Migrating from CNPJa
Migration from CNPJa is straightforward. The/cnpj/{cnpj} endpoint supports the formato=cnpja parameter, which returns the response in the same format as the CNPJa API.
Step 1: Change the base URL
Step 2: Add authentication
Add thetoken parameter to the URL or the Authorization: Bearer {token} header.
Step 3: Test
The response will have the same format as CNPJa. No changes to parsing are required.Differences
When to remove the formato parameter
We recommend that, after validating the migration, you remove the formato=cnpja parameter and adapt your code to this API’s native format. The native format offers more fields and better structured data.
