Validation errors

If the API fails to validate a request, it will respond with a 400 validation error message (JSON or XML) describing the issue.

The below validation errors are the most common and will respond with some details, including a list of validation messages. Validation errors typically occur when a request is malformed -- usually because a field has not been given the correct value type, or the JSON is misformatted.

Error types

• EndpointParameterError: caused by incorrect input parameters
• BooleanRequirement: the value must be either "true" or "false"
• ContentRequirement: the content supplied is blacklisted
• DateRequirement: the value must be a proper date
• IdRequirement: the value must be an integer greater than 0
• ImmutabilityRequirement: the value cannot be changed once it has been set
• IntegerRequirement: the value should be an integer
• NoDuplicatesRequirement: there is a duplicate value supplied in the request
• NotNullRequirement: the value cannot be null or missing

• ObjectValidationError: a problem with one of the properties on the object

  Some examples include:

  • TextWithNoUrlRequirement: the value must not contain URLs
  • TextWithNoHtmlRequirement: the value must not contain HTML
  • DateRequirement: the value must contain a date
  • EmailAddressRequirement: the value must contain an email address
  • ValidTextLengthRequirement: the value does not contain a valid number of characters
• RelationshipRequirement: a relationship between two objects or related properties has not been met
• SyntaxRequirement: the HTML is not valid or could not be parsed
• UniquenessRequirement: the supplied name is not unique
• UrlRequirement: the supplied value should be a valid url

Example

For example, if you try to update a contact with id "sandwich" instead of an integer greater than zero:

GET https://.../data/contact/sandwich
Accept: application/json
		

You will receive a 400 response with "IdRequirement" error:

    {
        "type":"EndpointParameterError",
        "parameter":"id",
        "requirement":{
            "type":"IdRequirement",
            "isRelativeAllowed":false
        },
        "value":"sandwich"
    }
            

From the above "Error types" list, we see that this error means " the value must be an integer greater than 0".
