DocuSign Envelope File Size Limitations for REST API and Power Automate

Question

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.

The total size of all documents in an envelope must not exceed 200 MB.
The maximum document size is less than 50 MB. For REST API uploads, the request-size limit is lower than the per-document limit: use base64 for smaller files, binary transfer for files above 25 MB but below 32 MB, and chunked uploads for larger files.
An envelope can contain up to 130 unique documents.
The page limits are 2,000 pages per document and 5,000 pages per envelope.
Docusign converts uploaded files to PDF. Large or complex source files may fail if conversion exceeds the processing threshold. Converting to PDF before upload or splitting the file can help.

For the Docusign Power Automate connector, API gateway timeout failures may occur when documents exceed approximately 12 MB and/or the envelope exceeds 1,500 pages. This is a connector limitation and can occur even when the envelope remains within the REST API limits.

Recommended options for larger workflows are to reduce or split the documents, keep the flow below the Power Automate thresholds, or use a direct REST API integration when chunked upload support is required.
