# Entity Integration Record Not Found

## Overview

**403 - Forbidden**: This error occurs when the integration name provided does not match the specified entity integration.

    "success": false,
    "message": "Entity integration record not found."
}
```

***

## Common Causes and How to Resolve

1. **Missing Integration Name**:
   This error could occur due to missing the `sender` field in the request payload.

**How To Resolve**: Ensure the `sender` field is included in the payload for the specific api endpoint. You can find the api request specifications under our API reference page.

2. **Misspelled Integration Name**:
   The error could also occur if the `sender` field in the payload does not match the integration name configured in the system.  A misspelled integration name can result in the client ID not being recognized.

How To Resolve: Confirm the integration name (`sender` field) from the Payment Portal and ensure it is spelt correctly. You can access it under Workspace > API Keys.

## Best Practices

* **Validate All Required Fields**:
  * Always include `sender` field in the payload.
* **Double-Check Details**:
  * Verify the integration name is correct and matches what is configured in the system.
