Request body

Name Description

technologies

Array of technologies to filter by (no more than 50).

Name	Description
`slug` (required)	Technology slug, e.g. `hubspot-chat`. Refer to the full list of technologies (JSON).
`version`	Optional version number to target, e.g. `1.0.0`.
`operator`	Version number operator, one of `=` (exact match), `>=` (great than or equal to) or `<=` (lower than or equal to).

categories Array of category slugs to filter by (e.g. payment-processors). Refer to the full list of categories (JSON).

If a category includes more than 50 technologies, only the top 50 technologies will be selected.

keywords Array of keywords to filter by, e.g. fashion. Keywords must be alphanumeric (a-z0-9) and work best with English nouns. Prefix with not to exclude, e.g. not fashion.

languages Array of language codes (ISO 639-1) to filter, e.g. en-us.

countries Array of two-letter country codes (ISO 3166-2) to filter, e.g. US.

industries

Array of industries, e.g. Fashion & Apparel.

companySizes

Array of company sizes to filter, e.g. 5000 for 1,001-5,000 employees.

tlds Array of top-level domains to filter, e.g. .com.

matchCountryLanguage Filter by both country and language (true) or either (false).

matchTechnologies Operator for the technology filter, one of or (match any), and (match all) or not (match the first technology, exclude all others).

rootPath Only include websites that have the selected technology on the root path (typically the homepage).

subset Limit the number of results in the list per technology. Use subsetSlice to target high or low traffic websites.

subsetSlice Websites in the list are sorted in order of traffic. When a subset is specified, subsetSlice determines which section of the list the results should be taken from (i.e. top or bottom). Set to 0-4 for highest, high, medium, low and lowest traffic, respectively. Default is 0 for highest traffic.

This option has no effect when subset is equal to or larger than the total number of available results.

minAge Include results that were verified at least minAge months ago (0-11, default is 0).

maxAge Include results that were verified at most maxAge months ago (1-12, default is 3).

fromDate Only include websites that were discovered after a date (UNIX timestamp, e.g. 1620687647).

requiredSets Array of required field sets, e.g. email. See Fields.

subdomains Include or exclude subdomain in the results. One of include (default), exclude or merge.

By selecting merge, data for subdomains (such as languages and traffic) on a domain will be combined into a single result.

excludeNoTraffic Exclude websites that don't include traffic data (true or false (default)).

excludeMultilingual Exclude websites with content in more than one language (true or false (default)).

excludeListId ID of a list to use for exclusions, e.g. lst_abcdef. Any URLs that appear in this list will be excluded from the new list.

This function is recursive, i.e. if an excluded list excludes another list, both are excluded. Limited to ten lists or 500,000 websites.

baseListId ID of a list to use as a base, e.g. lst_abcdef. The results will be filtered to only include websites that are also in the base list.

sets Array of field sets to include in the results, e.g. email. See Fields.

callbackUrl Callback URL that's notified when the list is ready, e.g. https://yourdomain.com/wappalyzer.

format Output file format, one of csv (default) or json.

Initial response body

The initial response only includes the list ID and current status. Detailed fields such as totalCredits, sampleUrl, rows and setRows become available through the callback payload below or when fetching the list later.

Name	Description
`id`	The list's unique identifier.
`status`	List status. One of `Calculating`, `Ready`, `Failed`, `Insufficient` or `Complete`.

Callback response

Use a callback URL to continue your workflow as soon as a list is ready. List generation can take anywhere from a few seconds to a couple of hours depending on the query, so callbacks are the easiest way to avoid polling.

To verify that the request was made by Wappalyzer, enable callback signatures .

Example

Request

cURL

Node.js

Python

curl -X POST -H "Content-Type: application/json" -H "x-api-key: <your api key>" "https://api.wappalyzer.com/v2/lists/" -d '{ "technologies": [ { "slug": "shopify" } ] }'

Response

{
  "id": "lst_abcdef",
  "status": "Calculating"
}

Callback response

Your callback URL receives a POST request when the list is ready to price and finalize.

{
  "id": "lst_abcdef",
  "status": "Ready",
  "rows": {
    "shopify": 1000
  },
  "setRows": {
