Warehouse inbound receipt posting via REST API returns 400 Bad Request after payload validation, blocking urgent stock updates

We’re trying to automate warehouse inbound receipts using the CloudSuite REST API but consistently getting 400 Bad Request errors. The payload structure matches the API documentation exactly - we’ve verified every field against the schema. Tested with both Postman and curl with identical results.

{
  "receiptId": "RCV-2025-0315",
  "warehouseId": "WH-CENTRAL",
  "items": [{"sku": "SKU-1234", "qty": 100}]
}

The response just says “Bad Request” with no additional error details or validation messages. This is blocking our stock update automation and causing delays in inventory availability. Has anyone encountered similar issues with warehouse receipt APIs in ICS 2021?

In ICS 2021, the warehouse receipt API requires a specific date format that’s not well documented. The receiptDate field needs to be included even though it’s marked optional in the schema. Also, the warehouseId must match exactly what’s configured in your tenant - check for trailing spaces or case sensitivity issues. We had similar problems until we discovered the API validates against active warehouse codes only, not just any configured warehouse.

The 400 error without details usually means payload validation failed before reaching the business logic. Try enabling verbose logging on your API client. In our case, we found that numeric fields were being sent as strings which the API silently rejected. The qty field should be an integer, not a string “100”. Also verify your sku values exist in the item master.

Since your payload matches documentation but still fails with both Postman and curl, and you’re getting no detailed error information in the response, this is a classic case of undocumented API requirements in ICS 2021. Here’s what you need to address:

Payload Structure Issues: The warehouse receipt API requires additional mandatory fields not clearly marked in the docs. Add these to your payload:

{
  "receiptId": "RCV-2025-0315",
  "receiptDate": "2025-03-15T10:23:00Z",
  "warehouseId": "WH-CENTRAL",
  "receiptType": "PURCHASE_ORDER",
  "items": [{"sku": "SKU-1234", "qty": 100}]
}

Validation Points:

  1. receiptDate is required despite being marked optional - use ISO 8601 format
  2. receiptType field must be included with valid enum value (PURCHASE_ORDER, TRANSFER, RETURN)
  3. qty must be numeric type, not string
  4. warehouseId must exactly match active warehouse code (case-sensitive, no spaces)
  5. sku values must exist in item master and be active

Getting Better Error Details: Since the API doesn’t return detailed validation errors, enable CloudSuite API logging in the admin console under Integration > API Logs. This will show server-side validation failures. Also add the header X-Infor-Debug: true to your requests for more verbose responses in non-production environments.

Common Causes for 400 with No Details:

  • Missing required fields that aren’t documented as required
  • Data type mismatches (string vs number)
  • Invalid enum values
  • References to inactive or non-existent master data
  • Tenant-specific custom validations

Test with the updated payload structure and check the server logs. If it still fails, verify your API subscription includes the warehouse management scope and that your user role has receipt posting permissions. The UI working doesn’t guarantee API access - they use different permission models in ICS 2021.
