Atom Customers API
REST service for managing the customer (cliente) records behind Atom's WhatsApp conversations. The provider knowledge base documents three operations: create or update a customer, retrieve the list of all customers with required and optional parameters, and retrieve a single customer's details by ID. Requests are authenticated with an account bearer token issued from the Atom admin panel and sent in the Authorization header. It is the documented integration path for CRMs and in-house systems that have no native Atom connector. No OpenAPI is published for this API.
