Batch API limit now considers pending batch webhooks
We now allow a user to submit up to 500 pending API batches. For each completed batch, we send those results to each batch webhook that has been created. A user will not be able to create more API batches if there are 500 outstanding batch webhooks that have yet to complete. A 429 status code will be returned in this instance.
Previously, we did not have a limit on how many batch webhooks could be instantiated for a given user. This unbounded nature can have an impact on the performance of the API, which this new limit will help mitigate.

Added camelCase support to HandlebarsTransactional
In the past, our implementation of Handlebars did not support camelCase, so all variables had to be written using all lowercase letters or using snake_case. Using camelCase for variable names is now supported.

Fixed Rejection Denylist displayTransactional
We fixed an issue that was causing the Rejection Denylist page to appear as blank.
Expired entries were appearing on the Rejection Denylist page, which pushed out active entries and made the list appear empty. Now only active entries appear.

Added Stripe SCA payments pluginOpen Commerce
We’ve created a new Stripe plugin,
api-plugin-payments-stripe-sca, and we recommend that all users of the existing Stripe plugin migrate to it.
api-plugin-payments-stripeis now deprecated and will be supported until October 31, 2021. This release also affects the
example-storefrontrepository, which now includes components to support 3D Secure validation.
Thanks to contributor Janus Reith for his input.
The new plugin is designed to comply with the current Strong Customer Authentication (SCA) regulation, part of PSD2 regulation in Europe, which requires changes to how your European customers authenticate online payments.

Added new Allowlists series of endpointsTransactional
We’ve added a new series of Allowlists endpoints that are functionally identical to the Whitelists endpoints, but use new inclusive terminology instead.
In an effort to move towards using more inclusive terminology in our application, we’ve changed all instances of the terms “blacklist” and “whitelist” to “denylist” and “allowlist,” respectively. There may still be lingering uses of the old terminology in API responses or webhooks; please know that we are working on retiring all instances of those terms.

Cleaning up batch webhooks when deleting API keys or app connectionsMarketing
When deleting an API key or removing an authorized app connection, we will remove the batch webhooks created by that key or connection.
When a batch job completes, we send that response body to all created webhooks. Previously, these batch webhooks weren’t cleaned up when a user disconnected from an authorized app, or removed an API key.

Data changes with Apple Mail Privacy ProtectionMarketing, Transactional
Apple is launching Apple Mail Privacy Protection, which may change campaign reporting data. Check out our Apple Mail Privacy Protection Resources for more.
The Apple Mail Privacy Protection changes coming in iOS 15 will change Mailchimp’s email tracking for iOS users who opt in. Check our FAQ, but you may want to review how you use data and features related to opens and user location. If you surface this data in your integration, we recommend providing context on Apple’s changes.

Adding a limit to Batch WebhooksMarketing
We’ve added a limit to the number of batch webhooks you can create: going forward, you will not be able to exceed 20 batch webhooks for a given Mailchimp account. If you attempt to create a new batch webhook via the POST
/batch-webhooksendpoint and have already exceeded the limit, a 400 status code will be returned. In order to resolve this error, you will have to delete an existing batch webhook via the DELETE
Most users of the Batch Webhooks endpoint create fewer than 20 webhooks for their account. Allowing an unlimited number of webhooks for each account can have performance implications for the API.
