# Link Guarantor

> Link a guarantor to a tenant. The link is active right away. No invite is sent.
Both tenants must belong to your API key.

This is different from an application guarantor participant (`is_guarantor`).
This links two tenant accounts. An application guarantor is linked with the application instead.

  description: >
    ## Overview

    This is the SKOR Modular API v1. It provides access to tenant

    workflows, API keys, webhooks, document processing, identity

    verification, banking connectivity, and forensic analysis.


    ## Error Statuses


    The API uses standard HTTP status codes to indicate the success

    or failure of requests. Each error response provides guidance

    to help identify the issue and take corrective action.


    ### Success — `200 OK`

    The request was processed successfully and the expected response

    data is returned.


    ### Validation Error — `400 Bad Request`

    The request is invalid due to missing, malformed, or incorrect

    parameters.


    **Common causes:**

    - Required fields are missing from the request.

    - Invalid data formats or unsupported values are provided.

    - File size or payload limits are exceeded.


    **How to resolve:**

    - Verify all required parameters are present.

    - Ensure the request payload matches the documented schema.

    - Validate data formats and constraints before retrying.


    ### Unauthorized — `401 Unauthorized`

    Authentication failed or the provided token is missing or invalid.


    **Common causes:**

    - The `Authorization` header is missing.

    - An invalid or expired bearer token is provided.


    **How to resolve:**

    - Ensure the token is included in the request as an `Authorization: Bearer
    <token>` header.

    - Verify the token is valid and has not expired.

    - Generate a new token if required.


    ### Not Found — `404 Not Found`

    The requested resource does not exist or is not accessible.


    **Common causes:**

    - An invalid or non-existent resource identifier.

    - The resource has not been created or has been deleted.


    **How to resolve:**

    - Confirm the resource identifier is correct.

    - Ensure the resource exists before accessing it.


    ### Server Error — `500 Internal Server Error`

    An unexpected error occurred on the server while processing the request.


    **How to resolve:**

    - Retry the request after a short delay.

    - If the issue persists, **[contact us](mailto:info@skortorent.com)** with
    relevant request details.
