Hello Team,

I would like to ask if it is possible to add custom validation logic before account creation in Kill Bill. If so, could you please advise on the recommended approach or extension points to achieve this?

Best regards,

Ahmed

Hi Ahmed,

Could you please provide more details OR examples of what custom validation are you looking for.

Hi Karan,

For example, I need to add a validation step to verify whether the externalKey already exists in the third-party system and, based on that, determine whether it should be created.

Thanks for your support.

Best regards,
Ahmed

Hi Ahmed,

What is your flow of account creation, like are you using API to pull the details and create account in KB? The validation would lie before the KB api is invoked. On KB side, it just checks if external key is mentioned, if not, then it uses the account ID as external key.
