Quote configure price API returns 500 Internal Server Error during updates

We’re experiencing 500 Internal Server Error responses when trying to update quotes via the configure price API. Quote creation works fine, but updates consistently fail.

Update request:


PATCH /crm/v3/objects/quotes/{quote-id}
{
  "properties": {
    "hs_expiration_date": "2025-01-31"
  }
}

Error: `{“status”:“error”,“message”:“Internal server error”,“correlationId”:“xyz-789”} This is blocking our quote management workflow in hs-2021. The error logging doesn’t provide much detail. How can we properly debug what required fields are missing or what’s causing the server error? Has anyone successfully implemented quote updates via API?

The quote ID is definitely valid - I can retrieve the quote successfully with GET requests using the same ID. I’ll try the full timestamp format for the expiration date.

500 errors usually indicate a server-side issue rather than a request problem. Check if the quote ID is valid and the quote exists. Also try using the full date-time format instead of just date.

I’ve resolved this exact 500 error multiple times with the quote API in hs-2021. The issue is complex because quote updates have hidden validation rules and required fields that aren’t well documented. Here’s the complete solution:

1. API Request Body Structure: Quote updates in hs-2021 require maintaining the complete quote structure. You can’t just update one property - you need to include key related data:


PATCH /crm/v3/objects/quotes/{quote-id}
{
  "properties": {
    "hs_expiration_date": "2025-01-31T23:59:59.000Z",
    "hs_title": "existing-quote-title",
    "hs_status": "DRAFT"
  }
}

Key requirements:

  • Use full ISO 8601 timestamp format for dates (not just YYYY-MM-DD)
  • Include hs_title even if not changing it
  • Include hs_status to confirm quote state
  • Ensure status allows modifications (DRAFT or PENDING)

2. Required Fields for Updates: Even for PATCH requests, the quote API validates these fields:

  • hs_title: Quote title/name (required)
  • hs_expiration_date: Must be future date
  • hs_status: Must be valid status (DRAFT, PENDING, APPROVED, REJECTED)
  • hs_currency: Currency code (if quote has line items)

To get current values before updating:


GET /crm/v3/objects/quotes/{quote-id}?properties=hs_title,hs_status,hs_currency

Include these in your PATCH request to avoid validation failures.

3. Error Logging and Debugging: 500 errors in hs-2021 quote API often mask specific validation issues. To debug properly:

a) Check Quote State:

  • Quotes in APPROVED or REJECTED status can’t be updated via API
  • Quotes sent to customers (hs_sent_to_customer = true) have restricted updates
  • Verify status before attempting update

b) Validate Associations:

  • If quote has line items, they must remain valid
  • Associated deal must still exist and be accessible
  • Contact associations can’t be broken

c) Test with Minimal Update:

Start with just status field to isolate the issue:


PATCH /crm/v3/objects/quotes/{quote-id}
{
  "properties": {
    "hs_status": "DRAFT"
  }
}

If this works, add fields incrementally.

4. Common Causes of 500 Errors:

Line Item Conflicts: If the quote has line items, updating certain properties requires line item recalculation. The API fails if:

  • Line items reference deleted products
  • Pricing calculations result in invalid values (negative amounts)
  • Currency changes don’t match line item currencies

Solution: Retrieve line items first and ensure they’re valid:


GET /crm/v3/objects/quotes/{quote-id}/associations/line_items

Deal Association Issues: Quotes associated with closed deals can’t be updated. Check deal stage:


GET /crm/v3/objects/quotes/{quote-id}/associations/deals

Ensure associated deal is in an open stage.

Custom Property Validation: Custom required properties on quote object must be included in updates. Check:

  • Settings > Properties > Quote Properties
  • Filter by Required = Yes
  • Include all required custom properties in request body

5. Implementation Strategy:


// Pseudocode for safe quote updates:
1. GET quote by ID to retrieve current state
2. Validate quote status is DRAFT or PENDING
3. Check if quote is sent to customer (restrict updates if true)
4. Retrieve associated line items and validate they exist
5. Build update request with current values + changes
6. Include all required properties (title, status, expiration)
7. Send PATCH request with full property set
8. If 500 error, use correlationId with HubSpot support

6. Error Recovery: When 500 errors occur:

  • Log the correlationId immediately
  • Capture the complete request body that failed
  • Check quote history in HubSpot UI to see if partial update occurred
  • Contact HubSpot support with correlationId for server-side logs
  • They can provide specific validation failure details not exposed in API

7. Best Practices:

  • Always GET current quote state before updating
  • Include all required fields in PATCH requests (don’t rely on defaults)
  • Use full ISO timestamps for all date fields
  • Validate quote status and associations before attempting updates
  • Implement retry logic with exponential backoff for 500 errors
  • Log all requests and responses for debugging

After implementing these changes, especially including the full property set with current values and proper timestamp formatting, your quote updates should succeed. The key insight is that hs-2021’s quote API treats PATCH more like PUT in terms of validation - you need to provide a complete valid state, not just the changed fields.
