V2 Bulk ContactInfo

Improves upon v1 by incorporating ContactOut's real-time work email finder. If no work email is found in ContactOut's database, the system attempts to guess and verify one in real-time.

This API enables users to retrieve contact details asynchronously through a background job process. Upon initiating the request, a job_id in standard UUID format is returned, which can be used to retrieve the results.
The user can then retrieve the results in 2 ways:
1. Callback URL: If an optional callback_url is provided in the request parameters, we send a POST request to that URL with the results once the job is complete.
2. Direct Request (Polling): Users can call the following endpoint at any time using the job_id obtained from the initial request: GET https://api.contactout.com/v2/people/linkedin/batch/{job_id}

Boolean Equations

Few input parameters mentioned in the table above can accept boolean equations as input. Check the "Accepts Boolean" column to know which input fields can accept boolean equations. You can use boolean equations to filter based on a specific criteria.

e.g. If you are looking for profiles who have the skills ReactJS and Python, but not Java, you can format the skills parameter as: { "skills": ["(ReactJS AND Python) NOT Java"] }. Always add brackets to ensure the boolean logic is applied correctly.

The same logic will apply for the rest of the mentioned paramters.

The supported boolean operators are:

Boolean operators must be capitalized. Lowercase and, or, and not are treated as part of the search phrase, not as operators. For example, Financial Planning and Analysis is searched as a single phrase.

For the industry parameter, prefix a value with NOT to exclude that industry (e.g. { "industry": ["NOT Computer Software", "Banking"] } returns profiles in Banking but not Computer Software). AND and OR are not supported for industry filters.

Response contains the meta information and the matching list of profiles. Each profile contains the information like title, headline, company details, experience, skills etc. It also lists the contact availability and contact information fields.

Parameter	Type	Description
contact_info	array	Returns an array containing contact information including email and phone numbers

Campaigns API

The Campaigns API lets you manage your email campaigns programmatically. You can list campaigns, retrieve a single campaign with its sequence steps and stats, add or remove recipients, and start or stop a campaign.

The Campaigns API must be enabled for your API token. If it is not enabled, requests return a 403 error. To unlock full access, please reach out to [email protected].

How to find the campaign_id

Most Campaigns API endpoints require a campaign_id. You can find it from:

The List Campaigns API — each campaign in the response includes its id.
The campaign URL in the web app — open a campaign and copy the campaign_id from the URL. It is the last segment of the URL, e.g. https://contactout.com/email/campaigns/{campaign_id}.

List Campaigns

Returns a paginated list of campaigns visible to your API user. The default personal scope returns only campaigns owned by the API user. The shared scope returns non-draft, non-archived campaigns owned by other users in the same company.
