Create or update your credentials with a third-party banking partner (provider). Banking as a Service clients need to partner with a provider such as Celcoin, BTG, JD Consultores, or Pay2All.
When you call this endpoint with your authentication key and secret, Pismo saves and encrypts the information you provide, then uses it to obtain an access token from the provider.
