It returns reusable `form_fields_per_document` and `form_field_groups` definitions together with structured warnings and errors. * The `expires_at` parameter now supports `/signature_request/send_with_template`, `/signature_request/create_embedded_with_template`, `/signature_request/bulk_send_with_template`, and `/signature_request/bulk_create_embedded_with_template`. `/signature_request/update` can also add an expiration to a request that did not previously have one. See the [Signature Request Expiration Date guide](https://developers.hellosign.com/api/manual-reference-pages/expiration). ## Fixes * Requests that use `grouped_signers` now reject duplicate email addresses, preventing ambiguous recipient assignments. Integrations that previously reused an address within `grouped_signers` must now provide unique email addresses. * Fixed embedded `close` events after a signer completes, declines, or reassigns a request. See the [HelloSign Embedded SDK](https://github.com/hellosign/hellosign-embedded). * Fixed signer attachment processing so file-size and page-count limits are consistently enforced. * Fixed embedded signing so the original signer no longer receives a completion email after reassigning a request and the replacement signer completes it. ## Announcements * Read [Signing made simpler: What's new with Dropbox Sign](https://sign.dropbox.com/blog/whats-new-with-dropbox-sign) for an overview of recent improvements, including AI-powered documentation search, redesigned mobile signing, Salesforce SMS workflows, and expanded data residency. ## September 3, 2026 ## API documentation * Added callback payload schemas and examples for the seven Fax API v3 events. ## August 19, 2026 ## API documentation * Added `ignore_text_tags_extraction_errors` to the API reference for supported signature request, template, and unclaimed draft workflows.
