The Cause IQ API enables you to access the industry-leading nonprofit data of Cause IQ directly in machine-readable formats. With the Cause IQ API, you can retrieve information on specific organizations and conduct programmatic searches to retrieve organizations that match specific criteria. The API is a REST API, returns JSON responses, authenticates with API keys via the Authorization header, and uses industry-standard HTTP response codes.

There are three API endpoints currently, created to help with the most common tasks of our customers:

1. Organization profile: Retrieve details on a specific organization with a GET request, providing the organization's EIN. By default, we provide the 20 most commonly-used fields in the response, including name, address, 501(c) type, NTEE code, fiscal year end, high-level financials, website URL, and phone number, among other fields. If you want more details, you can provide a comma-separated list of field names as a URL parameter, allowing you to retrieve any of more than 200 fields we have on organizations.
2. Organization search: Find multiple organizations that meet various criteria, using a GET request and user-supplied set of parameters. You can paginate on the results to see all the organizations that meet your criteria. The results provide a few of the most common fields; if you want detailed organization information, you can provide a comma-separated list of field names.
3. Match organizations: Used most commonly to quickly identify which organization corresponds to a web lead form submit, or to otherwise quickly match organization data to the legal entity and EIN, using a GET request and user-supplied set of parameters. You provide the endpoint with the fields you have available on an organization (e.g., name, domain, state) and the endpoint returns the top results that match those data points.

Cause IQ uses API keys to authenticate your requests, via the "Authorization" HTTP header. In your GET request, include the "Authorization" key with a value of "Token" and your API, with a whitespace between the two. For example:

Generate your API key within the "API" section of your Cause IQ Account Settings page. If you don't see an "API" section, contact Cause IQ support.

Unauthenticated responses will result in an HTTP 401 "Unauthorized" response. All requests must be made using HTTPS.

The Cause IQ API has usage limits that mirror your existing usage limits (if any) for exports and enrichments. In general, legacy Annual Usage-Based Subscription plans with the Data Enrichment Add-on have monthly usage limits, whereas newer Cause IQ Pro Subscription plans do not. If your plan has usage limits, each organization profile retrieved via the API counts as one record exported. As with exports, if you pull the same organization multiple times within a 30-day window, it only counts against your usage once. For the organization search API, search results are not currently rate limited. 

To see your limits, either go to your Cause IQ Dashboard, or check the headers of the API response, which will contain the following:

• x-rate-limit-limit: the rate limit ceiling for that given endpoint
• x-rate-limit-remaining: the number of requests left in your usage period
• x-rate-limit-reset: how many seconds until your usage period resets

If you go over your included usage, the response will be HTTP 429 "Too Many Requests". 

For all users of Cause IQ's API, we have these high-level limits in place:

• 20 paginations deep per search, up to the first 3,000 records (e.g., six pages deep at 500 records per search, 20 paginations deep at 150 records per search)
• 240 request per minute
• 25,000 records per day

The organization profile API allows you to retrieve information on a specific nonprofit organization using its EIN. Send a GET request to the following endpoint, replacing ":ein" with the organization's EIN (without any dashes, just a nine-digit string):

For example, here's what a request looks like in Python:

The response is a JSON representation of the organization, containing 20 of the most commonly-requested fields in Cause IQ on the organization. Here are the fields:

• ein: The EIN of the organization, without any dashes

Here's an example of the response object with the above default fields:

If you want to retrieve fields that are not provided above, simply add a fields query parameter with a comma-separated string of field names that you want to retrieve. The response will still include name and ein, but everything else will be the field values you requested (for a list of fields available, please get in touch with your Cause IQ contact). Here's what a Python request with custom fields looks like:

Here's what the response to the above request looks like:

Notice the percent_total attribute for the revenues_program_services and expenses_all_salaries_employee_benefits fields. This is the percent of total revenues and expenses, respectively for the two fields. Most non-total financial fields contain this percent of total metric.

The organization search API allows you to search and retrieve information on various organizations at once. For example, you can use this endpoint to find a specific organization if you don't have its EIN, or you can see all organizations that match a set of target market criteria. Just send a GET request to the following endpoint, adding query parameters for your search criteria:

For example, here's a Python request that searches for 501(c)(3) organizations in Montana that have more than $1 million in revenue:

This is equivalent to calling the following URL (with the authorization headers, of course):

Use request parameters to add filters, so you can narrow down to just the organizations you care about. You can also use the from parameter for pagination. The following query parameters are supported:

• keywords: Use this to search for an organization by name. It searches the names, past names, trade names, legal names, abbreviations, and other similar keywords associated with the organization
• 501_c_type: The specific IRS 501(c) subsection type, such as "501(c)(3)" or "501(c)(6)"
• website_domain: Filter organizations by the domain of their website, such as "nature.org". Only include the domain, no trailing slashes, no "https", no "www" or anything else like that. Subdomains are not supported
• ntee: The primary NTEE code of the organization, such as "C34". Note that if the NTEE code includes trailing zeroes, such as "C00", the search will use the NTEE code as a prefix (for example, "C30" would search all organizations with NTEE codes that start with "C3")
• cats_types: Each organization can have multiple types values, which describe at a high-level the kind of organization it is, such as professional_association, charities, or hq_parent. Contact Cause IQ for a list of values available.
• cats_issues: The issues that an organization works on or cares about, with each organization potentially having multiple issues, such as education, animals, and business_industry.
• cats_characteristics: A listing of general activities an organization undertakes or how it operates, such as memberships, lobbying, or pub78_tax_deductible.
• street: The street address of the organization, including partial matches
• city: The city where the organization resides. Cause IQ recommends using the metro search instead, when possible
• state: The two-digit capitalized state abbreviation, such as "VA"
• metro: The metropolitan statistical area CBSA code, such as "47900". This is provided in the address field in the Organization Profile API results
• county: The five-digit FIPS county code of the organization, such as "30063" for Missoula County, Montana.
• employees__gte and employees__lte: The number of employees at the organization. The "gte" and "lte" after the double underscore represent greater than or equal to the provided number of employees, or less than or equal to the provided number of employees, respectively
• revenues_total__gte and revenues_total__lte: The total revenues at the organization. The "gte" and "lte" after the double underscore represent greater than or equal to the provided revenues, or less than or equal to the provided revenues, respectively
• expenses_total__gte and expenses_total__lte: The total expenses incurred by the organization. The "gte" and "lte" after the double underscore represent greater than or equal to the provided expenses or less than or equal to the provided expenses, respectively
• assets_total__gte and assets_total__lte: The total amount of assets held by the organization. The "gte" and "lte" after the double underscore represent greater than or equal to the provided assets, or less than or equal to the provided assets, respectively
• liabilities_total__gte and liabilities_total__lte: The amount of liabilities owed by the organization. The "gte" and "lte" after the double underscore represent greater than or equal to the provided liabilities  or less than or equal to the provided liabilities, respectively
• employees_gte and employees_lte: The number of people employed by the organization (i.e., people filling out W-2s). The "gte" and "lte" after the double underscore represent greater than or equal to the provided number of employees or less than or equal to the provided number of employees, respectively
• last_updated__gte and last_updated__lte: The date we last updated an organization's information. This is for any update on an organization, even just minor tweaks. The "gte" and "lte" after the double underscore represent greater than or equal to the date provided or less than or equal to the date provided, respectively. Use YYYY-MM-DD string format for the dates, such as "2020-12-31".
• from: The 0-indexed start of the search results, used for paging. If you wanted to retrieve the next set of results, add a parameter "from" containing the value "20". You can retrieve up to the first 3,000 results, but beyond that we return an error message.
• limit: How many organization results are returned in the results response field. By default, 20 organizations are displayed. The maximum value is 500.
• fields: If you want to customize the fields you are retrieving, add a comma-separated string of field names that you want to retrieve.
  

The response is a JSON object contains:

• from: the 0-indexed start of the results, used for paging
• total: the total number of organizations that matched the search parameters
• results: the first 20 (or limit) organizations matching the provided parameters, sorted by best match, containing the name, ein, address, 501_c_type, form990_type, revenues_total, ntee, employees, and last_updated fields by default (see organization profile API section for definitions)

For example, here is a truncated response:

If you provide an invalid parameter, or an incorrect value for the parameter, the API will return a 400 status code, with additional information in the detail field in the JSON results.

The match organization API lets you find the organizations that most likely match random data points you have on an organization. The most common use case is when you have a lead form on the website where you want to match the submitted data to the corresponding organization, so that you can properly evaluate the lead. Send a GET request to the following endpoint:

For example, here's a Python request that searches for organizations that match a lead with the email "[email protected]" and state of "CA".

Use request parameters to add different fields to try to find the corresponding organization. Depending on the fields you provide, the match organizations endpoint will try a variety of queries and combine the fields in different ways to try to find the best organization matches. The following query parameters are supported:

• name: The name of the organization
• ein: The EIN of the organization
• city: The name of the city in which the organization is based
• state: The state in which the organization is based, either two-character abbreviation or state name spelled out
• zipcode: The five-digit zip code where the organization is based
• url: The organization's website URL
• email: The work email address of an employee at the organization. The algorithm extracts the domain from the email address, it does not match to an individual person

The response is a JSON array object contains containing name, ein, website_url, 501_c_type, address, other_names, ntee, and causeiq_url fields for up to five likely match organizations. For example, here is a response to the above query:

If you provide an invalid field, or don't include at least one of the name, ein, email, or url fields, the API will return a 4xx status code, with additional information in the detail field in the JSON results.

It can be helpful to know all the various options available for fields accessible with the API, whether pulling individual organization details or searching for specific types of organizations. Use the field definitions endpoint to see all options available for a given API-accessible field. Just send a GET request to the following endpoint, adding a field_name query parameter for the field you want the various values for:

For example, here's a Python request that provides all the options available for the cats_types field:

The follow fields are currently supported for identifying the correspond values for: ntee, 501_c_type, naics, metro, state, county, cats_types, cats_issues, cats_characteristics, and widget_types.

The response is simply an array / list containing the value and label for each of the options available for that field. For example:

If you provide an invalid field, the API will return a 400 status code.
