9501 input error (php based project)

[sdasdsad2]

Hi Team getting this issue, I am pretty sure the cert, key and creds are all right, if i enter wrong pass it says invalid cred thats how i tested. I thought it was datre in past at first.

How this project was setup for anyone in the future. I first set it up so I can access HelloWorld from this guide successfully using 

$client = new Client([

'base_uri' => $this->baseUrl,

'cert' => $this->cert,

'ssl_key' => $this->key,

'verify' => false, // Only for development. Use true in production.

'auth' => [$this->username, $this->password],

]);

then i get this error when using visa direct

{

"status": "error",

"message": "Multi Push Funds Transfer failed",

"error": "Client error: `POST https://sandbox.api.visa.com/visadirect/fundstransfer/v1/multipushfundstransactions` resulted in a `400 Bad Request` response:\n{\"responseStatus\":{\"code\":\"9501\",\"severity\":\"ERROR\",\"message\":\"Invalid input found, please correct the input data\",\"info (truncated...)\n",

Hey @sdasdsad2,

You can refer to Visa Developer Error Codes page.

The error message indicates that there is an invalid input in your request. To fix this, you need to ensure that the input data is correctly formatted and meets the expected criteria. Here are general steps to troubleshoot and fix the issue:

1. Verify Input Data: Ensure that all required fields are present and correctly formatted.
2. Check Data Types: Make sure the data types match the expected types (e.g., strings, numbers).
3. Validate Specific Fields: Verify that specific fields do not contain invalid characters or exceed length limits.
4. Consult API Documentation: Refer to the API documentation to understand the input requirements.

Here is an example of how you might correct the input data in a JSON request:

```json
{
"inputData": {
"field1": "validValue1",
"field2": 123,
"field3": "validValue2"
}
}
```

If you provide the specific input data that caused the error, I can help you pinpoint the exact issue and correct it.
