Run a full lead search using structured filters. Pronto builds the underlying query for you, creates an asynchronous Search, and streams enriched leads to your webhook_url.

Overview

Use this endpoint when you want to extract leads matching a precise persona definition (titles + seniority + function + tenure + company filters + signals). Pronto:

Validates and translates your filters into a search URL.
Estimates the number of matching profiles.
Enqueues the search and returns immediately with a Search record.
Streams leads to your webhook.

Requirements

A valid Sales Navigator integration must be connected on the authenticated user — unless you pass live: false, which serves the search from Pronto’s people database and needs no integration.
webhook_url is required.
At least one filter or keyword must be provided.

Live vs. database mode

By default (live: true) the search runs in real time through LinkedIn Sales Navigator. Set live: false to serve the count, preview, and streamed results entirely from Pronto’s people database (Elasticsearch) instead — no Sales Navigator integration required. Relationship and signal filters only exist in LinkedIn’s graph, so they are rejected with 422 when live: false: connections_of_profile, relationship, follows_your_company, viewed_your_profile, with_shared_experiences, posted_on_linkedin, and past_colleague. Every other filter works in both modes. The same live flag is accepted by the preview endpoint.

Rate Limits

1 request per second per user.

Request body

Top-level options

Field	Type	Description
`webhook_url`	string (HTTPS URL)	Required. Where Pronto sends the enriched leads.
`live`	boolean	Data source. `true` (default) searches LinkedIn Sales Navigator; `false` searches Pronto’s people database with no integration required (see Live vs. database mode).
`name`	string	Friendly name. Defaults to `Lead search - API - <DD/MM/YYYY HH:MM>`.
`keyword`	string	Free-text keyword. Spell correction is automatically enabled when set.
`limit`	integer	Cap on enriched leads. Effective value is `min(limit, MAX_RESULTS_COUNT)`.
`streaming`	boolean	If `true`, leads are pushed to the webhook as they are scraped. Default `false`.
`scale`	boolean	If `true`, skips some data retrieval, for higher volume. Default `false`.
`custom`	object	Arbitrary JSON stored on the search and echoed back in every webhook payload.

`excluded_job_titles`	array of strings	Current titles to exclude (`CURRENT_TITLE` EXCLUDED).
`past_titles`	array of strings	Past titles to include (`PAST_TITLE` INCLUDED).
`excluded_past_titles`	array of strings	Past titles to exclude (`PAST_TITLE` EXCLUDED).

Location filters

Field	Type

Resolve region names to IDs with the Location IDs endpoint.

Industry filters

Field	Type

Each entry can be a plain LinkedIn organization id (string or integer) or an object with an id key (e.g. "1441", 1441, or { "id": "1441" }). Other shapes return 422.

Function & seniority

Field	Maps to	Valid IDs
`functions`	`FUNCTION`	`1` Accounting · `2` Administrative · `3` Arts and Design · `4` Business Development · `5` Community and Social Services · `6` Consulting · `7` Education · `8` Engineering · `9` Entrepreneurship · `10` Finance · `11` Healthcare Services · `12` Human Resources · `13` Information Technology · `14` Legal · `15` Marketing · `16` Media and Communication · `17` Military and Protective Services · `18` Operations · `19` Product Management · `20` Program and Project Management · `21` Purchasing · `22` Quality Assurance · `23` Real Estate · `24` Research · `25` Sales · `26` Customer Success and Support
`seniority_levels`	`SENIORITY_LEVEL`	`100` In Training · `110` Entry Level · `120` Senior · `130` Strategic · `200` Entry Level Manager · `210` Experienced Manager · `220` Director · `300` Vice President · `310` CXO · `320` Owner / Partner

Multiple IDs are combined with OR logic.

Tenure filters

LinkedIn uses bucketed IDs "1"–"8" for these filters:

Field	Maps to
`years_of_experience`	`YEARS_OF_EXPERIENCE`
`years_at_current_company`	`YEARS_AT_CURRENT_COMPANY`
`years_in_current_position`	`YEARS_IN_CURRENT_POSITION`

Bucket meanings (same scale for all three): "1" Less than 1 year · "2" 1 to 2 years · "3" 3 to 5 years · "4" 6 to 10 years · "5" More than 10 years. Buckets "6"–"8" are reserved by LinkedIn.

Company size & type

Field	Maps to	Valid values (same strings as account search)
`company_size`	`COMPANY_HEADCOUNT`	`1-10` · `11-50` · `51-200` · `201-500` · `501-1000` · `1001-5000` · `5001-10000` · `10001+` (en-dashes in requests are normalized to hyphens on the server)
`company_type`	`COMPANY_TYPE`	`C` Public Company · `E` Educational Institution · `G` Government Agency · `N` Non-Profit · `P` Privately Held · `S` Self-Employed · `X` Self-Owned

Lists & relationship

Field	Maps to	Value type
`included_account_lists`	`ACCOUNT_LIST` (INCLUDED)	array of account list IDs
`excluded_account_lists`	`ACCOUNT_LIST` (EXCLUDED)	array of account list IDs
`included_lead_lists`	`LEAD_LIST` (INCLUDED)	array of lead list IDs
`excluded_lead_lists`	`LEAD_LIST` (EXCLUDED)	array of lead list IDs
`relationship`	`RELATIONSHIP`	array of IDs: `F` 1st degree · `S` 2nd degree · `O` 3rd degree and beyond · `A` Group members
`recently_changed_jobs`	`RECENTLY_CHANGED_JOBS`	pass `["RPC"]` to enable
`connections_of_profile`	`CONNECTION_OF` (INCLUDED)	single LinkedIn profile URL — returns 1st-degree connections of that profile

connections_of_profile accepts any recognized LinkedIn profile URL:

https://www.linkedin.com/in/<handle>
https://www.linkedin.com/in/<internal-urn>
https://www.linkedin.com/sales/lead/<id>

The server resolves the URL to the target member’s internal id via LinkedIn before building the search. Returns 422 if the URL is malformed or can’t be resolved.

Boolean signal filters

These send a single fixed value when truthy. Pass true to apply.

Field	Maps to
`follows_your_company`	`FOLLOWS_YOUR_COMPANY` (id `CF`)
`viewed_your_profile`	`VIEW_YOUR_PROFILE` (id `VYP`)
`with_shared_experiences`	`WITH_SHARED_EXPERIENCES` (id `COMM`)
`posted_on_linkedin`	`POSTED_ON_LINKEDIN` (id `RPOL`)
`past_colleague`	`PAST_COLLEAGUE` (id `CL`)

Response

201 Created — returns immediately with the created Search:

{
  "message": {
    "id": "8e1dcba0-f0bb-4071-99fc-f18ba6559ccc",
    "search_name": "EU SaaS VPs of Sales",

    "created_at": "2026-05-04T12:34:56Z",
    "custom": { "hubspot_id": "134567" }
  }
}

Enriched leads are then POSTed to your webhook_url (one-shot at the end of the search, or per-batch when streaming: true).

Body

application/json

Lead advanced search parameters

webhook_url

string<uri>

required

HTTPS URL that will receive the enriched leads. Required.

Example:

"https://hooks.example.com/leads"

live

boolean

default:true

Data source toggle. true (default) runs the search live through LinkedIn Sales Navigator and requires a connected Sales Navigator integration. false serves the count, preview, and streamed results from Pronto's people database (Elasticsearch) instead, with no integration required. Relationship/signal filters that only exist in LinkedIn's graph are not supported with live: false and return 422: connections_of_profile, relationship, follows_your_company, viewed_your_profile, with_shared_experiences, posted_on_linkedin, and past_colleague. A non-boolean value returns 422.

Example:

true

name

string

Friendly name for the search. Defaults to Lead search - API - <DD/MM/YYYY HH:MM> if omitted.

Example:

"EU SaaS VPs of Sales"

keyword

string

Free-text keyword applied to the LinkedIn keywords query parameter. Spell correction is automatically enabled when a keyword is provided.

true

scale

boolean

default:false

When set to true, increases request volume by omitting the following fields: connections_count, headline, and vanity LinkedIn profile URL. You will still receive a LinkedIn profile URL, but it will use the user ID instead of the vanity URL (e.g., https://www.linkedin.com/in/mathieu-brun-picard/)
