# Resend webhook for a test charge (sandbox)

> Resends a webhook for a **test charge** with a simulated status.
Use this in sandbox to test your webhook handler without waiting for
real payment events.

Only works for test-mode charges (created with a sandbox API key).



## OpenAPI

````yaml /api-reference/openapi.yaml post /v1/charges/{id}/resend-webhook
openapi: 3.0.0

  title: FastPay API
  version: 1.0.0
  description: >-
    API for creating and managing payment charges.


    ## Authentication


    This API uses **Basic Authentication** for direct API access, such as
    creating charges.

    Use your API key as the username and an empty string as password.

    The header should be formatted as:


    `Authorization: Basic {base64(apiKey:)}`.


    For example:


    ```

    Authorization: Basic YWxleG91dG9uOiIi

    ```


    ## Webhooks


    FastPay sends webhooks to notify your application about charge status
    changes in real-time.

    Webhooks are sent via HTTP POST requests to your configured webhook
    endpoints.


    ### Webhook Events


    The following webhook events are available for charges:


    - `charge.created` - Sent when a new charge is created

    - `charge.pending` - Sent when a charge is pending payment

    - `charge.paid` - Sent when a charge is successfully paid

    - `charge.updated` - Sent when a charge is updated


    ### Webhook Payload Structure


    All webhook payloads follow this structure:


    ```json

    {
      "id": "webhook_event_id",
      "event": "charge.paid",
      "data": {
        // Complete charge object
      }
    }

    ```


    ### Webhook Delivery


    - Webhooks are sent via HTTP POST requests

    - Content-Type: `application/json`

    - Retry logic is implemented for failed deliveries

    - Webhook events are stored in the database for audit purposes

    - Delivery logs are maintained for debugging and monitoring


    ### Webhook Security


    - Webhooks are sent to pre-configured endpoints

    - Endpoints can be enabled/disabled per merchant

    - Event filtering is supported (only receive specific events)

    - Failed deliveries are retried with exponential backoff
