On January 30, 2026, we deprecated the Bulgarian Lev (BGN) in favor of the Euro (EUR) following Bulgaria's entry into the Eurozone. If your integration uses BGN to create orders, update it to use currency: "EUR" instead.
We've added a new webhook event: PRODUCTS.UPDATED. This event is triggered whenever a product's skus are updated – for example, if a specific payout option supports a wider range of amounts.
We've added a new attribute to the product schema called subcategory. Merchant card products are now classified into more specific subcategories like electronics, fashion, or travel_and_hospitality. You can also filter the product list by one or more subcategories.
Previously, the funding sources endpoint only returned funding sources that were usable to pay for orders via the API. This led to questions from users like “Why doesn’t my credit card show up in the funding sources endpoint?”
On June 24, 2025, we will remove the Prepaid Mastercard product from our catalog. After this date, any API calls referencing its product ID (ZOGBCJB9TURC) will begin returning errors. If you use the Prepaid Mastercard product, you should replace it with the new Prepaid Virtual Visa (V4QZ00F554D3) to avoid disruptions.
On January 14, 2024, we’ll be updating our ACH product name to Bank Transfer (Product ID: ET0ZVETV5ILN). This new name better reflects the product’s functionality and offers clearer understanding for users.
We have introduced two new endpoints: POST api/v2/reports and GET api/v2/reports/{id}. These endpoints are designed to allow programmatic retrieval of your data on Tremendous.
On July 1st, 2024, we’ll be merging the Virtual Visa International product into the Virtual Visa (US) product to create a single Virtual Visa prepaid card. This product can be used in 213 countries, including the US, and has a 6-month expiration window.
We're updating some product IDs in the sandbox environment to make sure they match the IDs in production for all products. This will make migrating integrations from sandbox to production easier.
As part of the Fraud Prevention tool, we're now adding a new webhook event: REWARDS.FLAGGED. This event is triggered whenever a reward has been flagged for review and is pending manual review.
Please see our documentation on how to set up webhooks or to check the full list of supported events.
