We’re writing to let you know that from August 11, 2026, we’ll update our Issuing API specification to enforce the Entity ID requirement for create a cardholder requests, and the card product identifier requirement for issue a card requests.
Our API reference already requires these fields and most customers already send them. We’re making this change to maintain a consistent customer experience.
Create a cardholder and issue a card requests without this information will fail after August 11.
What’s changing?
- For create a cardholder, we’ll validate to check if the entity_id is present
- For issue a card, we’ll validate to check if the card_product_id is present
If a request fails due to this data not being provided, we’ll return a 422 response (entity_id_required, or card_product_id_required), and you’ll need to retry the request.
