When attempting to post data to the Webflow CMS, you may encounter an error message. The error message can vary depending on the issue at hand. Here are a few common error messages and their potential causes:

"Validation failed"

This error message typically occurs when the data being submitted does not meet the validation requirements set for a specific field in the CMS. For example, if a text field requires a minimum character length and the submitted data doesn't meet that requirement, the validation will fail. Double-check the validation rules set for each field and ensure that the data being submitted adheres to these rules.

"Unique field or ID constraint"

This error message is shown when the submitted data conflicts with an existing entry in the CMS that requires a unique value. For example, if you have a "Slug" field with a unique constraint and a duplicated slug is submitted, this error will occur. Make sure that each unique field or ID is indeed unique for every entry.

"Rate limit exceeded"

Webflow enforces rate limits to prevent abuse and maintain performance for all users. If you repeatedly make too many API requests within a specific time frame, you may encounter this error. To resolve this, you can either wait until the rate limit resets or upgrade to a plan with a higher rate limit.

"API key authorization failed"

This error message indicates that the API key used for authentication is either incorrect or expired. Double-check the API key being used and ensure it is valid and matches the one provided in the Webflow dashboard.

When encountering an error message while attempting to post data to the Webflow CMS, it is important to carefully read the details provided in the error message. This information will give you a clue about the issue and help you troubleshoot and resolve it effectively.
