The POST /v3/signature_requests/{signatureRequestId}/documents endpoint now accepts a flatten boolean parameter. When set to true, the uploaded PDF is flattened before storage, converting layers, form fields, and embedded elements into a single static layer. This resolves processing errors caused by complex or non-standard PDF structures. Learn more on our guide.

Custom Experiences are now scoped per environment. Production and Sandbox each have their own independent set of Custom Experiences:

• Quota is per environment. Your plan’s limit applies independently to Production and Sandbox. Usage in one does not reduce the other.
• A Custom Experience applies to a Signature Request only if both are in the same environment.
• Existing Custom Experiences have been replicated in Sandbox with the same IDs. No action is required.

📘

Custom Experiences are available on Pro (up to 2 per environment) and Scale (unlimited) plans.

Document Trust allows companies and compliance teams to analyse the authenticity of a document in order to detect document Fraud.

We leverage more than 600 detectors to give actionnable risk labels for your teams to take action. Risk labels range from : High, Medium, Low to Trusted and come with comprehensive indicators to help you understand the verdict.

To analyse any document's authenticity :

• Use the new : analysis_type[fraud_level]:'advanced'parameter on the Document Trust Analysis endpoint.

In addition to analyzing any document for authenticity, Document Trust enables you to run :

• Extraction
• Data consistency checks
• Document type check

On a wide list of selected documents, more details on supported documents can be found here

To get extraction results, data consistency checks and document type checks :

• Select a type among the ones we currently support
• use the analysis_type[extraction] : 'true' parameter to run an extraction.
• use the checksobject to match your data with the data extracted from the document.
