Hello @ben2,
For the cases when you donāt want to save the card you can use the userās token in the field payment source, without saving the token in the database. Basically, you donāt have to use the action ācreate a customerā if you donāt want to save data in the database.
The last issue can appear only if you use a source that isnāt related to any customer. We tested and on our side, this error doesnāt appear. Please make sure that when you create a customer in the field payment source you insert the token and as next action add āmake changesā and use it to save Customer ID and Source.
Regarding the issue related to āseller charge a customerā, we checked and the only case when this issue can appear is when the IDs are not right. Or the provided ID is related to and account that doesnāt have payment capability.
Best Regards,
Alex
