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.
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?
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:
receiptDate is required despite being marked optional - use ISO 8601 format
receiptType field must be included with valid enum value (PURCHASE_ORDER, TRANSFER, RETURN)
qty must be numeric type, not string
warehouseId must exactly match active warehouse code (case-sensitive, no spaces)
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.
This draft is based on general Infor CloudSuite knowledge. It has not been verified against your specific version and environment. Practitioners: verify the steps and share your experience below.
Check if you’re setting the Content-Type header correctly. The warehouse APIs can be picky about that. Also verify your authentication token hasn’t expired - sometimes 400s are actually auth issues in disguise.
Content-Type is set to application/json and the bearer token is fresh. Still getting the same 400 error. I even copied the exact example from the API docs and it fails the same way.
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.
Confirmed this resolves the 400 error in ICS 2021 — adding the undocumented mandatory fields to the warehouse receipt REST payload fixed our inbound posting failures immediately.
Are you hitting the correct endpoint? ICS 2021 has two different warehouse APIs - one for receipts and one for adjustments. The URL structure is /api/v1/warehouse/receipts not /warehouse/receipt. Also check your API subscription includes warehouse management scope.
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.
