The **payload-schema-error** occurs when the client receives screen data that does not conform to the schema defined in the Flow JSON layout. This issue prevents proper rendering of screens within the Flow.

## What Causes payload-schema-error?

This error typically happens due to:

1. **Mismatched Screen Data Format –** The data sent for a screen does not align with the schema defined in the Flow JSON.

2. **Incorrect Data Types or Missing Fields –** Some required fields are missing, or values are of an incorrect type.

3. **Flow JSON Schema Updates –** If the schema is updated, the sent payload must be adjusted accordingly.


## How to Fix the payload-schema-error

Follow these steps to resolve the issue:

### 1\. Verify the Flow JSON Schema

Check the Flow JSON file to understand the required schema for each screen. Ensure the structure, data types, and required fields are correctly defined.

### 2\. Ensure Compliance with Schema

Make sure the data sent for each screen matches the expected format.

Example of a correctly formatted JSON structure:

```
{
  "screen_id": "user_input_screen",
  "data": {
    "name": "John Doe",
    "email": "johndoe@example.com"
  }
}
```

### 3\. Fix Any Data Format Issues

Validate the payload before sending it. Ensure all required fields are included and properly formatted.

### 4\. Test and Debug

Use logging to capture errors related to payload structure. Test different scenarios to confirm the issue is resolved.

By following these steps, you can fix the payload-schema-error and ensure smooth execution of WhatsApp Flows. For more troubleshooting tips related to WhatsApp API, check out [heltar.com/blogs](http://heltar.com/blogs).
