DocuSign Envelope File Size Limitations for REST API and Power Automate

While reviewing DocuSign integrations, I identified some important file size limitations that impact both the DocuSign eSignature REST API and the DocuSign Power Automate Connector.

REST API Limitations
The total envelope size (all documents combined) cannot exceed 200 MB.

Each document must be less than 50 MB.
For standard API uploads, individual document upload requests are subject to API size limits and large documents may require chunked upload methods.
Envelopes are limited to 130 unique documents.
Large or complex documents may fail during DocuSign's PDF conversion process, especially when conversion exceeds processing thresholds.

Power Automate Limitations

The DocuSign Power Automate connector has a known limitation where API gateway timeout errors may occur for documents larger than approximately 12 MB and/or envelopes containing more than 1,500 pages.
