Documenso Common Errors
Overview
Quick-reference troubleshooting guide for Documenso API errors. Covers authentication, document lifecycle, field validation, file upload, webhook, and SDK-specific issues with concrete solutions.
Prerequisites
Working Documenso integration (see documenso-install-auth)
Access to application logs
API key available
HTTP Error Reference
Status
Error
Cause
Solution
401
Unauthorized
Invalid, expired, or missing API key
Regenerate key in dashboard; verify Authorization: Bearer <key> header
API key starts with api_ (personal) or is team-scoped
No trailing whitespace or newline in env var
Key hasn't been revoked in dashboard
Scenario 2: 403 — Personal Key on Team Resources
// Error: "Forbidden" when accessing team documents// Personal API keys can only access YOUR documents// Fix: generate a team API key from Team Settings > API Tokensconst client = newDocumenso({
apiKey: process.env.DOCUMENSO_TEAM_API_KEY!, // Team-scoped key
});
Scenario 3: Cannot Modify Sent Document (400)
// Error: trying to add fields to a PENDING document// Documents can only be modified in DRAFT status// Check status firstconst doc = await client.documents.getV0(documentId);
if (doc.status !== "DRAFT") {
thrownewError(`Cannot modify document in ${doc.status} status. Cancel first or create new.`);
}
// To re-edit: cancel the sent document, modify, then re-send// Note: cancelling notifies all recipients
Scenario 4: Invalid Field Position (400)
// Error: field coordinates out of range// pageX and pageY are PERCENTAGE-based (0-100), not pixel-based// WRONG: pixel coordinatesawait client.documentsFields.createV0(docId, {
recipientId, type: "SIGNATURE",
pageNumber: 1,
pageX: 200, // Invalid: > 100pageY: 600, // Invalid: > 100pageWidth: 150, pageHeight: 50,
});
// CORRECT: percentage coordinatesawait client.documentsFields.createV0(docId, {
recipientId, type: "SIGNATURE",
pageNumber: 1,
pageX: 10, // 10% from left edgepageY: 80, // 80% from top edgepageWidth: 30, // 30% of page widthpageHeight: 5, // 5% of page height
});
Scenario 5: File Upload Errors (413)
// Error: PDF too large for upload// Cloud plans have per-document size limits// Solution 1: Compress PDF before uploadimport { PDFDocument } from"pdf-lib";
const pdfDoc = awaitPDFDocument.load(readFileSync("large-contract.pdf"));
const compressed = await pdfDoc.save({ useObjectStreams: true });
// Upload compressed version// Solution 2: Check file size before uploadconstMAX_SIZE_MB = 10; // Varies by planconst fileSizeMB = readFileSync("contract.pdf").length / (1024 * 1024);
if (fileSizeMB > MAX_SIZE_MB) {
thrownewError(`PDF is ${fileSizeMB.toFixed(1)}MB, max is ${MAX_SIZE_MB}MB`);
}
Scenario 6: Webhook Not Receiving Events
Checklist:
1. Webhook URL uses HTTPS (HTTP is rejected)
2. Webhook is enabled in Team Settings > Webhooks
3. Correct events are selected (document.completed, etc.)
4. Your endpoint returns 200 within 10 seconds
5. If using ngrok: tunnel is active and URL matches dashboard config
6. Check X-Documenso-Secret header matches your stored secret
Scenario 7: SDK Type Mismatches
// Error: argument type mismatch with SDK// The SDK uses specific enum strings, not arbitrary values// WRONGawait client.documentsRecipients.createV0(docId, {
email: "signer@example.com",
name: "Jane",
role: "signer", // Lowercase fails
});
// CORRECT: use uppercase enum valuesawait client.documentsRecipients.createV0(docId, {
email: "signer@example.com",
name: "Jane",
role: "SIGNER", // Must be uppercase: SIGNER, VIEWER, APPROVER, CC
});
// Field types are also uppercase: SIGNATURE, TEXT, DATE, NAME, EMAIL,// INITIALS, NUMBER, CHECKBOX, DROPDOWN, RADIO, FREE_SIGNATURE
Debugging Quick Commands
# Test API key
curl -s -w "\n%{http_code}" \
-H "Authorization: Bearer $DOCUMENSO_API_KEY" \
https://app.documenso.com/api/v1/documents?page=1&perPage=1
# Check self-hosted instance health
curl -s https://your-instance.com/api/health
# List documents to verify access
curl -s -H "Authorization: Bearer $DOCUMENSO_API_KEY" \
"https://app.documenso.com/api/v1/documents?page=1&perPage=5" | jq '.documents[].title'
