# Retrieve Company & Certificates

## Retrieve Company & Certificates

Find company and certificates by name and match rate.

<mark style="color:green;">**`POST`**</mark> **`/company`**

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

* The API can only match one Certified Entity from IAFCertSearch per request.
* **Company Information Requirements**:
  * At least one of the two fields, `company_name` or `company_identifiers`, must be provided.
* **Match Rate Value**:
  * The default rate value is **94** when no `match_rate` is provided.
  * If an invalid (non-numeric) `match_rate` is submitted, it falls back to **30**.
  * The minimum accepted value is **30**; values below **30** are enforced to **30**.
  * Valid rate values range from **30** to **100**.
  * Any rate value exceeding **100** will automatically be capped at **100**.
* **Match Score Bands**:

  * The match score (0–100) is grouped into bands that determine the `match_type`:

  | Band      | Score Range | match\_type       |
  | --------- | ----------- | ----------------- |
  | Very High | 94 – 100    | `exactly_matched` |
  | High      | 80 – 93     | `loosely_matched` |
  | Medium    | 60 – 79     | `loosely_matched` |
  | Low       | 30 – 59     | `loosely_matched` |
  | Very Low  | 0 – 29      | not matched       |
* **Match Type**:
  * `match_type` is derived from the match score band:
    * **`exactly_matched`** — score 94–100 (Very High band). Credits are consumed and the verified data is saved to the company's default list.
    * **`loosely_matched`** — score 30–93 (High, Medium, or Low band). The result is returned for review but is **not** saved to the default list and does **not** consume credits.
* **Match Factors**:
  * `match_factors` is an object of booleans indicating which submitted fields contributed to the match. Each flag is `true` when that field matched the Certified Entity:
    * `company_name` — the submitted company name matched the Certified Entity name.
    * `company_english_name` — matched the Certified Entity's English name.
    * `company_trading_name` — matched the Certified Entity's trading name.
    * `company_identifiers` — one or more submitted identifiers matched.
    * `country` — the submitted country matched.
    * `city` — the submitted city matched.
* **Response Value:**
  * The API will return a single matched Certified Entity record with its Certificates.
