Verification Users - API Developer Guide

API Integration

Getting Started

There are several ways you can get started with the IAFCertSearch Verification Users API.

Prerequisites

Before you can start using the API, you need to do the following:

Create/Activate an IAF CertSearch account.
- Step-by-Step Signup Process
Generating an API Key
- To generate the API Key, go to API Settings from the left navigation. Under the Generate API Key section, click the Generate API Key button.
Make sure you have curl installed on your machine.

Authentication

Authorization Header

To authenticate, add an x-http-authorization header to your API request that contains an API Key.

API Keys

IAF CertSearch’s Verification Users API supports the use of API Keys. API Keys allow you to use another method of authentication separate from your account username and password. API Keys add an additional layer of security for your account and can be assigned to limit which areas of your account can be accessed. API Keys can be generated in your account. To use keys, you must set a plain text header named “x-http-authorization” with the contents of the header being “(API Key)” where (API Key) is your API Secret Key.

Example Header

GET {API_URL}/sample-endpoint HTTP/1.1
x-http-authorization: Your.API.Key-HERE

curl -X "GET" "{API_URL}/sample-endpoint" -H "x-http-authorization: Your.API.Key-HERE" -H "Content-Type: application/json"

For more information about the API URL, see the requests page.

Requests

Making a Request

API URL

To access the API URL, log in to your IAF CertSearch account and go to the page.

All requests must be made over HTTPS. The API does not support HTTP.

Authorization Header

You must provide an authorization header as described in .

HTTP Verbs

GET Retrieve a resource or group of resources
POST Create a new resource
PUT Update an existing resource
DELETE Delete an existing resource
OPTIONS View allowed verbs against a specific resource

Accept Header

The API provides JSON responses. It doesn’t currently require the accept header, but might in the future. If not set, the API will use application/json.

Arrays of Data

When you send an array of data in a GET request, you will include the parameter multiple times on the URL. The parameter name does not require brackets.

Formatting Your Request

Request Body

When submitting data to a resource via POST or PUT, you must submit your payload in JSON.

Pagination

Some GET resources allow for retrieval of information in batches. We will provide the query parameters in the resource documentation when applicable.

When requesting multiple items, we will default the request limit to 20 items. You can specify a different limit using the limit parameter when you need to. The maximum value for the limit parameter that we accept is 100.

Below you can see an example of an API request which retrieves the first 100 records as specified by the limit=100 and offset=0 parameters.

To retrieve the next batch of records, increment the offset parameter by 1.

Successful Requests

Responses

Content-Type Header

All responses are returned in JSON format. We specify this by sending the Content-Type header.

Status Codes

Below is a table containing descriptions of the various status codes we currently support against various resources.

Response Code

Description

Pagination

When a request is made with a pagination query, the meta data is included in the response to allow for easy traversal of previous, current, first, and last page of the data set.

Errors

Sometimes your API call will generate an error. Here you will find additional information about what to expect if you don’t format your request properly, or we fail to properly process your request.

Response Codes

Status Code Description

400 Bad request
401 Requires authentication
403 Forbidden
404 Not Found
405 Method Not Allowed
406 Missing Accept header. For example: Accept: application/json
429 Too many requests/Rate limit exceeded
500 Internal server error

Failed Requests

The general format guidelines are displayed when the accompanying status code is returned.

GET {API_URL}/sample-endpoint HTTP/1.1

HTTP/1.1 404 BAD REQUEST
Content-Type: application/json

Verification APIs

Verification API

Verify Company

POST /verify-company

Fields that are marked with an asterisk (*) are mandatory.

The API can only accommodate one company information per request.
Company Information Requirements:

- If both fields are provided, company_identifiers will take precedence in the certified entity matching algorithm.
Match Rate Value:
- The default rate value is set to 100.
- The minimum acceptable rate value is 80, regardless of whether a lower threshold is specified.
- Valid rate values range from 80 to 100, in increments of 5.
- Any rate value exceeding 100 will automatically be capped at 100.
Response value:
- The API will return a single matched company record with its certificates.
