# Release 3.11 developer changelog

## Release 3.11 · November 2026

### **Added**

- **Pay All flow in the widget.** Open the embeddable widget in the PAY\_ALL flow to take a user through connecting tax accounts, assigning a bank account and approving several tax payments in one session, inside your product. The widget reports the outcome of each item through approved, rejected, error and step\_changed events.
- **Connection API.** Create and track every tax authority connection through one API instead of one integration per authority, with tax identity verification endpoints and webhook events that report each stage.
- **Batch scheduling.** Submit many scheduled payments in one request. Batches are queued and processed item by item, and a batch.Processed.v1 webhook reports completion. Documented on docs.remitian.com.
- **IP allowlisting.** Restrict API access for your client application to approved IP ranges in the developer portal under **Developer tools \> Security**. The allowlist is enforced when tokens are issued and on every request.

### **Changed**

- Create or find a taxpayer, its tax entities and its tax accounts in one public API call, matched on natural keys so repeat calls do not create duplicates.
- Taxpayers can be filtered by email address, tax entities by TIN, and the widget can resolve a tax account by your own external ID.
- Stronger validation when creating tax payments and tax entities. Address is optional on tax entities; when provided for the US, region and a 5-digit ZIP code are required.
- Webhook payloads now include the firm object.

### **Fixed**

- Webhook payloads use camelCase keys consistently.
- The schedule.Deleted.v1 event is delivered when a tax payment is deleted.
