422 Unprocessable Entity

You may encounter a 422 error if your query input results in more than 2000 potential matches. This typically indicates that the input is not specific enough to uniquely resolve a record set.

Why it happens:
The IDLink API enforces a threshold of 2000 records to protect system performance and ensure manageable result sets.

How to resolve:
Refine your input to make it more unique. For example:

Use full email addresses instead of domains.
Include full phone numbers with country code.
Narrow your search by specifying more fields where supported.
