While Paythen does not currently have an API available, we do have a Zapier app in open beta you can access via this link. You can also read more about common Zapier workflows here.
Alternatively, you can achieve many advanced workflows by directly using the Stripe API which is comprehensive and well documented. When Paythen creates a customer or payment in your Stripe account, we try to provide comprehensive and structured meta-data with unique plan and customer identifiers in your Stripe account record.
If you'd like to be notified about the Paythen API when we have an update or it becomes available, let us know via the chat icon so we can add you to the list.
