error 10209 - Error 10209 - PSE_SUBM_UNKNOWN_MISSING_COMPANY_TYPE

In PRODUCTION mode, if your Buyer gets an error message such as:

An error occurred during the payment request, please make sure that the posted parameters match the ones specified in the documentation.

It becomes impossible to make the payment and the transaction is definitively lost.

You will receive an e-mail notification containing the form that the gateway was unable to process and the value of the invalid field.

We invite you to check the following reason(s) to resolve the issue:

The vads_submerchant_company_type field is incorrect or missing

In Aggregator mode, the vads_submerchant_company_type field must be present and properly valued.

Please refer to the integration documentation for the payment method in question for accepted values.
