If you receive this error message, please review your $filter parameter and look at the features listed in the Filtering in REST page.

This error indicates that you had two clauses that did not contain a conjunction such as AND or OR indicating how they relate to each other.

An example that would trigger this error message is this:

GET /api/v2/companies?$filter=companyCode eq 'DEFAULT' name eq 'Bob''s Artisan Pottery'

To fix it, please add the word AND or OR between the first filter criteria and the second one:

GET /api/v2/companies?$filter=companyCode eq 'DEFAULT' AND name eq 'Bob''s Artisan Pottery'
