Likely Causes
  1. Payload schema, field type, or request shape does not satisfy endpoint contract.
  2. One or more required fields are missing, malformed, or semantically inconsistent.
  3. Client serialization transformed values in a way the API rejects at validation time.
How to Fix It
1
Shopify: Validate request payload against the latest API schema before sending.
2
Inspect field-level errors and correct type, format, and required-field completeness.
3
Replay the same call with a minimal valid payload to isolate offending attributes.
4
Enforce strict client-side validation and schema version pinning in your integration.
5
Add contract tests so this validation pattern is caught before deployment.
Pro Tip
This is a common issue that most users can resolve without specialized tools. Try the first step before moving on to more complex solutions.
