeline API.
Create Opportunity Statuses in a specific Pipeline via the Opportunity Status API.
Reorder Opportunity Statuses within a Pipeline and move them between Pipelines by sending a PUT to the Pipeline API.

With the introduction of Pipelines, we are deprecating the opportunity_statuses field in the Organizanization API and Me API. Use the pipelines field instead.

Nov 13th, 2019 - Deprecate old Activity Report endpoint

The new Activity Report endpoint was released May 8th, 2019 and should now be used to retrieve all Activitiy Report data. The older version of this endpoint is deprecated and will be removed in the future. The new version uses a POST to /report/activity/ and the old version uses a GET to /report/activity/{ORGANIZATION_ID}/.

Oct 31st, 2019 - Deprecate setting a status on an Opportunity via the `status` field

All new integrations should use the status_id field when POST/PUTting to the Opportunity API. Using a status label in the status field, albeit conveninent at first, could lead to broken integrations when users rename statuses in the UI.

Oct 12th, 2019 - Add new endpoint for Meeting activities

A new /activity/meeting/ endpoint has been added that allows you to interact with Close Meeting activities synced from Google Calendar. This feature is currently in beta, so the API is subject to change.

Aug 20th, 2019 - POST HTTP Status Code

For newer APIs, we return a 201 HTTP Status Code for POST requests when creating an entity. We also include a Location header with the URL for the new entity. Existing APIs will continue to return a 200 for POST requests.

Jul 2nd, 2019 - Add multiple value support to the bulk edit action

custom_field_values and custom_field_operation can now be used when creating bulk edit actions to replace, add, or remove multiple values at once on custom fields that accept multiple values.

Webhook subscriptions now support the extra_filter field which allows filtering of events based on field and value changes.

Apr. 25th, 2019 - Support for Multi-Select Custom Fields

"Choices" and "User" type Custom Fields can accept multiple values now:

Create a multi-value Custom Field by POSTing {"accepts_multiple_values": true} to the Lead Custom Field API.
Set multiple values for the Custom Field on a Lead by POSTing {"custom.lcf_xyz": ["Value 1", "Value 2", "Value 3"]} to the Lead API.

Contact API responses include country information for each phone number.
Phone Number API includes a list of countries the number can send SMS to.
SMS API includes country information for the local and remote phone number.

Jan. 25, 2019 - Event Log Fields

Events retrieved by non-admins will now include the data and previous_data fields for events not older than 1 hour. Older events will not include these fields as before.
